During MCAO and at 24 hr and 7 days post-reperfusion, an magnetic resonance angiogram (MRA) sequence (TE = 3.8 ms, TR = 15 ms, matrix = 256 × 256, FOV = 4 × 4 mm, 50 contiguous coronal slices, 0.4 mm slice thickness, spatial resolution of...
If a subarachnoid hemorrhage is present, the cerebrospinal fluid that is obtained via the spinal tap will almost always have evidence of blood or blood products. In the case of spontaneous subarachnoid hemorrhages, a cerebral angiogram—an intravenous, catheter-based procedure—is the most useful tes...
