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

Figure 2 Localization and characterization of abnormal fluorodeoxygluocse activity in the heart. A: Axial PET-CT images in patient with history of invasive thymoma underwent surgical resection shows intense FDG focal uptake in the cardiac apex highly suspicious for cardiac metastases, review CT component of PET-CT shows area of and soft tissue; B: Four-chamber DE image with triple inversion recovery shows complete fat suppression of the apical activity in keeping with brown fat (arrow), with high signal fluid intensity consistent with post-operative lobulated fluid collection (arrowhead). PET: Positron emission tomography; CT: Computed tomography; FDG: Fluorodeoxygluocse.
