The value of Multiplex MRI in differential diagnosis of benign and malignant ovarian lesions with O-RADS MRI Score 3-5

Motivation: The differentiation of benign and malignant ovarian lesions is challenging and crucial. Thus new technologies is in need. Goal(s): To investigate the diagnostic efficacy of Multiplex MRI (MTP) in differentiation of benign and malignant ovarian lesions with O-RADS MRI score 3-5. Approach: The quantitative MTP parameters before and after enhancement were compared between benign and malignant groups, and ROC curve was used to evaluate the diagnostic efficacy of the quantitative parameters and diagnostic models. Results: The MTP MRI emerges as a valuable tool in differentiation of benign and malignant ovarian lesions with O-RADS Score 3-5 and could provide additional diagnostic value than ADC. Impact: MTP MRI can provide multiple quantitative parameters from a single scan. Our study found that MTP MRI yielded good performance in differentiation of benign and malignant ovarian lesions. The utility of MTP in diagnosis of ovarian lesion worth more investigation.
