Value of Multislice Spiral CT in Evaluating Parametrial Invasion of Cervical Carcinoma / 医疗卫生装备

ABSTRACT

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.
