儿童戈谢病累及股骨和膝关节的MRI表现
Chinese Journal of Medical Imaging Technology(2012)
Abstract
目的 观察戈谢病儿童股骨和膝关节的MRI表现.方法 39例戈谢病患儿接受3.0T MR检查,包括冠状位T1W、T2W、STIR序列,检查部位为双侧股骨包括膝关节,分析和描述其MRI特点.结果 38例发现骨髓浸润,其中32例表现为稍长T1稍短T2信号;28例T1WI、T2WI骨髓腔信号不均匀减低,4例信号弥漫均匀减低;6例伴骨梗死.16例骨干、干骺端及骨骺同时受累;18例骨干及干骺端受累;单纯累及骨干或干骺端者各2例.结论 儿童戈谢病骨髓浸润MRI表现具有一定特征性,综合不同序列MR图像的信号特点,可评估骨髓浸润范围、判断是否伴发合并症,为临床治疗提供信息.
