Diffusion-weighted imaging with two different β-Values in detection of solid focal liver lesions

Abstract

One hundred and eighty-Two consecutive patients with suspected liver disease were recruited to receive diffusion-weighted imaging (DWI) with two different β-values, in comparison with T2-weighted imaging (T2WI). The detection rate of three MR sequences in solid focal liver lesions (FLLs) and subgroup analyses were performed. Our prospective study found that DWI600 was equivalent to DWI100 and T2WI for the detection of solid FLLs overall but was significantlymore accurate in the detection ofmalignant solid FLLs and lesions larger than 10 mm.
