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 investigate the anatomical characteristics of thin section of rotator cuff gap (RI) based on CVH and MRI in China and to provide anatomical basis for clinical application. Methods Five CVH shoulder anatomical data sets were acquired. The thin sections of RI continuous thin sections were reconstructed with virtual reconstruction of oblique coronal and oblique sagittal planes, and were compared with MR plain T1WI of 20 sides of shoulder, MRA of 5 sides of shoulder, In contrast, RI was observed with PhotoShop CS2 software. Results Of the three methods, CVH showed the best RI border, which was better than MRI plain T1WI and MRA. Among the three display planes, the oblique sagittal position shows the best structure and contents of each boundary of RI. In the RI border display, the lower boundary of the subscapularis tendon, the inner border of the coracoid in the axial, sagittal and oblique coronal 3 plane and CVH, plain T1WI, MRA most easily displayed the three kinds of display methods . Conclusions It is a good method to study RI border and adjacent relationship based on CVH dataset. The oblique sagittal display of the boundary, contents and adjacent relation of the rotator cuff gap is the best, which provides important information for the diagnosis of rotator cuff gap disease Identification mark.
