MR Angiography of Ruptured Aneurysms in Acute Subarachnoid Hemorrhage AJNR 18:1025-1032, Ida,M.,et al, 1997 See this aricle in Pubmed Article Abstract Thirty-five(90%)of 39 aneurysms were detected prospectively with MR angiography.At least one aneurysm was identified with MR angiography in 25 (96%)of 26 patients with aneurysms proved by IA-DSA.Although four aneurysms were missed prospectively,three of these were detected retrospectively with MR angiography.Six aneurysms(18%)of those evident on MR angiograms were 3 mm or less in diameter.In one patient,additional targeted maximum intensity projections were greatly helpful for the ensuing IA-DSA by determining the optimizal projection angle by which to depict a ruptured aneurysm that neither routine MR angiography nor routine IA-DSA detected.High-resolution MR angiography may be a useful diagnostic technique for detecting ruptured aneurysms,even in patients with acute subarachnoid hemorrhage.Initial MR angiography offers valuable and reliable information on ruptured aneurysms in acute subarachnoid hemorrhage,allowing the optimization of projection angles at conventional angiography.
