Results

There were 66 patients (mean ages 51.8 ±10.8 yo) with a mean size lesion of 40±25 mm: 37 malignant (56%) and 29 benign (44%) (Figure 2). For DCE-MRI a SE of  94.9% (r1) and 100% (r2) and a SP of 66.7% (r1) and 77.8% (r2) were achieved. For MpMRI the SE was 87.2% (r1) and 90% (r2) and the SP 85.2% for both readers (P>0.5). The reduction of false positive was ranged between 33.3% (6 vs 2)and  55.5% (9 vs 4) (Figure 3). There was substantial agreement for both DCE-MRI and MpMRI readings (k=0.610 vs k=0.719).
