[Intra-arterial digital subtraction angiography (IADSA) of intracranial lesions (an analysis of 600 cases)].

ABSTRACT

Intracranial vessels were evaluated in 600 patients with IADSA. Among them, 100 cases were studied with both conventional angiography and IADSA. The advantages of IADSA are (1) Good image quality; (2) Examination time shortened; (3) Very useful for interventional neuroradiology, hence it can replace conventional cerebral angiography for preoperative evaluation in most cases.
