A 55-year-old male patient with hepatitis-related liver cirrhosis and single segment VIII HCC lesion. He had a TACE session and came for follow up 1 and 3 months later. (A) Follow up dynamic MRI 1 month post TACE. a T2WI, b DWI image, c ADC image, d T1WI, e late arterial phase, f portal phase, g delayed phase, and h late arterial subtracted image. The treatment zone exhibits high signal in T1WIs and mildly increased signal in T2WIs with peripheral marginal enhancement. Subtraction removed the central high signal thus excluding residual disease. (B) Follow up dynamic MRI 3 months post TACE. a T2WI, b DWI image, c ADC image, d T1WI, e late arterial phase, f Portal phase, g delayed phase, and h late arterial subtracted image. Note that the lesion became of low to intermediate signal in T2WIs and iso to high signal intensity in T1WIs. The marginal enhancement became inconspicuous. High signal that was detected on the DWI is decreased in the follow up. No enhancement detected at the subtraction images confirming the complete response
