Iodine 131 metaiodobenzylguanidine scintigraphy of medullary carcinoma of the thyroid.
    Southern medical journal, 1991, Volume: 84, Issue:5

    We have presented a case of sporadic medullary carcinoma of the thyroid with documentation of localization of tracer 131I-MIBG within the primary neoplasm. A review of the nuclear medicine literature of localization techniques for MCT demonstrates that 131I-MIBG, while an excellent choice for diagnosis of pheochromocytoma and neuroblastoma, produces low yield and unpredictable concentration in other neural crest apudomas, including MCT. A low incidence of true-positive results with 131I-MIBG uptake and a high incidence of false-negative results make this radiopharmaceutical a suboptimal choice for diagnostic studies, but a potentially promising one as a therapeutic agent.

Sensitivity and specificity of nuclear medicines (DTPA and DMSA) with magnetic resonance imaging in diagnosing bone metastasis.
    Nuclear medicine review. Central & Eastern Europe, 2022, Volume: 25, Issue:2

    The frequency of bone metastases in individuals increases at advanced stages of cancer, mostly in patients suffering from lung, breast, or prostate cancer. The study aims to evaluate the effectiveness of bone metastases diagnosis of nuclear medicine, CT scan, and MRI in detecting bone metastases among patients with lung, breast, and prostate carcinoma.. Retrospective study design was adopted for the analysis of 120 recruited patients (with the presence of bone metastasis) following a series of examinations and tests.. Better sensitivity (73.33%) and specificity (94.66%) for MRI as compared to SPECT. MRI also proved to be more sensitive (68%) and specific (95.74%), as compared to the findings of the CT scan.. The results conclude that MRI provided favorable diagnostic performance for bone metastasis. It emphasizes that diagnosis using MRI may enable practitioners to devise optimal carcinoma treatment strategies. The healthcare practitioners need to assess the MRI findings to determine improved treatment plans.

Technetium 99m pentavalent dimercaptosuccinic acid and thallium 201 in detecting recurrent medullary carcinoma of the thyroid.
    Canadian journal of surgery. Journal canadien de chirurgie, 1992, Volume: 35, Issue:4

    To compare the effectiveness of thallium chloride 201 and technetium 99m pentavalent dimercaptosuccinic acid in evaluating medullary carcinoma of the thyroid (MCT), eight patients with a history of MCT underwent imaging with both radiopharmaceuticals. Thallium 201 consistently gave superior images, as well as providing one less false-negative scan. Positive scans were obtained in patients with elevation of basal calcitonin levels to more than 1,000 ng/L. All of the patients with positive scans had clinical evidence of local recurrence. Improved imaging with thallium 201 was obtained by early scanning.

Pentavalent Tc-99m DMSA scintigraphy. Prospective evaluation of its role in the management of patients with medullary carcinoma of the thyroid.
    Clinical nuclear medicine, 1991, Volume: 16, Issue:4

    Ten patients with suspected primary, recurrent or metastatic medullary carcinoma of the thyroid (MCT) were studied prospectively with Tc-99m(V) DMSA. Of these, two patients had primary disease, seven patients were asymptomatic but had persistent and serial elevations in serum calcitonin following previous thyroid resections for MCT, and one asymptomatic patient with normal serum calcitonin was studied because of suspected hilar nodes metastases. The serial calcitonin peak in the patients was 0.04-43ng/ml (normal less than 0.08ng/ml). Scintigraphy was considered positive in seven of the asymptomatic patients and equivocal in one. The two patients with primary disease had increased uptake before but not after thyroidectomy. Primary disease, localized recurrence and distant metastases in soft tissue (nine patients) and bone (one patient) were detected in these patients, and this resulted in early surgical resection (five patients) and radiotherapy (one patient). We conclude that Tc-99m(V) DMSA is a useful imaging agent in the evaluation of asymptomatic MCT patients with hypercalcitonemia.

