Diagnostic Accuracy of 16 Slice Contrast Enhanced CT Scan for Detection of Malignancy in Patients with Complex Adnexal Masses on Ultrasonography (Taking Histopathology as Gold Standard)

Abstract

Objective: To determine the diagnostic accuracy of a 16-slice contrast-enhanced CT scan (CECT) for the detection of malignancy in patients with complex adnexal masses on Ultrasonography (USG) (taking histopathology as the gold standard).

Study Design: Cross-sectional study.

Place and Duration of Study: Pakistan Naval Ship Shifa Hospital, Karachi Pakistan, from Jul to Dec 2020.

Methodology: Seventy-five patients with adnexal masses were included. All patients had 16-slice contrast-enhanced CT scans. All the patients then had exploratory laparotomy, followed by histopathology as the gold standard. The diagnostic accuracy of CECT (contrast-enhanced computed tomography) was detected by determining sensitivity, specificity and diagnostic accuracy.

Results: 16-slice contrast-enhanced computed tomography showed a sensitivity of 92.2%, specificity of 93.4%, and diagnostic accuracy of 93.1%.for correctly diagnosing adnexal malignancy.

Conclusion: Due to its high sensitivity, specificity and diagnostic accuracy, 16 slice contrast-enhanced CT scan is a reliable test for diagnosing malignancy among patients with unexplained adnexal masses on USG.
