本文对经MRI确诊的85例脑卒中急性期患者的磁共振血管成像(MRA)资料进行了分析。MRA显示脑内血管形态异常者58例(68.2%),其中脑梗塞组47例(71.2%),比传统的血管造影术显影率高。脑卒中急性期脑血管成像表现为4种类型:①完全闭塞;②不完全闭塞;③血管稀少、血流减慢;④血管移位变形。脑梗塞组以①、②型表现者占91.7%,而脑出血组则以④型为主要表现形式。

对11例手术病理证实的椎管内肿瘤进行磁共振成像(MRI)增强扫描的前、后分析,并对肿瘤定位、定性和鉴别诊断作了初步探讨。根据肿瘤形态、边界、强化程度,及与脊髓、硬脊膜、神经根等关系,MRI的增强扫描对提高其定位、定性诊断均有较大的帮助。
