Diagnostic accuracy of diffusion weighted imaging on MRI in suspected cases of ovarian cancer, keeping histopathology as gold standard.

Abstract

Objective: To assess the diagnostic accuracy of diffusion weighted imaging on MRI in patients of ovarian cancer with histopathology considered as gold standard. Study Design: Cross-sectional study. Setting: Department of Radiology, Tertiary Care Hospital Kharian. Period: February 2022 to August 2022. Material & Methods: Non-probability, consecutive sampling was performed from 60 patients. After receiving informed consents, the suspected female patients with age 15 to 65 years went under MRI. The results were compared with histopathological findings and diagnostic potential of MRI was calculated by 2x2 table. The findings of both the modalities were compared by correlation analysis with p<0.05 considered as significant. Results: The sensitivity and specificity of MRI were estimated to be 92.68% and 73.68%. The positive predictive value and negative predictive value were estimated to be 88.37% and 82.35%. The diagnostic accuracy was found to be 86.66%. The findings of MRI and histopathology were significantly (p<0.05) correlated with a value of 0.685. Conclusion: The use of MRI is highly recommended in diagnosis of ovarian cancer.
