摘　　要：目的探讨基于中国数字化人体(CVH)和MRI对照,观察肩袖间隙(RI)薄层断面解剖特点,为临床应用提供影像解剖学依据。方法获取5个CVH肩关节解剖数据集,以斜冠状位、斜矢状位虚拟重建显示RI连续薄层断面解剖,并与20侧肩关节MR平扫T1WI,5侧肩关节MR造影(MRA)对照,用PhotoShop CS2软件观察RI。结果 3种显示方法中,CVH显示RI各边界最佳,优于MRI平扫T1WI和MRA。3个显示平面中,斜矢状位显示RI各边界结构及内容物最佳。在RI各边界显示中,其下界肩胛下肌腱、内界喙突在轴位、斜矢状位及斜冠状位3个平面中及CVH、平扫T1WI、MRA 3种显示方法中最易清楚显示。结论基于CVH的数据集研究RI边界及毗邻关系是较好的方法,以其斜矢状位显示肩袖间隙边界、内容物及毗邻关系为最佳,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 rotator interval （RI） through the comparative study of the thin sectional anatomy based on the Chinese Visible Human （CVH） and MRI sectional anatomy of the RI, 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 MR imaging, 5 shoulders without abnormalities with MR arthrography. The detailed sectional anatomy structure of the RI was marked from the CVH, routine MRI and MR arthrography one by one with Photoshop CS2 software. Results Among the three methods of depicting the RI, the CVH was the most suitable for evaluation of the borders of the RI and was better than MR T1WI and MR arthrography. Including axial, coronal oblique, and sagittal oblique plane, the sagittal oblique images was the most optimal for manifestation of the edges and components of RI. Both the inferior margin of the RI （the scapularis tendon） and the base of the RI （the coracoid process） were the most markedly displayed on the three methods （CVH, MR T1WI and MR arthrography）, and on the three of views （axial, coronal oblique, and sagittal oblique plane） of depicting the RI. Conclusion The CVH has been shown to be the imaging modality of choice for identifying the borders of the RI and its adjacency. The sagittal oblique plane is the best view for displaying the margins, the components and adjacent structures of the rotator interval, which provides helpful position mark for the diagnosis of the lesions in the rotator interval.
