Positive Predictive Value of Ultrasonography for Detection of Ovarian Masses Taking Magnetic Resonance Imaging as a Gold Standard

Aim: To determine the efficacy of ultrasonography in detection ovarian masses considering MRI a Gold standard. Study design: Prospective analytical cross-sectional study Place and duration study: Dow Institute Radiology, University Health Sciences Karachi, Pakistan from 1st June 2018 to 30th November 2019. Methodology: One hundred forty eight cancer patients were enrolled. Results: The mean age patient was 41.87±16.30 years. majority ≥20 years (29.10%) obese (33.1%). Malignant tumors 56.1% (n=83) 64.2% (n=95) respectively on ultrasound magnetic resonance imaging. Ultrasound had positive predictive value 80%, sensitivity 98.11%, specificity 86.32 % for diagnosis masses. Overall diagnostic accuracy 90.54%. There an excellent agreement between imaging (kappa=0.84, p-value <0.001) area under curve 92.2%. Conclusion: Ultrasonography has Keywords: Ovarian mass/tumor, Ultrasonography, MRI, Positive value, Benign,
