Cardiac and pericardial tumors: A potential application of positron emission tomography-magnetic resonance imaging

Figure 3 Localization and characterization of abnormal fluorodeoxygluocse activity adjacent to the heart. A: Localization and characterization of abnormal FDG activity adjacent to the heart. Axial PET-CT image of the heart shows a non-FDG avid nodule near the base of the heart (arrow), PET-CT was performed for incidentally discovered nodule mass on Echocardiography. The study was otherwise unremarkable; B: Axial first pass perfusion image shows highly vascular intrapericardial tumors with no evidence of tissue invasion (arrow); this lesion was surgically removed and pathologically proven schwannoma. PET: Positron emission tomography; CT: Computed tomography; FDG: Fluorodeoxygluocse.