Search for polynuclear pentavalent technetium complex of dimercaptosuccinic acid [Tc(V)-DMS] tumour localization mechanism. I. Medullary thyroid carcinoma animal model.
    European journal of nuclear medicine, 1991, Volume: 18, Issue:10

    To search for the tumour localization mechanism of Tc(V)-DMS, a polynuclear pentavalent technetium complex of dimercaptosuccinic acid [Tc(V)-DMS], the development of medullary thyroid carcinoma (MTC) bearing mouse model was considered. Subcutaneously transplanted tumour was allowed to grow for 2, 4 and 6 weeks, and the influence of the tumour stage on the biodistribution of Tc(V)-DMS was screened. High radioactivity uptake in the tumour tissue was observed, and this accumulation showed a direct correlation with tumour growth and calcitonin secretion, the MTC marker detectable in the blood serum. The gathered data implicated some calcitonin-related factors as the mediator in the Tc(V)-DMS localization; participation of a phosphate-like oxoanion, TcO4(3-), is strongly suggested not only by the high radioactivity accumulation in the calcitonin-producing tumour but also by the accumulation in the bones of this model animal.

Pentavalent technetium-99m (V)-DMSA uptake in a pheochromocytoma in a patient with Sipple's syndrome.
    Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1990, Volume: 31, Issue:1

    This case report describes 99mTc(V)-dimercaptosuccinic acid (DMSA) accumulation in a pheochromocytoma in a patient with Sipple's syndrome. Scintigraphy with 99mTc(V)-DMSA demonstrated uptake in medullary carcinoma of the thyroid gland (MCT). Iodine-131 metaiodobenzylguanidine (MIBG) scintigraphy showed the bilateral pheochromocytomas but did not demonstrate uptake in the MCT.

[Medullary carcinoma of the thyroid and 99mTc(V)-DMSA scintigraphy. Clinical results with a new radiopharmaceutical].
    RoFo : Fortschritte auf dem Gebiete der Rontgenstrahlen und der Nuklearmedizin, 1990, Volume: 153, Issue:5

    99mTc(V)-DMSA scintigraphy is a non-invasive diagnostic tool for diagnostic differentiation and localisation of medullary carcinoma of the thyroid. For primary tumours its sensitivity is 77%. This diagnostic means is not only helpful for the diagnosis of primary tumours, but is especially informative for recidives and metastases of the medullary carcinoma of the thyroid. Its sensitivity for recidives and metastases is 66%. The sensitivity obtained in our study, which included four patients, corresponded to that reported in the literature.

New tracers for the imaging of the medullary thyroid carcinoma.
    Nuclear medicine communications, 1989, Volume: 10, Issue:4

    I-MIBG and 99Tcm(V)-DMSA have been recently proposed as scintigraphic markers of the medullary thyroid carcinoma (MTC). Thirty two patients were examined with 131I- or 123I-MIBG and 26 of these were re-examined with 99Tcm(V)-DMSA (planar and SPECT). From our experience we can draw the following conclusions: (1) the scintigraphic attempt was useless in patients with normal levels of plasma calcitonin (CT): (2) in patients with high plasma CT levels, the sensitivity of the MIBG was better in familiar (3/3 true positive) than in sporadic disease (7/21 true positive; overall sensitivity = 42%); the 99Tcm(V)-DMSA was positive in 16/19 cases, (overall sensitivity = 84%) even in cases which had been false negative with MIBG (6 patients); (3) no false positive results were found; (4) the scan with 99Tcm(V)-DMSA is then suggested as the first imaging approach during the follow up in patients affected by MTC and still having high levels of plasma CT. The MIBG scan should be limited to the patients in whom the possible use of MIBG therapy has to be investigated.

