Abstract:
An F-FDG-PET with CT scan was performed to stage a tongue cancer, revealing the hypermetabolic region in the thoracic vertebra. This corresponded to a benign lesion seen on MRIs and CT.Although these findings suggested a vertebral hemangioma, "hot" vertebra in FDG-PET was atypical. The final diagnosis was confirmed capillary hemangioma by the scopic biopsy and this lesion was no change at 1 year later.Careful interpretation of metabolic (FDG-PET) and anatomic (CT and MRI) images should be performed to accurately characterize the foci of increased FDG uptake.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
