摘　　要：目的基于中国数字化人体(CVH)和MRI对照,观察肱二头肌长头腱(LBT)滑轮系统薄层断面解剖特点,为临床应用提供影像解剖学依据。方法 CVH肩关节解剖数据集5例斜冠状位、斜矢状位虚拟重建显示肱二头肌长头腱滑轮系统薄层断面解剖,并与20侧肩关节MRI平扫(T1WI),5侧肩关节MRI造影(MRA)对照,用Photoshop CS2软件观察LBT滑轮系统。结果LBT滑轮系统的主要结构喙肱韧带(CHL)、盂肱上韧带(SGHL)、肱二头肌长头腱(LBT)在MRI和CVH上显示清楚。CHL在T1WI斜矢状位显示最佳,SGHL在CVH横断面显示最佳,LBT在CVH上平行于LBT的斜冠状位显示最佳。LBT滑轮系统以斜矢状位CVH和MRA显示最佳,SGHL和CHL大致垂直,在LBT前方形成呈"T"分布的毗邻关系。结论 CVH和MRI显示LBT滑轮系统有很好互补性,以斜矢状位显示肱二头肌长头腱滑轮系统内部结构及毗邻关系为佳,为肩袖间隙疾病影像诊断提供了重要的识别标志。Objective To explore the morphologic features of the biceps reflection pulley through the comparative study of the thin sectional anatomy based on the Chinese Visible Human（ CVH） and MRI sectional anatomy of the biceps reflection pulley,and to provide imaging anatomic data for the diagnosis of lesions. Methods The thin slices of sagittal oblique plane and coronal oblique plane by visualizational reconstruction based on 5 data set of the Chinese visible human（ CVH） were compared with the corresponding MR images from 20 shoulder joints of the normal volunteer individuals with routine MRI,5 shoulders without abnormalities with MR arthrography. The detailed sectional anatomy structure of the the biceps reflection pulley was marked from the CVH,routine MRI and MR arthrography one by one with Photoshop CS2 software. Results The main three components of the biceps reflection pulley including the coracohumeral ligament（ CHL）,the superior glenohumeral ligament（ SGHL）,and the long head of the biceps tendon（ LBT） were markedly displayed on the CVH and MRI. The CHL was markedly displayed on the sagittal oblique,using plain MRI. The SGHL was markedly displayed on the CVH,especially in the transverse plane. The LBT was markedly displayed on the CVH,especially in the coronal oblique plane parallel to the LBT. The biceps reflection pulley was markedly displayed on the sagittal oblique plane with CVH and MR arthrography. The SGHL was perpendicular to the CHL,with Tshaped link anterior to the LBT on the sagittal oblique plane. Conclusion It is complementary for MRI and CVH displaying the components of the biceps reflection pulley. The sagittal oblique plane is the best position for displaying the components and adjacent structures of the biceps reflection pulley,which provide helpful position mark for the diagnosis of the lesions in the rotator interval.
