Further considerations on hepatic lesion discrimination using diffusion MR imaging.

With great interest, we read the article "Differential diagnosis between hepatic metastases and benign focal lesions using DWI with parallel acquisition technique: a meta-analysis" (by Wei CG et al.). This article suggests that diffusion-weighted imaging was useful for differentiation between hepatic metastases and benign focal lesions. The result is encouraging. We would like to contribute regarding the value of DWI with parallel acquisition technique in the differentiation of metastases and benign hepatic lesions.
