Abstract Background It is uncertain whether myocardial fluorodeoxyglucose uptake occurs solely due to physiological features or if it represents a metabolic disarrangement under chemotherapy. Objective To investigate the chemotherapy effects on the heart of patients with lymphoma by positron emission tomography associated with computed tomography scans (PET/CT) with 2-deoxy-2[18F] fluoro-D-glucose (18F-FDG PET/CT) before, during and/or after chemotherapy. Methods Seventy patients with lymphoma submitted to18F-FDG PET/CT were retrospectively analyzed. The level of significance was 5%.18F-FDG cardiac uptake was assessed by three […]
