A 64-year-old female patient with hepatitis-related liver cirrhosis and single segment I HCC lesion. She had a TACE session and came for follow up 1 month 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 elicits high heterogeneous signal in both T1WIs and T2WIs with the periphery of the lesion is seen of restricted diffusion. NO clear areas of enhancement could be seen in the dynamic study; however, the subtraction images shows faint lesion enhancement (false negative dynamic study interpretation). (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. The enhancement became more clear and more appreciated in the dynamic and subtraction images confirming residual/recurrent disease
