The purpose, significance and indication of cere-bral angiotomography are discussed and the find-ings of these 63 cases presented.

Princeps 50 (CGR, France) apparatus for cranial tomography was used with angle of swing of 30 degrees upon tomography.

The purpose of present method was summarized as follows : 1) Differential visualization of branches of the anterior and middel cerebral artery, 2) Se-lective visualization of deep cerebral vein such as internal cerebral vein, 3) Detailed demonstrations of the efferent veins in arteriovenous malformation, especially in the evaluation of the situation withdoubtful connection with the deep cerebral veins, 4) Detection of small angioma or abnormal vascular anastomosis.

In the medain tomography of the lateral view of the arterial phase, only the the anterior cerebral artery is visualized. No satisfactory results were obtained in the tomography of the lenticulostriate artery. In cases of intracranial aneurysm, only the blood vessels in the neighborhood of the aneurysm including parent vessel are visualized, giving a good referece for operation. In cases of brain tumor, degree of the vascularity in the tumor is clarified by the angiotomography.

Visualization of deep cerebral veins such as inter-nal cerebral vein represents one of the best indi-cations for this method. Especially in the lateral view, it is possible to demonstrate deep cerebralvein alone, without interference by superficial cere-bral veins. Furthermore detailed demonstration of the subependymal veins is probably uselful in the diagnosis of ventricular or paraventricular tumor. The advance of this method consists of the pos-sibility of interpretation of vascularity without interference by the density of the skull and re-solution of the difficulty of interpretation of over-lapping blood vessels. Since tomography is possible from any angle, there is no need for changing the position of patients head and body upon radio-graphy. Paucity of significance of antero-posterior tomography as compared with lateral tomography and increase of the amount of opaque media might represent drawbacks of this method.
