Unilateral Muscle Artifacts due to Non-compliance During Uptake Phase of 18F-FDG PET/CT in an Oncologic Patient
Journal Title: Molecular Imaging and Radionuclide Therapy - Year 2018, Vol 27, Issue 1
Abstract
A 49-year-old male patient with a prior history of poor compliance with medical appointments was referred for an 18F-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for the staging of a rectal squamous cell carcinoma. The PET/CT showed unilateral diffuse skeletal muscle 18F-FDG uptake as well as bilateral salivary gland uptake artifacts, suggestive of non-compliance with patient preparation instructions. The PET/CT nurse noted that during the 18F-FDG uptake phase, the patient appeared intoxicated, and she found two beer cans hidden in the waste disposal beside his chair just prior to imaging. The patient only admitted to eating a cookie approximately 30 minutes after the injection of 18F-FDG PET/CT and denied consuming alcohol during the uptake phase. We present the imaging findings of non-compliance with patient instructions during the uptake phase of 18F-FDG.
