CTA improves as first-line test for traumatic neck injury
By Eric Barnes
There are clinical guidelines for determining which trauma patients should undergo CT of the neck, but there is little definitive advice on which patients should undergo CT angiography (CTA) to screen for blunt cerebrovascular injury (BCVI). Dr. Michael Lev, director of emergency neuroradiology at Boston's Massachusetts General Hospital, discusses the use of extracranial vascular imaging, particularly CTA, in blunt trauma patients admitted to the emergency department.

Dual-source coronary CTA largely unaffected by heart rate
By Eric Barnes
As multidetector CT scanners have added detector rows over the years, faster and faster heart rates have been required to cause motion artifacts significant enough to reduce the diagnostic accuracy of coronary CT angiography (CTA). Researchers in Europe recently studied how dual-source CT performs with high heart rates, and found that diagnostic image quality is sufficient for a wide range of heart rates and heart rate variability.
