Table 4. The optimal diagnostic performance of breast DWI to differentiate malignant from benign lesion or normal breast tissues when acquired at different b values (b =1,000 and b =1,500 s/mm²) and at different B0 (1.5 and 3.0 T).

*, for statistical analysis, benign lesions and normal breast measurements were pooled together and were evaluated against malignant lesions. DWI, diffusion-weighted imaging; ADC, apparent diffusion coefficients.
