Utility of 99mTc-MAA SPECT/CT for treatment plan of radioembolization using resin microspheres in HCC patients compared with 90Y PET/CT

The purpose of our study is to validate the utility of 90Y PET/CT compared to SPECT/CT simulation in dosimetry and prediction of treatment response. Subject and method: Thirty-four consecutive hepatocellular carcinoma (HCC) patients, intermediate and advanced stage who underwent 90Y resin microsphere transarterial embolization (TARE) were recruited in the study.
