[Indium-111-oxine labeled platelet and leucocyte scintigraphy for diagnosis of thrombi and inflammation].
    Kaku igaku. The Japanese journal of nuclear medicine, 2001, Volume: 38, Issue:4

    There were many studies for diagnosis of localization and activity of thrombi and inflammation using indium-111-oxine labeled platelet (In-plt) and leucocyte scintigraphy (In-WBC), respectively. The study using these techniques is decreasing recently, because other diagnostic modarities have been developed and the techniques of these scintigraphy are complicated. However, because these scintigraphy are noninvasive, it is expected that these are widely applied to the clinical diagnosis and follow up. 1. Platelet scintigraphy can visualized thrombi and distinguish the activation of platelet aggregation. There were many reports and reviews. I reviewed recent studies in cardiovascular diseases and our cases. 2. Leucocyte scintigraphy (In-WBC) is usually used for the detection of inflammation. Furthermore, it is possible that In-WBC can detect inflammation of the arteriosclerotic lesion of the aortic wall. I introduced our studies of In-WBC in aortic aneurysma and aortic dissection. The In-WBC maybe useful for detection of inflammation of the aortic aneurysma and evaluation of prognosis of aortic dissection.

Leukocyte scintigraphy in the diagnosis of mycotic aneurysm.
    Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1992, Volume: 33, Issue:8

    Early diagnosis of a mycotic aneurysm is critical, but often unsuspected, due to the insidious onset of symptoms related to occult infection. This study was undertaken to assess the role of leukocyte scintigraphy in establishing the diagnosis of mycotic aneurysm. The records of all patients with possible mycotic aneurysm between 1985 and 1991 were reviewed. Seven patients had leukocyte scintigraphy and computed tomography (CT), three also had magnetic resonance imaging (MRI) and three had angiography as part of the diagnostic workup. CT and MRI detected aneurysms in five of the seven patients, but CT scans were misinterpreted in two patients as indicative of abscess only. In six patients, infection could not be differentiated from thrombosis, seroma or hemorrhage by CT or MRI. Leukocyte scintigraphy was positive in all four patients with infected aneurysms; it was negative in two of the three noninfected aneurysms and equivocal in the third. Leukocyte scintigraphy provided a useful early survey that demonstrated evidence of infected aneurysms in four patients and identified other sites of infection in two patients. Leukocyte uptake complemented CT, MRI and angiographic findings distinguishing between seroma/hematoma and adjacent infection to establish a preoperative diagnosis of infected aneurysms.

Is gamma-camera imaging of platelet deposition useful to assess the effectiveness of prostacyclin treatment?
    Biomedica biochimica acta, 1984, Volume: 43, Issue:8-9

    Platelet labeling with 111-In-oxinesulfate allows visualization of platelet deposition in the vascular bed. Scintigraphic studies were performed in 6 patients with "active" (PUR greater than 1.20) and 8 patients with "inactive" (PUR less than 1.20) atherosclerotic lesions of the femoral artery. Platelet deposition was also studied in 11 patients with implanted prosthetic vascular grafts and in 21 patients with an abnormal aneurysm of the aorta. Infusing 5 ng/kg/min PGI2 during 6 hours for 5 days into patients with "active"-atherosclerosis and aneurysms of the aorta resulted in a significant decrease of platelet deposition even after having stopped the infusion. There was no influence of PGI2 on PUR in patients with "inactive" lesions. The group of patients with implanted prosthetic grafts demonstrated also a significant decrease of PUR values during the PGI2-infusion, but reached baseline values soon after stopping the infusion. When platelet deposition is increased gamma-camera imaging provides valuable date on the influence of any kind of therapy on the in-vivo platelet function.

[Indium-111-oxine labeled platelet scintigraphy for detection of intracardiac and intravascular thrombi].
    Journal of cardiography, 1983, Volume: 13, Issue:3

    This study was designed to evaluate the efficacy of scintigraphy by using 111In-oxine labeled platelets for the detection of either intracardiac or intravascular thrombi. Fourteen cases of thrombi diagnosed or suspected on the basis of either angiography or two-dimensional echography were examined. They included four cases of left ventricular thrombi, three of left atrial thrombi, four of vascular thrombi and three of inflammatory disease. Platelet samples from the patients were labeled by 111In-oxine according to the method originated by Yui et al. The labeling efficiency was 72.4 +/- 9.8%. The platelets retained good function except for collagen aggregability. Hot areas of high quality in the scintigram were demonstrated in six cases including two with left ventricular thrombi, two with left atrial thrombi and two with vascular thrombi. These areas accorded well with the findings of angiography, echography or surgery. The removed thrombi had a layer of aggregated platelets on the surface. Platelet survival was shortened in a case of prosthetic valve endocarditis without a hot area, and was normal in four out of five cases including two with a hot area. It is concluded that this method is potentially predictive in detecting thrombi.

Diagnosis of arterial prosthetic graft infection by indium-111 oxine white blood cell scans.
    Circulation, 1982, Volume: 66, Issue:2 Pt 2

    Early and accurate diagnosis of infected prosthetic arterial grafts is difficult, despite the application of diverse diagnostic modalities. Delay in making the diagnosis is largely responsible for the high amputation and mortality rates associated with this complication. In nine patients with suspected graft infections, indium-111 white blood cell scanning was useful and accurate. Graft infection was proved in five cases and ruled out in three. One false-positive scan was due to a sigmoid diverticular abscess overlying the graft. Indium-111 white blood cell scans may improve the accuracy of diagnosing infected prosthetic grafts, which may result in better limb and patient salvage rates.
