1. Parametrial invasion의 overall accuracy는 CT scan이 71.2%, clinical staging이 88.7%였다. 2. CT scan의 임파절 전이의 진단에 있어서는 sensitivity가 14.3%, specificity가 76.1%였다. 3. CT scan상 Stage IIb이상의 15명의 분석에서 conization이나 previous cesarean section이 10례 로 66.7%를 차지하여 false(+)의 주도 원인이었다. 4. Cone biopsy나 cesarean section의 기왕력을 지닌 18례의 환자에서 CT scan상 parametrial invasion 진단에 있어 false(+)율은 55.6%였다.

Fifty-three consecutive patients with primary carcinoma of cervix were evaluated by computed tomography (CT) to assess CTs ability to screen patients prior to radical surgery. CT staging results were compared with those of clinical staging and pathologic staging in 53 radical hysterectomy with paraortic and pelvic lymph nodes dissection under the impression of early carcinoma of the cervix. The overall accuracy of parametrial invasion by CT scan is 71.2%, and by clinical staging is 88.7%. And CT sensitivity in diagnosis of lymph node metastasis is 14.3%, and CT specificity is 76.1%. In the analysis of false positive parametrial invasion in 15 cases (over Stage IIb) by CT scan. Inflammatory reaction caused by conization of cervix and Cesarean section account for 66.7% in all false positive parametrial invasion cases. And the rate of false positive parametrial invasion by CT scan in 18 cases following cone biopsy or Cesarean section is 55.6%. Though there is some difficulty in assessing parametrial fibrosis and micronodal metastasis. We concluded that CT scan can serve as a sensitive imaging modality to assess the surgical candidacy of patients with primary carcinoma of the cervix.
