Role of MRI in staging of carcinoma cervix in correlation with USG and CT scan

Abstract

Background: Uterine cervical cancer is the most common gynecologic malignancy and the second most common cancer in women worldwide in terms of incidence and mortality. The present study was conducted to assess MR imaging staging in uterine cervical carcinoma. Materials & Methods: This study was conducted on 60 patients of neoplastic etiology involving endocervix. Patients were scanned on 1.5Tesla MRI Scanner. Contrast enhanced scans were performed wherever indicated. The contrast used in the study was Gadolinium-DTPA at the rate 0.1 ml mol/kg. MR characteristics of different sequences including the contrast-enhanced sequences were noted and recorded.Results: MRI showed high rate of detection (96.7 %) as compared to CT scan and USG with failure of detection only in lesion staged Ia1 or Ia2 which represents microscopic involvement of carcinoma of cervix. CT scan was able to detect nodes in 80 % cases. USG failed to demonstrate enlarged nodes in 6 cases. Maximum stage was IV seen in 21% followed by IIb in 20% and Ib2 in 16%. The difference was significant (P< 0.05).Conclusion: Authors found that MRI is highly sensitive in detection of early stage of carcinoma of cervix.
