sodium-pertechnetate-tc-99m and Brain-Concussion

Encephaloangioscintigraphy performed in 30 patients with a closed craniocerebral trauma has shown simultaneous inhibition of the venous cerebral blood flow both in the vascular regions of the cerebral hemispheres and in the lateral sinuses indicating the common pathogenesis of disorders of the venous circulation in these parts of the circulatory bed. The most informative characteristic feature of the venous outflow is a period of RP half-life, determined on a radiocirculogram of the brain. The diagnostic efficacy of the above method in the detection of disorders of the venous circulation of the brain in some vascular regions provides an opportunity for a purpose-oriented use of adequate methods of reflexotherapy.

Using radioindicative methods, cerebral hemodynamics was studied in 62 children aged 3 to 15 years in the acute period of head injury. The diagnostic findings of focal intracranial lesions are presented. On the basis of the clinical-neurologic findings, the patients were divided into three groups depending on the degree of the severity of traumatic lesion to the brain. Patients with mild and moderately grave craniocerebral injury were shown to have a symmetric decrease in the blood flow intensity while severe traumas were associated with disorders of vascular passage of the preparation in one cerebral hemisphere in the presence of general reduction in the cerebral blood flow.
