MRI assessment of ovarian masses and correlating with CA-125.

Background: The combined use of appropriate imaging modalities and serum biomarkers like serum Carcinoembryonic Antigen-125 (CA-125) helps plan treatment strategies and reduce overall mortality.

Aims And Objectives: To assess ovarian masses on Magnetic Resonance Imaging (MRI) and correlate them with serum CA-125 values. To derive a new serum CA-125 cut-off value for differentiating benign from malignant ovarian masses.
