【摘要】 目的 探讨多层螺旋CT(MSCT)在结直肠癌诊断中的价值。方法 回顾性分析经手术病理证实的42例结直肠癌MSCT资料,所有病例均做多平面重组(MPR),部分病例加做曲面重组(CPR)、表面遮盖法重组(SSD)、仿真结肠镜成像(CTVC)、透明重建(Raysum),将MSCT表现与手术和病理结果进行比较。结果 MSCT对结直肠癌的检出率为100%,定性准确率100%;对肿瘤向邻近组织侵犯诊断准确率为82.9%(29/35),腹部脏器转移诊断准确率为100%(7/7),淋巴结转移诊断敏感性为71%(22/31)而特异性为100%。结论 MSCT扫描结合多种重建技术能明确结直肠癌的诊断,对临床治疗有指导作用。更多还原

【Abstract】 Objective To investigate the value of multi-slice spiral CT(MSCT) in diagnosis of colorectal carcinoma.Methods MSCT images of 42 cases of colorectal carcinoma proved by surgery and pathology were retrospectively analyzed.Multiplanar reconstruction(MPR) in all cases,and curved planar reconstruction(CPR),shaded surface display(SSD),CT virtual colonoscopy(CTVC) and Raysum were performed in some of the cases.MSCT findings were analyzed in comparison with operative and pathologic features.Results The detecting rate and quatitative rate of colorectal carcinomas with MSCT were 100% respectively.The accurate rates were 82.9%(29/35) and 100%(7/7) in detection of invasion of surrounding structures and metastasis in abdominal organs respectively,the sensitivity and specificity for detetion of lymph node metastasis were 71%(22/31) and 100% with MSCT imaging.Conclusion MSCT scan with multiform reconstruction techniques can make definite diagnosis of colorectal carcinoma,which is helpful for treatment plan.更多还原