Tc-99m-(V)-DMSA: the new sensitive and specific radiopharmaceutical for imaging metastases of medullary thyroid carcinomas?
    Hormone and metabolic research. Supplement series, 1989, Volume: 21

    In the follow-up of five patients with histologic proven medullary thyroid carcinoma (MTC) and raised serum calcitonin and CEA levels the pentavalent Tc-99m-(V)-DMSA and the Tc-99m-MDP bone scan had the highest sensitivity in the localisation of metastases. Both methods are not tumor specific. A false positive Tc-99m-(V)-DMSA uptake in an old osteomyelitis of one vertebra could be demonstrated. The J-123-MIBG and In-111-F(ab2)' antibody scan did not allow to localise one of the above described metastases. In conclusion in the follow-up of patients with MTC and elevated tumor marker concentrations the Tc-99m-(V)-DMSA and the Tc-99m-MDP bone scan should be the second diagnostic procedures after sonography has been performed.

Medullary carcinoma of the thyroid: management of persistent hypercalcitonaemia utilizing [99mTc] (v) dimercaptosuccinic acid scintigraphy.
    The British journal of surgery, 1989, Volume: 76, Issue:12

    Whole body scintigraphy with [99mTc] (v)dimercaptosuccinic acid (pentavalent DMSA) was performed in seven patients with histologically confirmed medullary carcinoma of the thyroid (MCT). Six of these patients had undergone previous thyroid resections for MCT and, although asymptomatic at the time of pentavalent DMSA scintigraphy, had persistent and serial elevations in their plasma calcitonin levels. One additional patient was scanned before and after total thyroidectomy for MCT. The pentavalent DMSA scintigram demonstrated either local neck recurrence (three patients) or distant metastases (two patients) in five of the six asymptomatic patients. In one asymptomatic patient only equivocal neck uptake was demonstrated. Since he had only minimal calcitonin elevations, repeat neck exploration was not performed. The one patient studied before thyroid resection for MCT demonstrated neck uptake before, but not after, total thyroidectomy. The results of the scintigrams had significant impact on patient care and resulted in neck re-exploration (three patients), neck biopsy (one patient), and lumbar spine biopsy and subsequent radiotherapy (one patient). These data demonstrate pentavalent DMSA to be a sensitive localizing agent in the evaluation of asymptomatic MCT patients with hypercalcitonaemia. Accurate targeting of treatment may be shown in due course to have a beneficial impact on survival.

Experience in imaging medullary thyroid carcinoma using 99mTc (V) dimercaptosuccinic acid (DMSA).
    Henry Ford Hospital medical journal, 1989, Volume: 37, Issue:3-4

    99mTc (V) dimercaptosuccinic acid (DMSA) is a new tumor imaging agent that has been successfully used to image patients with medullary thyroid carcinoma (MTC). Since 1986, studies have been performed in 32 patients with histologically proven MTC at Guy's Hospital, London, England. Five patients with primary tumor were studied prior to surgery, four patients were studied after successful removal of the primary tumor, and 26 patients with biochemical evidence of recurrence were studied. Eight patients were studied serially to assess progression of disease, and four patients were studied before and after surgery. Twenty-one of the 26 patients with disease had positive scans with four false-negative scans and three true negative scans. One patient had a false-positive scan (sensitivity 80%, specificity 75%). Two of the false-negative scans were obtained in patients with moderate but stable elevations of calcitonin but no other evidence of recurrence. One false-negative scan was obtained in a patient who was discovered on screening to have an abnormal pentagastrin response, and a small 1 cm tumor was subsequently removed. Uptake in local neck recurrence was frequently intense, but uptake at sites of bone metastases was less marked. 99mTc (V) DMSA is an inexpensive radiopharmaceutical which produces good quality images and has been shown to have an acceptable sensitivity and specificity in the follow-up of patients with MTC and thereby contributes significantly to the management of these patients.

