Meta Analysis
Traumatic aortic injury: diagnosis with contrast-enhanced thoracic CT--five-year experience at a major trauma center.
To review the literature and the authors' experience with admission contrast material-enhanced computed tomography (CT) in patients admitted after blunt trauma. ⋯ The CT finding of mediastinal hemorrhage alone is sensitive for traumatic aortic injury, but the finding of aortic injury is more specific.

Comparative Study
Liver masses: replacement of conventional T2-weighted spin-echo MR imaging with breath-hold MR imaging.
To evaluate breath-hold magnetic resonance (MR) imaging with single-shot and multishot T2-weighted fast spin-echo (SE) and inversion-recovery (IR) SE echo-planar (EP) SE (IR-SE-EP) sequences compared with conventional T2-weighted SE imaging for detection of liver masses. ⋯ T2-weighted breath-hold imaging, particularly IR-fast-SE imaging, was more sensitive for hepatic masses than conventional SE imaging, with a substantial reduction in acquisition time. Half-Fourier-single-shot-fast-SE imaging was especially useful in patients who were unable to hold their breath.
