CT and MR evaluation of pericardial and retrosternal adhesions after cardiac surgery.
The visibility of the pericardium as well as of the space between the dorsal aspect of the sternal surface and the pericardial surface after cardiac surgery was determined by CT and/or MR with electrocardiographic (ECG)-gated spin-echo (SE) and gradient-echo sequences. Seventeen patients who had undergone cardiac operations and who were admitted for cardiac reoperation were investigated with CT and/or MR prior to sternal reentry. Five patients were investigated with CT alone, ten with both CT and MR, and two with MR only. ⋯ Computed tomography could not detect intrapericardial adhesions. Magnetic resonance was sensitive to metal artifacts from sternal sutures in both sequences and could therefore not be used to detect postoperative retrosternal extrapericardial adhesions. On the other hand, MR with ECG-gated SE sequences confirmed intrapericardial adhesions in 44 of 57 locations.

Case ReportsPreduodenal portal vein and anomalous continuation of inferior vena cava: CT findings.
Four cases of a rare congenital anomaly, preduodenal portal vein (PPV), are presented. Preduodenal portal vein is known to be frequently associated with other anomalies including intestinal malrotation, situs inversus, biliary atresia, and pancreatic, splenic, and cardiac anomalies. Of our four cases, three had azygos or hemiazygos continuation of the inferior vena cava and other anomalies. We want to call attention to association of azygos or hemiazygos continuation of inferior vena cava with PPV.
