Abstract

PURPOSE

To determine the contribution of cranial MR angiography (MRA) for the evaluation of patients with acute and subacute brain infarction.

METHODS

MR and MRA studies performed on 78 adult patients with acute and subacute stroke were retrospectively reviewed and correlated with the clinical records.

RESULTS

There were 50 acute and 28 subacute infarctions in our series. Five of 78 MRA exams (6%) were nondiagnostic. Sixty examinations (80%) were positive for stenosis or occlusion. The distribution of stenotic or occlusive vascular lesions correlated with the location of infarction in 56 of the 60 positive cases (93%). MRA provided information not obtained from the MR images in 40 cases (55%). One hundred four individual vessels in 8 patients who underwent conventional cerebral angiography were compared with the MRA appearance. The MRA interpretations correlated with the conventional angiographic evaluations for 90 vessels (87%).

CONCLUSIONS

Vascular lesions demonstrated on intracranial MRA show a high correlation with infarct distribution. MRA provides information adjunctive to conventional MR in a majority of cases. We conclude that MRA is an important component of the complete evaluation of brain infarction.

摘要

目的

确定头颅磁共振血管造影（MRA）在评估急性和亚急性脑梗死患者中的作用。

方法

对78例急性和亚急性脑卒中成年患者进行的磁共振成像（MR）和MRA研究进行回顾性分析，并与临床记录进行对照。

结果

本研究系列中有50例急性梗死和28例亚急性梗死。78例MRA检查中有5例（6%）诊断不明确。60例（80%）检查显示有狭窄或闭塞。60例阳性病例中有56例（93%）狭窄或闭塞性血管病变的分布与梗死部位相关。MRA在40例（55%）病例中提供了从MR图像未获得的信息。对8例行传统脑血管造影患者的104条血管的MRA表现与传统血管造影评估结果进行了比较。MRA解释与90条血管（87%）的传统血管造影评估结果相关。
