Evaluation of prototype equipment for digital subtraction angiography in diagnosing intracranial lesions

M Takahashi, Y Hirota, H Bussaka, T Tsuchigame, M Miyawaki, S Ueno, Y Matsukado and Y Hirata

Two prototype units for digital subtraction angiography have been developed by Japanese manufacturers. Their performance in demonstrating various intracranial lesions in 121 patients was evaluated. Comparison with conventional selective catheter angiography was possible in 77 patients. Digital subtraction angiography proved useful in preoperative evaluation of pituitary tumors when transsphenoidal surgery was being considered; demonstration of faint tumor stains which might be missed on conventional angiography; demonstration of larger aneurysms, arteriovenous malformations, and tumors as a screening technique; demonstration of abnormalities involving the dural sinuses; and follow- up of patients after surgery or embolization.
