The cost-effectiveness of oblique radiography in the exclusion of C7-T1 injury in trauma patients.
The purpose of our study was to compare the cost-effectiveness of bilateral oblique radiography with that of CT for excluding C7-T1 injury in trauma patients. ⋯ Because bilateral oblique radiography appears to be cost-effective for the exclusion of cervical spine injuries, we suggest that it be performed routinely.

The situation of diagnostic radiology training programs and their graduates in 1997.
In light of concerns about the job market, the American College of Radiology studied the employment situation of 1997 graduates from diagnostic radiology training programs and the status and plans of these programs. ⋯ Unemployment continues to be low. The 1997 job market has improved over the 1996 job market, but job prospects in nuclear medicine continue to be more problematic than in other subspecialties.

Correlation of dynamic contrast-enhanced MR imaging with histologic tumor grade: comparison of macromolecular and small-molecular contrast media.
The endothelial integrity of microvessels is disrupted in malignant tumors. Quantitative assays of tumor microvascular characteristics based on dynamic MR imaging were correlated with histopathologic grade in mammary soft-tissue tumors. ⋯ Quantitative tumor microvascular permeability assays generated with macromolecular MR imaging contrast medium correlate closely with histologic tumor grade. No significant correlation is found using small-molecular gadopentetate.
