Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) has revealed many unusual presentations and early detection of metastasis in many carcinomas. Epidural involvement in the spine is mostly sequelae of direct infiltration from bony involvement. Direct hematogenous spread to epidural space is very rare. Early(More)
CONTEXT F-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT) scan and hypothyroidism. AIMS The aim was to determine whether the intensity of diffuse thyroid gland uptake on F-18 FDG PET/CT scans predicts the severity of hypothyroidism. MATERIALS AND METHODS A retrospective analysis of 3868 patients who underwent(More)
BACKGROUND Functional status/contractile behaviour of hibernating myocardium was analyzed objectively by analyzing the available quantitative parameters obtained on gated SPECT myocardial perfusion imaging (MPI) using Emory cardiac toolbox (ECTB) software. MATERIALS AND METHODS In this retrospective study, 70 patients with perfusion defects on(More)
