摘　　要：目的评价多层螺旋CT(MDCT)及多平面重建(MPR)在胆囊癌术前T分期中的作用。方法回顾118例经病理证实的胆囊癌患者门脉期MDCT扫描的轴位图像,分析53例的轴位和MPR图像,并将结果与McNemar检验的病理结果进行比较,评价MDCT对不同T分期的鉴别能力。结果鉴别≤T1与≥T2、≤T2与≥T3、≤T3与T4病变的敏感性分别为79.3%、92.7%和100%,特异性分别为98.8%、86%和100%(P<0.0001)。T分期的总准确率为83.9%。在53例MPR图像中,轴位和MPR图像的联合读数使诊断准确率从71.7%提高到84.9%,差异有统计学意义(P=0.0233)。结论多层螺旋CT对胆囊癌局部范围的诊断具有较好的敏感性和特异性,将MPR图像添加到轴位CT数据中提高了准确性。Objective To evaluate the role of multi-slice spiral CT(MDCT)and multiplanar reconstruction(MPR)in preoperative T staging of gallbladder cancer.MethodsThe axial images of 118 pathologically confirmed patients with gallbladder cancer at portal stage were reviewed,and the axial and MPR images of 53 cases were analyzed.The results were compared with the pathological results of McNemar test to evaluate the differential ability of MDCT for different T stages.ResultsThe sensitivities of≤T1 and≥T2,≤T2 and≥T3,≤T3 and T4 were 79.3%,92.7%and 100%,and the specificities were 98.8%,86%and 100%,respectively(P<0.0001).The total accuracy of T stage was 83.9%.In 53 MPR images,the diagnostic accuracy was increased from 71.7%to 84.9%by the combination of axial position and MPR images,the difference was statistically significant(P=0.0233).ConclusionMulti-slice spiral CT has good sensitivity and specificity in the local diagnosis of gallbladder cancer.Adding MPR images to axial CT data improves the accuracy.
