Reply to comments on a??State of the art in magnetic resonance imaging of hepatocellular carcinomaa??: the role of DWI

摘要

We were very pleased to read the comments from Dr Granata and colleagues in Radiology and Oncology about our article “State of the art in magnetic resonance imaging of hepatocellular carcinoma”.1 As highlighted, the diffusion weighted imaging (DWI) plays a key role as a qualitative and quantitative method in the detection of hepatocellular carcinoma (HCC), mostly for small ( 20 mm) or well-differentiated HCC with atypical post-contrast imaging patterns2, helping differentiate benign from malignant focal hepatic lesions, and also allowing the evaluation of treatment response to systemic and locoregional therapies in hepatic malignancies.
