ADC Histogram Analysis Enhances O-RADS MRI for Adnexal Lesion Classification

Adding ADC histogram parameters and CA-125 to O-RADS MRI improved AUC from 0.915 to 0.956 for classifying adnexal lesions in a retrospective study of 235 lesions.

• O-RADS MRI alone had an AUC of 0.915, sensitivity 84.25%, specificity 90.74%, and accuracy 87.23%.
• Combining O-RADS with ADC mean, ADC kurtosis, and CA-125 raised sensitivity to 92.91% (specificity 89.81%, accuracy 90.64%, AUC 0.956).
