Figure 3. Loculated pericardial effusion in a 65-year-old man with recent thoracotomy. Axial contrast-enhanced CT scan shows a loculated pericardial effusion that compresses the right atrium. The parietal pericardium (arrow) clearly separates the loculated pericardial effusion (*) from the pleural effusion (P).

Figure 10a. Constrictive pericarditis in a 65-year-old man who had had symptoms of right heart failure for 3 months. (a) Axial ECG-gated T1-weighted SE image shows pericardial thickening (arrows), which is most visible near the right ventricle. The right ventricle has a narrow tubular shape secondary to pericardial constriction. (b) Axial T1-weighted SE image obtained at a level slightly caudad to that in a shows dilatation of the inferior vena cava (IVC) and ascites (*).

(a) Axial ECG-gated T1-weighted SE image shows a crescent-shaped area of intermediate signal intensity (arrows) surrounding the ventricles, which indicates either pericardial thickening or pericardial effusion. (b) Axial gadolinium-enhanced fat-saturated T1-weighted SE image shows marked thickening and enhancement in the pericardium (arrows), findings consistent with inflammation. A moderate-sized pericardial effusion is also depicted.

Figure 20a. Chronic organized pericardial hematoma in a 39-year-old man who presented with syncope and chest discomfort and had a history of blunt chest trauma 8 years prior. (a) Axial ECG-gated T1-weighted SE image shows a well-circumscribed mass (M) with intermediate signal intensity in the left atrioventricular groove; the mass compresses the left atrium and ventricle. (b) Axial cine GRE image shows a mass (M) with low-signal-intensity foci and a low-signal-intensity rim (arrows), which are indicative of central and peripheral calcifications. These findings were confirmed at subsequent surgery.