Diagnostic and therapeutic potential of new radiopharmaceutical agents in medullary thyroid carcinoma.
    Henry Ford Hospital medical journal, 1989, Volume: 37, Issue:3-4

    Recently developed radiopharmaceuticals have been proposed for imaging medullary thyroid carcinoma (MTC) with some having therapeutic potential. This study compares the imaging results obtained with radioiodinated meta-iodo-benzylguanidine (MIBG), 99mTc (V) DMSA, and 131I F(ab')2 anti-carcinoembryonic antigen (anti-CEA) in a group of MTC patients. In 23 patients 131I MIBG imaging showed a high specificity (no false-positive results) but a less satisfactory sensitivity (50%). In 12 patients 99mTc (V) DMSA revealed a better sensitivity (77%) but a lower specificity (three false-positive results). Positive results were obtained in two of three patients studied with 131I F(ab')2 anti-CEA. These data suggest that the highly sensitive 99mTc (V) DMSA should be considered as a first choice procedure followed by the highly specific radioiodinated MIBG to confirm the initial results. Since radioiodinated MIBG imaging may have therapeutic usefulness, 131I MIBG was evaluated in an integrated treatment protocol in four cases of proven MTC. The preliminary results obtained were encouraging.

The role of radiopharmaceuticals MIBG and (V) DMSA in the diagnosis of medullary thyroid carcinoma.
    Henry Ford Hospital medical journal, 1989, Volume: 37, Issue:3-4

    The diagnostic value of 123/131I meta-iodo-benzylguanidine (MIBG) and 99mTc (V) dimercaptosuccinic acid (DMSA) was investigated in 12 patients with proven medullary thyroid carcinoma (MTC). Scintigraphic imaging with DMSA was negative in nine of 12 patients. Scintigraphy with MIBG was positive in only one case. In proven primary or recurrent disease, DMSA sensitivity was 50% and MIBG sensitivity was 25%. Such sensitivities become much lower in subjects with high calcitonin (CT) levels who have had negative surgical explorations: DMSA 17% and MIBG 0%. DMSA detected tumor in 25% of the patients and MIBG in only 8%. The positivity of these scintigraphies appears to be unrelated to carcinoembryonic antigen and CT plasma levels. Such data suggest that scintigraphies with MIBG and DMSA are only modestly useful in the diagnosis of MTC.

Pentavalent [99mTc]DMSA, [131I]MIBG, and [99mTc]MDP--an evaluation of three imaging techniques in patients with medullary carcinoma of the thyroid.
    Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1988, Volume: 29, Issue:1

    Nine patients with histologically proven medullary carcinoma of the thyroid (MCT) were imaged using pentavalent [99mTc]dimercaptosuccinic acid [(V)DMSA], [131I] metaiodobenzylguanidine (MIBG) and [99mTc]methylene diphosphonate (MDP). Technetium-99m (V)DMSA demonstrated most of the tumor sites in eight patients with proven metastases, with an overall sensitivity of 95% in lesion detection. Iodine-131 MIBG showed definite uptake in some of the tumor sites in three of the nine patients imaged, with equivocal uptake seen in a further one patient, with sensitivity of only 11% for lesion detection. Technetium-99m MDP demonstrated bony metastases only, in four of the patients imaged yielding a sensitivity of 61%. Technetium-99m (V)DMSA has been demonstrated in this study to be a useful imaging agent in patients with MCT, showing uptake in significantly more lesions and with better imaging qualities than [131I]MIBG, and with the ability to detect soft tissue as well as bony metastases.

Clinical evaluation of 99mTc(V)-dimercapto succinic acid (DMSA) for imaging medullary carcinoma of thyroid and its metastasis.
    European journal of nuclear medicine, 1988, Volume: 13, Issue:10

    99mTc(V)-DMSA kits developed by the Radiopharmaceutical Division, Bhabha Atomic Research Centre, have been evaluated for potential use in scanning medullary carcinoma of the thyroid and its metastases. There were 15 patients with proved medullary carcinoma and 6 patients with other differentiated thyroid carcinoma. Amongst the 15 patients with medullary carcinoma, 12 (80%) showed positive localisation either in the primary or one or more metastatic sites. None of the six patients with carcinoma other than medullary showed increased concentration of 99mTc(V)-DMSA. Of the 37 known metastatic sites in 15 patients with medullary carcinoma, 24 showed concentration of 99mTc(V)-DMSA (64.9%). In addition, 99mTc(V)-DMSA concentration was seen in 14 sites where no evidence of metastasis was revealed. The incidence of 99mTc(V)-DMSA concentration in soft tissue and bone metastasis was similar.

