Representative image from a 62-year-old female in progressive group before radiofrequency ablation (RFA) treatment for hepatocellular carcinoma (HCC). (A) Apparent diffusion coefficient (ADC) histogram image. The area covered by green shadow is the ADCmedian area; (B) ADC image shows the maximum section area. The whole lesion is the regions of interest (ROI), and the green shadow inside is the ADCmedian area. The ROI area of the lesion at the posterior right lobe of liver is 2,211 mm2, lesion ADCmax=1.77×10–3 mm2/s, ADCmedian=1.56×10–3 mm2/s and RADCmedian=0.74.
