多层螺旋CT在评价宫颈癌宫旁侵犯的价值

目的：探讨多层螺旋CT扫描在评价宫旁侵犯中的价值。方法：收集75例接受手术治疗的Ⅱ期宫颈癌患者，对其CT影像学表现和FIGO分期进行回顾性分析。结果：FIGO分期判断宫旁侵犯的准确性达53.3％（40／75）．过低判断率为26．7％（20／75），过高判断率为20．0％（15/75）；CT判断宫旁侵犯的准确性为69.3％（52／75）。过低判断率为14．7％（11/75），过高判断率为17.3％（13/75）。FIGO分期和CT判断结果均与手术判断结果一致者40例，FIGO分期判断结果与手术判断结果不一致者35例．CT判断结果与手术判断结果不一致者29例．CT纠正FIGO分期判断结果者10例。结论：多层螺旋CT可以多平面成像，在判断宫颈癌宫旁侵犯方面比FIGO分期准确、直观。是FIGO分期的一个重要补充。

Value of Multislice Spiral CT in Evaluating Parametrial Invasion of Cervical Carcinoma

Objective To investigate the value of multislice spiral CT in evaluating the parametrial invasion of cervical carcinoma. Methods 75 cases of FIGO staging II cervical carcinoma who had received the surgery were studied. Their imaging and the FIGO staging were analyzed retrospectively. Results For FIGO staging, the accuracy for evaluating the parametrial invasion was 53.3%(40/75), the rate of underestimation was 26.7%(20/75), the rate of overestimation was 20.0%(15/75); For CT, the accuracy of evaluating the parametrial invasion was 69.3%(52/75), the rate of underestimation was 14.7%(11/75), the rate of overestimation was 17.3%(13/75). In 40 cases, both FIGO staging and evaluation by CT were consistent with the surgical results. In 35 cases, FIGO staging was different from the surgical results. In 29 cases, evaluation by CT was different from the surgical results. In 10 cases, CT could correct the error of FIGO staging. Conclusion CT scan can acquire the multi-plane image, and can directly reflect the parametrial space. It is more accurate than FIGO staging, and is an important complement to FIGO staging.
