Although the sensitivity and negative predictive value of DW imaging for the detection of perilesional viable tumor after local treatment of HCCs in cirrhotic patients were better than those of conventional contrast-enhanced MR imaging, the accuracy of diffusion weighted imaging alone is not good as conventional contrast-enhanced MR images. DW imaging can be used to improve the detection of perilesional viable tumor, in association with conventional MR images.
