Both CTA and contrast-enhanced MRA provide highly accurate assessment of severe carotid artery stenosis, and are an improvement over traditional time-of-flight MRA in the depiction of great-vessel origins and the cervical vertebral arteries. Both show promise in acute stroke.Wednesday, 11 Jun 2003 15:22:07 GMT
