Diagnostic CT in arterial (A) and portal (B) phases, showing a 23-mm hypervascular nodule in segment VII with contrast washout, diagnosis of HCC. Tc-99 m MAA SPECT/CT (C) and Y-90-PET/CT (D) image after administration of 0.78 GBq of glass microspheres, showing selective deposition of radioparticles on the tumor and, to a lesser extent, on the rest of the segment. Dosimetric study (E and F) using MIM software, maximum tumor dose 1087 Gy, mean dose 305 Gy
