a Contrast-enhanced computed tomography (CECT) image in a patient with HCC located between segments IV and VIII. b Volumetric assessment of the target volume in SPECT/CT fusion images after the injection of 99mTc-MAA through IV and VIII segments arteries. The volume was obtained using a “volume of interest and isocontour” tool, drawn in purple. c C-arm cone-beam CT (CBCT) showing contrast uptake in the tumoral lesion with no perfusion in non-tumoral parenchyma. d Volumetric assessment of the final target volume in the 90Y PET/CT fusion images
