Abstract:
To assess the effectiveness of Magnetic Resonance Imaging (MRI) with endorectal surface coil in the ataging of carcinoma of the uterine cervix with emphasis on parametrial involvement. Thirty women with clinically and radiographically proven carcinoma of the uterine cervix were initially included for this study, but thirteen patients were excluded since the stages of tumors wore beyond stage IIa. CT and MR findings of the remaining seventeen patients were performed at Cheil General Hospital and compared a1ong with clinical findings with the special emphasis on the parametrial involvement by the tumor. Staging was assessed by CT and MRI, and the results were compared with the pathologic staging. Radiea1 abdominal hysterectomy with the pelvic and paraaortic lymphnode dissection was done to all sewenteen patients. The staging made primarily by CT and MRI was either stsge 1 or Ila, but MR images with endorectal surface coil was superior to CT in the visualization of depth of tumor infiltration, especially parametrial involvement. The determination of the depth of the tumor made by MR images showed statistically significant correlation with histologic evaluation(R =0.768, p<0.01). The accuracy rate for the evaluation of the parametrial invo1vement was 82.3% far CT and 94.1% for MRI with endorectal surface coil. The overall accuracy rate for tumor staging was 70.5% for clinical, 58.8% for CT and 82.3% for MR evaluation. The accurecy rate in evaluation of the pelvic and paraaortic lymphnode was 88.2% for CT, but the evaluation done by MRl was not adequate due to small FOV(field of view). In assessment of The steging of careinoma of the uterine cervlx, MR images with endorectal surface coil was superior to CT, especially in the evaluation of the parametrial involvement.
