Nine patients with cerebral or cerebellar hemispheric infarction and two patients with brain stem lesions were studied with NMR imaging in order to examine the lesion with different weightings on the various NMR parameters. The time interval between examination and the acute onset of the stroke varied from one day to six months. The lesions were clearly detected by the T1 weighted inversion recovery sequence but the tissue contrast was better using the spin echo sequence with a long repetition rate and a long echo delay (SE2000/100). In two patients the brain stem lesions were invisible with CT, but were easily depicted with NMR. In one of them the further progress of the lesion was also confirmed and visualized with the follow-up NMR study.
对9例大脑或小脑半球梗死患者以及2例脑干病变患者进行了核磁共振成像研究，以便在不同的核磁共振参数下以不同权重检查病变。检查与中风急性发作之间的时间间隔从1天到6个月不等。T1加权反转恢复序列能清晰检测到病变，但使用长重复率和长回波延迟的自旋回波序列（SE2000/100）时组织对比度更好。2例患者的脑干病变在CT上不可见，但在核磁共振成像上很容易显示。其中1例患者病变的进一步发展也通过核磁共振成像随访研究得到证实并可视化。
