OF CT SCANS FOR PATIENTS WITH SUSPECTED TBI INDICATE INTRACRANIAL BLEEDING AND/OR SKULL FRACTURE.4
“The number of negative head CT scans represents
high-volume, high-cost, but low-value testing—not to
mention increasingly recognized radiation risk.”4
– Korley et al.
OF mTBI PATIENTS WITH NORMAL HEAD CT SCANS HAD TRAUMA-RELATED ABNORMALITIES ON MAGNETIC RESONANCE IMAGES.5
“[CT-occult injuries] without significant hemorrhage but that nevertheless correlate with a range of clinical deficits… can cause chronic sequelae and impairment, and pose unique challenges to TBI diagnosis and severity stratification.”5
– Yuh et al.
Researchers advise that non-invasive tests based on physical signs—including identifying signs of brain injury on a CT scan—are not sufficiently sensitive to identify increased intracranial pressure (ICP) and should not be used independently to rule out the condition.
”Novel diagnostic tests are needed to improve ED diagnosis and management of TBI, offering the
potential to boost performance metrics without relying on head CT scans.”4
– Korley et al.
2019, JAMA NEUROLOGY: “Most patients with mTBI presenting to US level I trauma centers report persistent, injury-related life difficulties at 1-year postinjury, suggesting the need for more systematic follow-up of patients with mTBI to provide treatments and reduce the risk of chronic problems after mTBI.”1
