PURPOSE: Approximately 90% of concussions are transient, with symptoms resolving within 10-14  days. However, a minority of @entity1 remain symptomatic several months @entity130 , a condition known as @entity6413 ( @entity6413 ). The treatment of these @entity1 can be challenging. The goal of our study was to assess the utility and cost-effectiveness of neurologic imaging two or more weeks @entity130 in a cohort of youth with @entity6413 . METHODS: We conducted a retrospective study of 52 pediatric @entity1 with persistent post-concussion symptoms after 3  months. We collected demographics and neuroimaging results obtained greater than 2  weeks post-concussion. Neuroimaging ordered in the first 2  weeks post-concussion was excluded, except to determine the rate of re-imaging. Descriptive statistics and corresponding cost data were collected. RESULTS: Of 52 @entity1 with @entity6413 , 23/52 (44  %) had neuroimaging at least 2  weeks after the initial injury, for a total of 32 diagnostic studies. In summary, 1/19 MRIs (5.3  %), 1/8 CTs (13  %), and 0/5 x-rays (0  %) yielded significant positive findings, none of which altered clinical management. Chronic phase neuroimaging estimated costs from these 52 pediatric @entity1 totaled  129,025. We estimate the cost to identify a single positive finding was  21,000 for head CT and  104,500 for brain MRI. CONCLUSIONS: In this cohort of pediatric @entity6413 @entity1 , brain imaging in the chronic phase (defined as more than 2  weeks after concussion) was pursued in almost half the study sample, had low diagnostic yield, and had poor cost-effectiveness. Based on these results, outpatient management of pediatric @entity1 with long-term post-concussive symptoms should rarely include repeat neuroimaging beyond the acute phase.
