Periportal low density on CT in patients with blunt trauma: association with elevated venous pressure.
We postulated that the CT finding of periportal low density after acute blunt trauma of the abdomen or pelvis results from elevated central venous pressure caused by rapid expansion of intravascular volume during IV resuscitation or by other trauma-related pathologic changes. ⋯ The CT finding of periportal low density after blunt abdominal trauma indicates acute elevation of central venous pressure and does not by itself signify hepatic parenchymal injury, as has been previously reported.

Partial anomalous pulmonary venous drainage of the left upper lobe vs duplication of the superior vena cava: distinction based on CT findings.
Partial anomalous pulmonary venous drainage of the left upper lobe and duplication of the superior vena cava have similar appearances on CT scans. The purpose of this study was to review their appearances and provide guidelines for differentiating between them. ⋯ Careful analysis of the CT scans with particular attention to these two features allows differentiation between partial anomalous pulmonary venous drainage of the left upper lobe and duplication of the superior vena cava.
