Contrasts between DWI and DCE curve in diagnosing malignancies of breast non-mass enhancement lesions based on morphology

The diagnosis of NMEs is a challenge for most radiologists based only on morphological information. The value of DWI or DCE curves for discriminating malignant lesions from benign lesions was controversial. We estabished and compared the ADC model (ADC+morphology) and the TIC (TIC+morphology) for detecting malignancy with a relatively large sample size of NME lesions. We found that the TIC model was superior than the ADC model for differentiating between benign and malignant NME lesions. A whole DCE-MRI scan for NMEs is recommended without the need to acquire additional DWI data.
