Is direct radiologist supervision of abdominal computed tomography (CT) scans necessary?
When abdominal and cranial CT studies were compared, there was no significant difference in the proportion of studies requiring a change in the prescribed protocol following radiologist review of the images obtained. There was no evidence to suggest that abdominal CT was any less suited to protocol.
Findings suggest that athletes who report a distant history of concussion have minimal enduring neurocognitive deficits. Given conflicting findings in the literature, prospective studies that attempt to identify moderating factors are necessary to help determine who is at risk for long-term cognitive difficulties after concussion.
