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

Figure 5 Differnation between tumoral thrombus from bland thrombus. A: Differnation between tumoral thrombus from bland thrombus in patient with history of thyroid cancer treated with total thyroidectomy presented with neck mass. Coronal fused FDG-PET image shows intense linear FDG uptake from in the thyroid bed (white arrow) and spreading through SCV to the right atrium (red arrow); B: Four chamber cine image shows irregularly defined mass in the right atrium (arrow), the rest of cardiac examination was unremarkable; C: Axial HASTE at the junction of superior vena cava and right atrium shows a high signal intensity mass (arrow). PET: Positron emission tomography; CT: Computed tomography; FDG: Fluorodeoxygluocse.
