Diffuse small-bowel ischemia in hypotensive adults after blunt trauma (shock bowel): CT findings and clinical significance.
The purpose of this study is to describe CT findings of shock bowel (diffuse abnormality of the small bowel observed in hypotensive or hypoperfused patients after blunt abdominal trauma) and to determine the clinical significance of CT-diagnosed shock bowel. ⋯ In trauma patients with hypotension, early abdominal CT may show diffuse abnormalities of the small bowel due to prolonged hypoperfusion--shock bowel--with a normal appearing colon. In this study, the CT findings of shock bowel were reversible and were not associated with clinical symptoms.

The job market for radiology residents and fellows graduating in 1994.
In response to anecdotal reports of grave deterioration in the job market for graduates of radiology training programs, the American College of Radiology undertook a systematic appraisal of this job market for 1994. ⋯ Although the overwhelming majority of 1994 graduates obtained jobs, and these overwhelmingly were jobs of interest, program directors reported that the job market was weakening. Given the changes in the socioeconomic environment--managed care, for example--and the changing job market, training programs should give more attention to the job market in planning for changes in size.

Rotational injury of cervical facets: CT analysis of fracture patterns with implications for management and neurologic outcome.
Imaging studies of patients with rotational facet injuries of the cervical spine were retrospectively reviewed to determine the prevalence and pattern of associated fractures, to correlate injury pattern with recommended surgical stabilization, and to assess neurologic outcome. ⋯ Cervical rotational facet injuries are often accompanied by facet fractures and bilateral damage of the rotated vertebra. These injuries contribute to rotational instability and require specific internal fixation based on a precise delineation of all injuries. Facet dislocations without fractures have a significantly higher association with cord syndromes than do rotational facet injuries with fractures. CT, particularly with parasagittal reformations, is valuable in identifying all injuries of the rotated and subjacent vertebrae.

Comparative Study Clinical Trial Controlled Clinical TrialProspective evaluation of extracranial carotid stenosis: MR angiography with maximum-intensity projections and multiplanar reformation compared with conventional angiography.
The purpose of this prospective study was to compare MR angiography of the carotid artery from the aortic arch through the circle of Willis using maximum-intensity projection (MIP) and multiplanar reformation (MPR) images with intraarterial angiography in the depiction of extracranial carotid atherosclerosis. ⋯ It is possible to image the entire carotid artery from the aortic arch through the circle of Willis with MR angiography in a clinically acceptable time. MPR of the 3D TOF MR angiogram reliably shows the percentage of carotid stenosis with no statistically significant difference compared with intraarterial angiography. The role of MR angiography in showing lesions in the circle of Willis or the aortic arch is promising, but the limited number of tandem lesions in this study makes it difficult to draw any conclusions.
