摘要
目的：回顾分析我院46例急性脑干梗死磁共振影像学特点，探讨常规MRI及DWI对急性脑干梗死早期诊断的临床价值。方法：46例均行CT扫描，45例行常规MRI及DWI扫描，1例行DWI扫描。结果：30例为脑干单发病灶，16例合并其他部位梗死。46例中中脑33例，桥脑10例，延髓3例，超急性期（〈6小时）7例。急性期（6～24小时）8例。亚急性期（〉72小时）21例，常规MRI显示各期信号特点不同，DWI序列上病灶均显示不同强度高信号。结论：常规MRI结合DWI不仅使脑干梗死得到早期诊断，并可对梗死恢复情况做出准确判断，为临床治疗提供可靠依据。
Objective：Retrospective analysis of 46 patients with brainstem infarction in magnetic resonance imaging characteristics, ex- plore routine MRI and DWI for aclae brain stem infarction can the clinical value of early diagnosis. Methods：46 patients were performed CT scanning, 45 routine MRI and DWI scans, can 1 DWI scan can routine. Results ：30 cases of brain stem single lesions, 16 cases with other parts of the infarction. 46 cases in the midbrain 33 cases, 10 cases of brain bridge, medulla oblongata （3 cases）, super acute peri- od （ 〈 6 hours） 7 cases. 8 cases of acute period （6 to 24 hours）. Subacute stage （ 〉 72 hours） 21 cases, conventional MR/ signal characteristics are different, every period lesions are on DWI sequence can show different high signal intensity. Conclusion： Conventional MRI combined with DWI not only can make for early diagnosis of brainstem infarction, and can make a accurate judgment to the infarct recovery, to provide reliable basis for clinical treatment.
