  • Abstract
  • Look Inside

The usefulness for evaluation of cerebral hemody-namics using time-resolved projection MRA was stud-ied in normal volunteers and patients of cerebrovascu-lar diseases. Six normal volunteers and ten patients with cerebrovascular occlusive diseases including 6 of IC occlusion and 4 of post EC, IC bypass surgery un-derwent time-resolved projection MRA on a 1.5 T clinical MRI system. Projection angiograms are ac-quired with 2 D-fast SPGR sequence with a time reso-lution of approximately one image per second, 40 im ages being acquierd consecutively before and after bo-lus injection Gd-DTPA.
