Dosimetry Based on ^99mTc-Macroaggregated Albumin SPECT/CT Accurately Predicts Tumor Response and Survival in Hepatocellular Carcinoma Patients Treated with ⁹⁰Y-Loaded Glass Microspheres: Preliminary Results

Quantitative (99m)Tc-MAA SPECT/CT is predictive of response, PFS, and OS. Dosimetry based on (99m)Tc-MAA SPECT/CT can be used for the selection of patients and for an adaptation of treatment planning, especially in selected patients (particularly in the case of large tumors). These results also confirm the efficacy and safety of (90)Y-loaded microspheres in treating HCC, even in the presence of PVT (and especially when (99m)Tc-MAA uptake is seen inside the PVT).
