Objective To compare CT perfusion imaging staging and FIGO staging and pathological staging of cervical carcinoma. Methods 148 patients with cervical carcinoma were scanned with GE Lightspeed UItra 16 slice spiral CT scanner. The images were transmitted to the PACE system and were processed by multi planar reconstruction (MPR) to obtain coronal, sagittal and oblique coronal images. The differences of CT staging, FIGO staging and postoperative pathological staging were compared. Results CT staging diagnosis of 148 patients with cervical carcinoma showed 27 cases of stageⅠa, 41 cases of stageⅠb, 28 cases of stageⅡa, 18 cases of stageⅡb and 6 cases of stageⅢa. Staging was correct in 120 cases, accounting for 81.08%, in which CT and FIGO staging showing no lesions in7 cases. The rate of missed diagnosis was 4.73% which was detected by postoperative exfoliative cytology. CT diagnosed excessive low staging in 8 cases, accounting for 5.41% and excessive high staging in 20 cases, accounting for 13.51%. For FIGO staging, there was excessive low staging in 31 cases and excessive high staging in 28 cases. The diagnostic accuracy was 60.14%. Conclusion The accurate rate of CT perfusion imaging staging is higher than that of FIGO staging and it can provide more information. It can be used as an error correction test after FIGO staging. CT is of important guiding significance in preoperative staging, the selection of operation scheme and prognosis.
