CT Scan

New York, April 3: The idea of a blood test detecting intensity of head injury and function of the blood-brain barrier (BBB) may soon become a reality as a study by University of Rochester Medical Center researchers shows promising results.

According to the research, whose findings appear in the April edition of 'Journal of Emergency Nursing', the screening called S-100B blood test can be a safe alternative to a computed tomographydefine (CTdefine) scan.

A: A "CTdefine" scan or "CAT" scan are terms used to describe a diagnostic technology known as computerized tomographydefine, or computed axial tomography. The CT scanner uses X-rays to take pictures of cross-sections of the body, which are then digitally assembled to give physicians detailed, cross-sectional views of internal organs and tissues.
