Fifty-one patients with 59 angiographically proven cerebral arteriovenous malformations (AVMs) were examined by high-field MRI to detect blood breakdown products. Results were correlated with the history of intracranial bleeding. Evidence of previous episodes of haemorrhage was seen in 10 of 12 patients (83.3%) with verified bleeding, in 4 of 9 patients (44.4%) with symptoms which could suggest bleeding and in 6 of 30 patients (20%) with negative histories. Because of the known rebleeding rate and the increased risk of associated complications, identification of the subgroup who had had haemorrhage and should therefore be considered for surgery may be beneficial. MRI can make a contribution to management by demonstrating prior haemorrhage in patients with an inadequate clinical history.
对51例经血管造影证实患有59处脑动静脉畸形（AVM）的患者进行了高场强MRI检查，以检测血液分解产物。将结果与颅内出血病史相关联。在12例经证实有出血的患者中，10例（83.3%）有既往出血发作的证据；在9例有提示出血症状的患者中，4例（44.4%）有此证据；在30例无出血病史的患者中，6例（20%）有此证据。鉴于已知的再出血率以及相关并发症风险的增加，识别出过出血且因此应考虑手术的亚组患者可能是有益的。MRI可通过在临床病史不充分的患者中显示既往出血情况，为治疗提供帮助。
