CT scans of muscles in patients with LG, MYD and DMD were obtained at five different body levels: the neck, L3 vertebral body, pelvic girdle, thigh and lower leg. CT numbers, cross sectional areas (CSA) and %CSA of muscle or fat were evaluated in each muscle. The characteristic CT patterns for each type of muscular dystrophy were obtained. Compared with DMD, the gracilis and soleus were more severely damaged in LG and the biceps femoris remained relatively preserved among the hamstrings. In addition, the multifidus of the neck and sternocleidomastoid also were more severely damaged in MYD. This study suggests that CT scan will be useful in the differential diagnosis of these types of muscular dystrophy as well as in planning appropriate rehabilitation and detecting damaged muscles.
对患有肢带型肌营养不良（LG）、先天性肌营养不良（MYD）和杜氏肌营养不良（DMD）的患者，在五个不同身体部位进行了肌肉CT扫描：颈部、第三腰椎椎体、骨盆带、大腿和小腿。对每块肌肉的CT值、横截面积（CSA）以及肌肉或脂肪的CSA百分比进行了评估。获得了每种类型肌营养不良的特征性CT图像。与DMD相比，LG患者的股薄肌和比目鱼肌受损更严重，而股二头肌在腘绳肌中相对保留较好。此外，MYD患者颈部的多裂肌和胸锁乳突肌也受损更严重。本研究表明，CT扫描在这些类型肌营养不良的鉴别诊断、制定适当的康复计划以及检测受损肌肉方面将是有用的。
