目的探讨多层螺旋CT肩关节斜冠状位多平面重组(multiplanar reformation,MPR)的方法及其应用价值。资料与方法20例(40侧)经16层螺旋CT常规容积扫描及薄层重组的肩关节病例,均应用常规MPR(CM-PR)、多向调整MPR(AMPR)及旋转式MPR(RMPR)技术对肩关节进行斜冠状位重组。由两名有经验的CT诊断医师对所有重组图像进行对比分析。结果40侧肩关节中,3种MPR技术均获得了斜冠状位图像。在显示肩关节图像质量方面,AMPR与RMPR模式优于CMPR模式(A医师:UAMPR∶CMPR=-7.221,P=0.000,URMPR∶CMPR=-7.629,P=0.000;B医师:UAMPR∶CMPR=-5.510,P=0.000,URMPR∶CMPR=-6.686,P=0.000),AMPR与RMPR模式无差异(A医师:UAMPR∶RMPR=-0.872,P=0.383;B医师:UAMPR∶RMPR=-1.291,P=0.197)。在肩关节成像的简易程度方面,RMPR技术优于AMPR技术(tA=37.267,tB=36.236,P=0.000)。结论AMPR、RMPR均能获得肩关节的标准斜冠状位图像,在评价肩关节疾患方面较CMPR更具优势和应用价值,而RMPR较AMPR操作简便,是对肩关节MPR成像的一种新方法,值得推广应用。
Objective To investigate the method and application value of multiplanar reformation (MPR) of multi-slice spiral CT scleral coronal joints. Materials and Methods Twenty patients (40 sides) underwent routine volume scanning and thin layer reconstruction of 16 cases of spiral CT with conventional MPR (CM-PR), multi-directional adjustment of MPR (AMPR) and rotary MPR (RMPR) Technique of oblique shoulder coronal reorganization of the shoulder joint. A comparative analysis of all the reconstructed images was conducted by two experienced CT physicians. Results Among the 40 lateral shoulders, all three kinds of MPR techniques acquired oblique coronal images. The AMPR and RMPR patterns outperformed the CMPR pattern in displaying shoulder joint image quality (Doctor A: UAMPR: CMPR = -7.221, P = 0.000, URMPR: CMPR = -7.629, P = 0.000; B physician: UAMPR: (A physician: UAMPR: RMPR = -0.872, P = 0.383; B physician: UAMPR: RMPR = -1.291, P = 0.197). RMPR was superior to AMPR in terms of the convenience of shoulder arthroplasty (tA = 37.267, tB = 36.236, P = 0.000). Conclusions AMPR and RMPR can both acquire standard oblique coronal images of shoulder joint. Compared with CMPR, RMPR is more advantageous and valuable in evaluating shoulder joint disease. RMPR is more convenient than AMPR and is a new method for MPR imaging of shoulder joint. Worth promoting application.
