Characterization of Adnexal Masses on Trans Abdominal Ultrasonography and CT scan

Objective: To cross validate the diagnostic performance of transabdominal ultrasound and computed tomography for discrimination of benign and malignant masses. Study Design: Comparative Cross sectional study. Place and Duration of Study: The study was conducted at department of Radiology from January 2008 to December 2008. Materials and Methods: The study was conducted in department of radiology from January 2008 to December 2008 .In this study 50 patients with adnexal masses admitted in Gynae MCH ,General Surgery wards of PIMS, scheduled for surgery, were included, using histopathology as a gold standard. Results: TAUS had sensitivity of 78%, specificity 88.8%, Positive predictive value of 85.7% and negative predictive value of 82.7 %. CT scan showed sensitivity of 91%, specificity of 81.4%, positive predictive value of 80.7% and negative predictive value of 91%. The comparison between two tests was statistically insignificant (p o.o5). Conclusion: Evaluation of adnexal masses whether benign or malignant on the basis of characterization there was not a significant difference between TAUS and CT scan. TAUS is as accurate as CT scan in characterization of an ovarian mass.
