Physiologic variant FDG uptake in scalene muscle has be recognized as a potential pitfall in head and neck PET or PET/CT. The patterns of uptake are usually bilateral, symmetrical and linear; and the intensity is low. We herein presented a lung cancer patient with painful chest wall invasion undergoing FDG-PET/CT for follow-up. There was unilateral, focal(More)
OBJECTIVE Gastrointestinal bleeding scintigraphy (GIBS) offers the advantage of continuous monitoring of patients to localize the site of gastrointestinal bleeding. In this study, a modified in vivo labeling method with sedimentation of the labeled red blood cells (RBC) was applied to remove free technetium-99m (99mTc) and increase labeling efficiency. (More)
Parkinson's disease (PD) is a neurodegenerative disease characterized by progressive loss of dopaminergic neurons in the basal ganglia. Single photon emission computed tomography (SPECT) scans using [99mTc]TRODAT-1 can image dopamine transporters and provide valuable diagnostic information of PD. In this study, we optimized the scanning parameters for(More)
An ectopically located gallbladder is rare and unusual. In this study, we described a case of a 52-year-old woman who underwent SPECT-myocardial perfusion imaging because of exertional dyspnea and chest tightness. The rest sinograms reveal 2 substantially increased tracer uptakes in the right chest. Subsequently, a SPECT/CT scan was performed to clarify the(More)
Fluorine-18-fluorodeoxyglocose (18 F-FDG) positron emission tomography (PET) or PET/computed tomogra-phy (CT) is a powerful modality in the staging, follow-up and therapeutic evaluation of oncologic patients, including lung cancer. However, FDG is not a specific tracer for cancer and false-positive uptake occasionally occurred. Here, we present a(More)
