Aim: To compare modalities like ultrasonography (USG) and computed tomography (CT) in the evaluation of suspicious ovarian masses. Methodology: This prospective comparative study was carried out in the Department of Radiology, Maharishi Markandeshwar Institute of Medical Sciences and Research, Mullana for a period of 1-year 3 months. Total 50 women were included in this prospective study. All patients underwent abdominal Ultrasonography and CT scan with determination of the ovarian mass characteristics. Detailed history of allergy and renal function tests were taken before doing CT scan and if there was history of allergy then non-ionic contrast was used. Site, size, papillary projections, wall characteristics, capsular infiltrations, the presence of solid areas inside the mass and presence of ascites were recorded both by US and CT scan.
