COMPARATIVE STUDY OF USG B-MODE AND DOPPLER IN EVALUATION OF OVARIAN MASS LESIONS

Abstract

Background: Ovarian cancer is highly lethal due to delayed detection. Ovarian lesions display a myriad of findings on imaging. Knowledge of these is essential to make a diagnosis or list the differentials. USG remains the mainstay imaging modality in this war on cancer. Aims & Objectives: To assess the diagnostic accuracy of USG B-mode and doppler in characterisation of ovarian mass lesions. Methods: 103 women with ovarian lesions were evaluated with USG B-mode and doppler. The interpretation was compared with histopathology reports wherever possible. Results: With sensitivity and NPV of 81.82% and 84.62% of USG B-mode, it is a good primary imaging modality. By showing an increase in specificity to 94.23%, PPV to 89.29% and accuracy to 87.06%, the addition of doppler in the evaluation acts as a tool in confirmation of malignancy. Conclusion: With good diagnostic performance, USG proves to be a good primary imaging modality. Also, doppler evaluation forms a promising add-on that can be considered.
