摘　　要：目的　初步探讨脑膜瘤术后的MRI表现及其临床意义。方法　对 8例脑膜瘤病人在术前和术后第 3天、第 7天、第 30天分别进行增强MRI检查。结果　 4例全切肿瘤病例中有 3例在术后第 3天、第 30天无强化病灶出现 ,而第 7天有不规则或不均匀强化 ;4例次全切或部分切除肿瘤病例均在术后第 3天、第 30天出现团块状强化 ;8例病例均在术后第 7天出现不规则或不均匀强化。结论　术后第 3天、第 7天MRI检查结果可作为判断脑膜瘤切除程度的客观标准 ,能克服术者主观判断的偏差 ,并能避免术后血肿、水肿、脑组织创伤、新生血管等因素对残存肿瘤影像的干扰。Objective To discuss postopcrative MRI expression and its clinical valuc. Method Eight patients with meningioma received MRI check before the operation and respectively on the 3rd, 7th and 30th day after the operation. Result No enhanced focus was found in the three of the total four cases who had received complete resection on the 3rd and 30th day after the operation. But on the 7th day, there was irregular enhancement. On the 3rd and 30th day after the operation, masslike enhancement appeared in four cases who had received partial resection. And on the 7th day, there was irregular enhancement in all eight cases. Conclusion The result of MRI check can be an objective criterion in judging the degree of the meningioma resection. In this way we can correct the errors we made by subjective judgement and avoid the influence on the imagination of redual tumor caused by hematoma, edema, traumatic and hyperplasia vessels.
