The efficacy of computed tomography (CT) and magnetic resonance imaging (MRI) in identifying traumatic injuries of the brain was compared in a referred population of 21 amateur and professional boxers. Three boxers displayed CT scans with equivocal findings that were verified as artifacts by MRI. Eleven boxers had both CT and MRI scans with normal findings, and 7 boxers had both CT and MRI scans with abnormal findings. There were no instances where abnormalities demonstrated on CT scanning were not detected by MRI. However, some abnormalities detected on MRI were not detected on CT scans. These included a subdural hematoma, white-matter changes, and a focal contusion. Magnetic resonance imaging appears to be the neuroradiodiagnostic test of choice compared with CT.
在21名业余和职业拳击手组成的转诊人群中，比较了计算机断层扫描（CT）和磁共振成像（MRI）在识别脑外伤方面的功效。三名拳击手的CT扫描结果不明确，经MRI证实为伪影。11名拳击手的CT和MRI扫描结果均正常，7名拳击手的CT和MRI扫描结果均异常。没有出现CT扫描显示异常而MRI未检测到的情况。然而，MRI检测到的一些异常在CT扫描中未被检测到。这些异常包括硬膜下血肿、白质改变和局灶性挫伤。与CT相比，磁共振成像似乎是首选的神经放射诊断检查方法。
