Same patient as Fig. 1. a Contrast-enhanced computed tomography (CECT) image: HCC located between segments IV and VIII. b ^99mTc-MAA SPECT/CT fusion image shows low uptake in the lateral part of the tumoral nodule. ^99mTc-MAA activity was split in two doses of 50% each by IR decision, based on liver and tumoral volumes. c, c1 and c2 C-arm cone-Beam CT (CBCT) volumetric assessment of the tumoral territory perfused by each artery. VIII segments artery (in green) fed only 32% of the tumoral volume while IV segment artery fed most of it (in orange). d ⁹⁰Y PET/CT fusion image after splitting the activity according to CBCT volumes shows the adequate distribution of the microspheres throughout the lesion
