Figure 10b. 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 (*).
