Hitherto T1-weighted Spin-Echo-Sequences, most combined with T2-weighted sequences, were used to detect pathological bone marrow lesions. This method needs a long examination time and results in T2-images with a low morphological resolution. In the majority of examinations using Gradient-Echo-Sequences with prolonged repetition-times (FLASH: flip angle 40 degrees, TR/TE = 500/17 msec) there is no need of an additional measurement. Therefore these sequences save about 75% of the examination time and they give higher contrast between normal and pathological bone marrow.
迄今为止，T1加权自旋回波序列大多与T2加权序列结合使用，用于检测病理性骨髓病变。这种方法需要较长的检查时间，并且得到的T2图像形态分辨率较低。在大多数使用具有延长重复时间的梯度回波序列（FLASH：翻转角40度，TR/TE = 500/17毫秒）的检查中，无需进行额外测量。因此，这些序列可节省约75%的检查时间，并且能在正常和病理性骨髓之间提供更高的对比度。
