The authors report their experience with magnetic resonance imaging (MR) in 20 patients with CT-proved lymphadenopathy of the abdomen and pelvis. Signal intensity from abnormal nodes was intermediate between fat and muscle (T1 longer than fat and muscle; T2 equal to or slightly shorter than fat but longer than muscle) and was shown best in the spin-echo mode with a TR of 900 msec. and a TE of 30 msec. Abnormal nodes were identified by their increased size and other morphological changes rather than by tissue characteristics established by signal intensity information. Lymphadenopathy due to lymphoma could not be differentiated from that due to metastases. MR detected all lymphadenopathy originally documented by CT and in addition easily distinguished blood vessels from lymph nodes; on the other hand, CT offered better spatial resolution and could be completed in less time.
作者报告了他们对20例经CT证实有腹部和盆腔淋巴结病患者进行磁共振成像（MR）检查的经验。异常淋巴结的信号强度介于脂肪和肌肉之间（T1长于脂肪和肌肉；T2等于或略短于脂肪但长于肌肉），在TR为900毫秒、TE为30毫秒的自旋回波模式下显示最佳。异常淋巴结通过其增大的尺寸和其他形态学改变得以识别，而非通过信号强度信息所确定的组织特征。淋巴瘤所致的淋巴结病无法与转移瘤所致的淋巴结病相鉴别。MR检测出了所有最初由CT记录的淋巴结病，此外还能轻松将血管与淋巴结区分开来；另一方面，CT具有更好的空间分辨率，且能在更短时间内完成检查。
