In one year, cerebral angiograms were performed for intracranial haemorrhage (ICH) on 334 patients. No cause for haemorrhage could be identified in 41 (12%), 30 of whom had predominantly subarachnoid (SAH) and 11 predominantly parenchymal haemorrhage (PH). These patients were prospectively examined by cranial MRI 1-6 weeks after the ictus. The MRI studies were positive in 7 patients (17%). In the 30 patients examined after SAH, 2 studies were positive, showing an aneurysm in one case and a brain stem lesion of uncertain aetiology in the other. In those examined after PH, cavernous angiomas were shown in 2, a tumour in 1 and a vascular malformation in another; useful diagnostic information was thus obtained in 36% of this group.
在一年时间里，对334例颅内出血（ICH）患者进行了脑血管造影。41例（12%）患者未发现出血原因，其中30例主要为蛛网膜下腔出血（SAH），11例主要为实质内出血（PH）。这些患者在发病后1 - 6周接受了头颅MRI的前瞻性检查。MRI检查在7例患者（17%）中呈阳性。在30例SAH后接受检查的患者中，2例检查呈阳性，1例显示为动脉瘤，另1例显示为病因不明的脑干病变。在PH后接受检查的患者中，2例显示为海绵状血管瘤，1例为肿瘤，另1例为血管畸形；因此，该组中有36%的患者获得了有用的诊断信息。
