AbstractAim: 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, RVM Institute of Medical Sciences & Research Centre for a period of 15 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 as cites were recorded both by US and CT scan.
Results: Out of 50 patients, majority of patients belonged to 40-50 years of age group (19, 38%) followed by 30-40 years of age group (10, 20%). 8 patients (16%) belonged to 20-30 years age group, 7 (14%) belonged to 50-60 years, <20 and >60 years of age group included 3 patients each. There are total 29 cases of Pre-menopausal stage and 21 cases of Post-menopausal stage having ovarian cyst. Out of 29 cases of pre-menopausal conditions have 7 number of malignant and 22 number of benign types of ovarian masses. In the Postmenopausal group there are 17 cases of malignant and 4 cases of benign ovarian mass was observed. Overall, CT was found to have 96% sensitivity, 92% specificity, and an accuracy of 92% in the differentiation of benign and malignant ovarian masses, while PPV and NPV were 94% and 90%, respectively. The sensitivity of USG was 90%, specificity was 86% and PPV and NPV were 88% and 86% respectively.
Conclusion: CT and USG imaging all have approximately similar accuracy in staging ovarian carcinoma but the sensitivity of CT scan for all ovarian cancer detection greater than that of US. Among women with ovarian disorders, CT can be primarily in patients with ovarian malignancies, either to assess disease extent prior to surgery or as a substitute for second look laparotomy.
