Head CT in Emergency Care may be Overused

Head CT scans are too often given to patients in emergency care to check for skull fractures and brain hemorrhage. This leads to unnecessary medical costs and unwanted exposure to radiation, according to a study to be presented at the ARRS 2018 Annual Meeting, set for April 22-27 in Washington, DC.

The study, to be presented by Michaela Cellina, of the Radiology Department of Fatebenefratelli-Sacco Hospital in Milan, Italy, evaluated head CT scans executed for minor head injury (MHI) in patients aged 18-45 who presented to the hospital's emergency department between January 1 and June 30, 2016. For each CT scan, scientists determined whether the CT referral met the criteria indicated by the National Institute for Health and Care Excellence (NICE) and the Canadian CT Head Rule (CCHR).

Computed Tomography

Computed Tomography (CT) scan is a type of medical examination that uses X-rays and computer processing to create sectional images of the body to provide more efficient results than X-rays.

‘Only 15 out of 260 scans have showed positive results for skull fracture and other related head injuries.’

Of 492 cases reviewed, 260 (52.8%) and 376 (76.4%) of the CT examinations were not indicated according to the NICE and CCHR, respectively. Scientists noted no statistically significant difference between the specialty and seniority of the referring physician and over-referral, or between the patient's age and unwarranted CT studies. Motor vehicle accidents, however, were associated with a higher rate of non-indicated CT examinations for both NICE and CCHR, and two-wheel vehicle driver accidents were associated with a higher rate of appropriated CT exams for both NICE and CCHR. Only 15 of the 260 CT examinations were positive for brain hemorrhage, subarachnoid hemorrhage, or skull fracture.

With educational activities representing the entire spectrum of radiology, ARRS will host leading radiologists from around the world at the ARRS 2018 Annual Meeting, April 22-27, at the Marriott Wardman Park Hotel in Washington, DC.

Skull Fractures

Skull Fracture is an injury that causes a break in the outer layer of skull bones. Symptoms of skull fractures include symptoms caused due to fracture itself, and injury to vessels, nerves and brain.

Head Fracture to be Predicted With a Biomarker in Blood

Measuring markers of bone injury in the blood can help predict the likelihood of a cranial lesion and determine the need for head computed tomography, in cases of traumatic brain injury.
