Is whole-body CT necessary after motor vehicle crashes?
Using whole-body CT to evaluate patients with normal physical presentation following a motor vehicle crash did not prompt any changes in their medical care in a new study, published online May 28 in Radiology. The findings question the value of the imaging technique in some emergency trauma cases.

Head CT offers low diagnostic yield for fainting
More than half of all patients who faint still undergo head CT despite a diagnostic yield of less than 3% for the exam, according to an article published in the May issue of Academic Emergency Medicine. Researchers from Canada say it's high time to cut back on using the test for most patients.
