Abstract
A multiple spin-echo-sequence has been evaluated in diagnosis of demyelinating diseases. TE in these MR-experiments was between 14 and 336 msec, TR between 860 and 1660 msec. Three groups of patients were examined, and it could be shown that the probability to detect MS-plaques grows with long TE's up to 300 msec. T2-relaxation-time-values range between 126 and 250 msec. Different MS-plaques in the same patient might show different T2-values.
摘要
一种多自旋回波序列已被用于脱髓鞘疾病的诊断评估。在这些磁共振实验中，回波时间（TE）在14至336毫秒之间，重复时间（TR）在860至1660毫秒之间。对三组患者进行了检查，结果表明，检测到多发性硬化斑块的概率随着长达300毫秒的长TE而增加。T2弛豫时间值在126至250毫秒之间。同一患者体内不同的多发性硬化斑块可能显示出不同的T2值。
