Dynamic 3-D contrast-enhanced angiography of cerebral tumours and vascular malformations.

We describe the applicability and clinical use of dynamic 3-D contrast-enhanced MR subtraction angiography performed at 3 T with parallel imaging and intelligent k-space readout for imaging both treated and untreated cerebral arteriovenous malformations (AVMs), AV fistulae (AVFs) and brain tumours. An in-plane submillimetre spatial resolution with temporal resolution of one image per 1.3 s was obtained.
