Hepatocellular Carcinoma Tumor Dose Response After 90Y-radioembolization With Glass Microspheres Using 90Y-SPECT/CT-Based Voxel Dosimetry

Hepatocellular carcinoma tumor dose-response curves after 90Y-radioembolization with glass microspheres showed Dmean of 160 Gy and BEDmean of 214 Gy for D50% with a positive predictive value of ∼70% and a negative predictive value of ∼62%. No complications were observed in our patient cohort for normal liver Dmean less than 44 Gy.
