Abstract:
PURPOSE: We assessed the usefulness of magnetic resonance angiography(MRA) and its techniques for differential diagnosis of hemorrhagic causes in patients with non-traumatic intracranial hemorrhagic disease. MATERIALS AND METHODS: We retrospectively reviewed 74 patients with non-traumatic intracranial hemorrhagic diseases, which were confirmed by radiological examinations(36 cases) and operations(38 cases). We compared the usefulness of magnetic resonance imaging(MRI) alone from MRI with MRA in evaluation of hemorrhagic causes. MRA was obtained by Time-of-Flight(TOF) and Phase Contrast(PC) technique. We investigated the usefulness of TOF and PC technique. RESULTS: MRI with MRA for detection of hemorrhagic causes(89%, 66 cases) was better than MRI only (64%, 47 cases). PC was better than TOF for evaluation of arteriovenous malformation and aneurysm due to subtraction of background noise(hemorrhage). CONCLUSION: MRI with MRA in more useful than MRI alone for evaluation of non-traumatic intracranial hemorrhagic causes.
