Results

qualitative/quantitative analysis.

19 (79%) malignant lesions (fig. 1b) and 4 (28%) benign lesions were ipointense in hepatobiliary phase ;
5 (21%) malignant lesions and 10 (71%) benign lesions (fig. 2b) were iso/hyperintense in hepatobiliary phase.
17 (71%) malignant lesions (fig. 1a) and 3 (21%) benign lesions shown high signal in DWI (with high b-factor).
7 (29%) malignant lesions and 11 (78%) benign lesions (fig 2a) were iso/hypointense in DWI.
