Figure 4. Contrast-enhanced magnetic resonance imaging demonstrating: pre-treatment caudate lobe hepatocellular carcinoma with restricted diffusion (ADC 1101 × 10-6) (A); post-stereotactic body radiotherapy scan showing no treatment response with restricted diffusion (ADC 917 × 10-6) (B); and corresponding contrast-enhanced computed tomography and delayed imaging with hepatobiliary contrast agent showing perfusional changes around the tumour with no response (C). ADC: apparent diffusion coefficient
