Benign versus malignant adnexal masses: Does addition of Color and Spectral Doppler over and above the Gray Scale Ultrasound improves diagnostic efficacy
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2016, Vol 4, Issue 1
Abstract
The present prospective study aimed at evaluating the relative value of Gray scale Ultrasound (US) alone and in combination with Color and Spectral Doppler in differentiating benign and malignant adnexal masses. Out of 122 adnexal masses in 106 patients (16 patients had bilateral adnexal masses), at histopathology 83 (68%) were benign and 39 (32%) were malignant. Gray scale US correctly diagnosed 74 adnexal masses (89.16%) as benign and 34 (87.18%) as malignant while Gray scale US combined with Color and Spectral Doppler correctly identified 79 adnexal masses (95.18%) as benign and 37 masses (94.88%) as malignant. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) in differentiating benign and malignant adnexal masses with Gray scale ultrasound alone was 89%, 87%, 94% and 79% respectively whereas when Gray scale ultrasound was combined with color and spectral doppler both sensitivity and specificity increased to 95%, PPV increased to 98% and NPV increased to 90%. Thus, Gray scale US combined with Color and Spectral Doppler is superior to Gray scale US alone in differentiating benign and malignant adnexal masses. So, we propose addition of Color and Spectral Doppler to Gray scale US in preoperative characterization of all adnexal masses in terms of benign and malignant, so as to establish more accurate and early definitive diagnosis, thereby guiding most appropriate intervention.
