This proposal will test the diagnostic utility of fast magnetic resonance (MR) in young children with Traumatic brain Injury (TBI).
In children, TBI causes >2000 deaths, 35,000 hospitalizations and 470,000 emergency department visits in the US each year, making it a leading cause of pediatric disability and death. Currently 20-50% of these children undergo computed tomography (CT) scanning, exposing them to harmful radiation, and increasing their lifetime risk of cancer. Risks are especially increased in children because the neurologic exam is less reliable, because growing tissues are more vulnerable to radiation, and because children have more years to accumulate harmful mutations.
Fast MR is a short, motion-tolerant protocol that has been used in children with shunted hydrocephalus to eliminate radiation exposure without the need for sedation. However, fast MR has not been validated in children with TBI, a critical gap. The investigators will measure feasibility and diagnostic utility of fast MR in children < 6 years (72 months) old who undergo head CT for TBI.
The Investigator will recruit children in whom a head CT is ordered for TBI. Consenting subjects will undergo fast MR shortly after CT and results will be compared to determine: 1) whether fast MR identifies all traumatic injuries identified by CT and 2) whether fast MR without sedation can be performed quickly and successfully.
|Condition or disease||Intervention/treatment||Phase|
|TBI (Traumatic Brain Injury)||Procedure: Fast MR Procedure: Computed Tomography||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||400 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Fast MR for Young Children With Traumatic Brain Injury|
|Study Start Date :||April 2015|
|Estimated Primary Completion Date :||October 2018|
|Estimated Study Completion Date :||November 2018|
Experimental: Fast magnetic resonance imaging (Fast MR)
All subjects will undergo fast MR in addition to Computerized Tomography (CT) (the current criterion standard). Fast MR will be interpreted independently for research purposes by 2 blinded radiologists. Consensus interpretation will be compared to the clinical reading of the CT.
Procedure: Fast MR
Enrolled subjects will undergo fast MR within 24 hours of CT completion. Subjects will be scanned using one of 2 Philips Ingenia MR 3T scanners. The estimated duration of the fast MR is less than 5 minutes, even if up to 2 sequences are repeated for motion.
Other Name: Magnetic Resonance Imaging
Procedure: Computed Tomography
The Investigator will recruit children in whom a head CT is ordered as standard of care for TBI. Consenting subjects will undergo fast MR shortly after CT and results will be compared.
- Diagnostic utility (sensitivity/specificity) of fast MR to identify radiographic evidence of trauma as determined by dual, independent review by 2 masked pediatric neuroradiologists [ Time Frame: 0-15 minutes ]The main outcome measure will be the identification of radiographically apparent brain injury using cranial CT as the gold standard. Diagnostic utility (sensitivity/specificity) of fast MR to identify radiographic evidence of trauma (yes/no) as determined by dual, independent review by 2 masked pediatric neuroradiologists and compared to the clinical interpretation of CT (the current criterion standard).
- Accuracy of fast MR to determine type and location of injury as determined by dual, independent review by 2 masked pediatric neuroradiologists and compared to the clinical interpretation of CT (the current criterion standard). [ Time Frame: 0-15 minutes ]
- Completion rate: determined by the number of fast MR's completed per protocol parameters (all sequences completed in <30 minutes; no request to stop imaging from physician, patient or family) [ Time Frame: 0-5 minutes ]
- Imaging time as determined by the time to complete all images - timer embedded in MR device [ Time Frame: 0-5 minutes ]
