CU researchers: Fast MRIs offer alternative to CT scans for pediatric head injuries

AURORA, Colo. (Sept. 18, 2019) – Scientists from the University of Colorado School of Medication have actually launched a research study that reveals that a brand-new imaging approach “fast MRI” works in recognizing terrible brain injuries in kids, and can prevent direct exposure to ionizing radiation and anesthesia.

The outcomes of the research study, which are released in the journal Pediatrics, develop a brand-new, low-risk method to test for brain injuries. The research study was developed to identify the expediency and precision of “fast MRI,” or magnetic resonance imaging, when compared to calculated tomography (CT) scanning.

“We found that fast MRI is a reasonable alternative to CT,” stated Daniel Lindberg, MD, associate teacher of emergency situation medication at the CU School of Medication and lead author of the post. “Nearly all – 99 percent – of fast MRIs were completed successfully, with accuracy that was similar to CT, while avoiding the harms of radiation exposure.”

Each year as lots of as 1.6 million kids go to U.S. emergency situation departments with an issue for terrible brain injury. As lots of as 70 percent go through CT scanning, which exposes the kids to ionizing radiation and increased threat of cancer.

Standard MRI can determine injuries without radiation direct exposure, however needs the kid to stay still for numerous minutes. Standard MRI needs anesthesia, which is not useful in lots of hurt kids and might expose them to moderate cognitive injury. Fast MRI prevents the requirement for sedation by utilizing much faster, and more motion-tolerant imaging strategies.

In Between June 2015 and June 2018, the CU scientists hired individuals to their research study. Kid less than 6 years of ages who had actually currently gone through CT scans throughout their emergency situation care were qualified to take part and those registered got fast MRI as quickly as possible, normally within 24 hours of the CT scan.

Of the 225 kids registered, fast MRI was finished in 223. The average imaging time in fast MRI was 6 minutes, 5 seconds. Fast MRI results matched those of CT in higher than 90 percent of cases. CT revealed much better precision for recognizing fractures or breaks to the skull, while fast MRI did a much better task of imaging the brain and the space in between the brain and skull.

One constraint of the research study is that it might not use to other settings without gain access to to advanced MRI scanners or knowledgeable pediatric radiologists. “We were fortunate to be using newer scanning equipment and highly experienced technicians and pediatric radiologists,” Lindberg stated. “While we believe our findings reveal a feasible alternative to CTs in pediatric specialty centers, further study is necessary to test the results in other settings.”


In addition to Lindberg, 9 other CU School of Medication professor are co-authors of the research study: Nicholas V. Stence, MD, Joseph A. Grubenhoff, MD, MSCS, Terri Lewis, PhD, David M. Mirsky, MD, Angie L. Miller, MD, Brent R. O’Neill, MD, Kathleen Grice, Peter Mourani, MD, and Desmond K. Runyan, MD, DrPH.
