Split-Dose 18F-FDG PET/CT-Guided Microwave Ablation for Liver Metastasis Recurrence with Immediate Treatment Assessment

J Nucl Med Technol. 2019 Mar;47(1):88-89. doi: 10.2967/jnmt.118.217406. Epub 2019 Jan 25.

Abstract

A 48-y-old man with a history of colon cancer presented with recurrent hepatic metastasis along a prior microwave ablation bed. Split-bolus, intraprocedural 18F-FDG PET was performed to guide repeat microwave ablation and immediately confirm complete treatment. PET-guided ablation is highly accurate for targeting and treating malignant hepatic lesions and feasible for nonspecialized tertiary care hospitals without an onsite cyclotron.

Keywords: 18F-FDG PET/CT; PET/CT-guided ablation; liver metastasis.
