Dynamic radioisotope study of the internal carotid region of the neck in cerebrovascular disease.

The results of radionuclide angioscintigraphy were evaluated in patients with stricture or occlusion of the extracranial part of the internal carotid artery. Time-activity curves for the first 13 s were generated from left and right internal carotid regions of interest of the neck. The differences between the counts from symmetric regions of interest were measured. We observed decreased activity in regions of interest in cases with stricture of the internal carotid. The first 13 s were significant for evaluation of the extracranial part of the internal carotid.

Estimation of the dynamic carotid flow in patients with normal radionuclide cerebral perfusion.

Radioisotope angioscintigraphy following intravenous injection bolus of 99mTc-pertechnetate was performed in 49 patients with cerebrovascular disturbances. The region of interest placement on the sequential analog images of both middle cerebral and internal carotid arteries and time-activity curves were displayed on the video monitor. In 35 cases of this group we have noticed symmetrical cerebral perfusion and a significant difference between right and left internal carotid flow, and in 33 cases of which dynamic studies were made stenosis or occlusion of the extracranial part of the carotid internal artery was revealed by the X-ray angiography.

[Angiographic diagnosis of vascular spinal abnormalities].

The authors describe 6 cases of intraspinal haemangiomas, their manifestations clinical and radiological treatment. In 2 cases vascular anomalies were located in the cervical segment, in 3 cases in the thoracic segment and in 1 case in both of these segments. The diagnosis was established by means of selective catheterization of posterior intervertebral arteries and lumbar arteries (4 cases), aortic arch angiography (1 case) and subclavian artery arteriography (1 case) by the Seldinger method. The authors describe in detail the method of selective sinal arteriographies and their role in establishing the extent and location of the lesions and the supplying arteries.