New radionuclide tracers for the diagnosis and therapy of medullary thyroid carcinoma.
    Clinical nuclear medicine, 1988, Volume: 13, Issue:3

    Medullary thyroid carcinoma (MTC), a calcitonin-producing tumor that occurs in familial and sporadic forms, can be monitored satisfactorily with measurements of calcitonin and CEA in serum. However, locating the tumor site may be difficult. In the current review of the experience with four new radionuclide tracers for MTC, the relative value of each of these procedures is outlined. Total body imaging using TI-201 chloride and Tc-99m(V) DMSA are both sensitive techniques that can be used for the detection and follow-up of MTC. Imaging using I-131 MIBG and I-131 anti-CEA antibodies/fragments should be performed once the diagnosis and the tumor site have been established, to evaluate if patients might be amenable for therapy with one of these radiopharmaceuticals.

Sipple's syndrome with liver tumors examined by iodine-131 MIBG and technetium-99m(V)-DMSA.
    Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1988, Volume: 29, Issue:6

    This case report describes the localization and categorization of tumors using 99mTc(V)-dimercaptosuccinic acid and [131I]metaiodobenzylguanidine scans in a very uncommon case of medullary thyroid carcinoma associated with pheochromocytoma (Sipple's syndrome) and hepatocellular carcinoma. Technetium-99m(V)-dimercaptosuccinic acid showed accumulation only in medullary thyroid carcinoma, but [131I]metaiodobenzylguanidine scans were positive in both medullary thyroid carcinoma and pheochromocytoma. In advanced Sipple's syndrome, combined use of [99mTc(V)]dimercaptosuccinic acid and [131I]metaiodobenzylguanidine may be useful for the categorization of tumor mass lesions and planning appropriate therapy.

    In order to assess the role of 99Tcm pentavalent dimercaptosuccinic acid (99Tcm (V)DMSA) scanning in the management of patients with medullary carcinoma of the thyroid, we imaged 10 patients with histologically proven disease. Nine of the 10 patients were scanned after removal of the primary tumour, but with symptomatic or biochemical evidence of recurrence. One patient was imaged prior to thyroidectomy. In eight of the 10 patients 99Tcm(V)DMSA successfully identified tumour deposits, and it has been shown in this study to be a cheap, convenient radiopharmaceutical for studying this group of patients, producing high-quality images with low radiation doses, and contributing significantly to patient management.

Preparation and evaluation of 99mTc(V)-DMSA complex: studies in medullary carcinoma of thyroid.
    European journal of nuclear medicine, 1987, Volume: 12, Issue:12

    Consequent to the promising results reported with 99mTc(V)-DMSA for imaging certain types of soft tissue tumors, we have developed methods to prepare this radiopharmaceutical in three ways: from freshly prepared reagents, through the use of a two component kit and use of the standard renal DMSA kit by a modified recipe. The 99mTc(V)-DMSA complex has been subjected to paper electrophoretic and chromatographic procedures and also biodistribution studies. The distinctly different behaviour of this new product compared to that of the well known renal DMSA complex has been clearly established. Scintiimaging in a preliminary clinical trial in patients with medullary carcinoma of the thyroid has been encouraging.

A new imaging agent for medullary carcinoma of the thyroid.
    Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1984, Volume: 25, Issue:3

    Thyroid scintigraphy, using 99mTc(V) dimercaptosuccinic acid, was performed in four patients with pathologically confirmed medullary thyroid carcinoma and elevated serum calcitonin values. Significant uptake of the tracer was found in the clinically palpable cervical tumor masses, metastatic sites, and residual tumor. This finding, probably specific for medullary thyroid carcinoma, could be of great use in the diagnosis and the surgical follow-up.
