Background: Magnetic resonance (MR) diffusion-weighted imaging (DWI) use will help in better characterization of ovarian tumors. The effect of gadolinium contrast agents on ADC measurements is not very well understood. More information is needed to standardize MRI protocols by determining whether performing DWI prior to or after dynamic contrast imaging (DCE) MRI makes a difference for evaluation of ovarian tumors Settings and design: Prospective Study done on 36 patients selected based on universal sampling, at KVG Medical College and Hospital, Sullia with Study population being women with newly diagnosed ovarian tumors who underwent CEMRI study to evaluate the nature of tumor and extent. Results: In benign and malignant ovarian tumors, Pre contrast mean ADC was comparable to Post contrast mean ADC value and with statistically insignificant P value. The contrast agent did not make much difference for measurement of ADC values in benign and malignant tumors. Also, ADC values of solid and cystic components in both benign and malignant tumors before and after administration of contrast were comparable. Conclusion: Our findings support the possibility that DWI optimized may be obtained before or after DCE-MRI without compromising important clinical information.
