Forty-five patients with spontaneous intracerebral hemorrhage (ICH) we
re studied prospectively by dynamic CT and cerebral angiography. The a
ccuracy of dynamic CT in demonstrating:the underlying vascular cause i
n ICH was evaluated. Dynamic CT correctly predicted 90% of aneurysms,
83% of AVMs and 100% of normal studies as compared to angiography. Cer
ebral angiography can be obviated in patients where dynamic CT does no
t show any obvious vascular anomaly.
