Diving accidents related to barotrauma constitute a unique subset of ischemic insults to the CNS. Victims may demonstrate components of arterial gas embolism, which has a propensity for cerebral involvement, and/or decompression sickness, with primarily spinal cord involvement. Fourteen patients with diving-related barotrauma were studied with MR imaging of the brain and spinal cord and with CT of the brain. In four patients with presumed cerebral gas embolism, cranial MR was abnormal in three patients while CT was abnormal in only one. Twelve patients had decompression sickness and spinal cord symptoms. MR documented spinal cord abnormalities in three patients. However, scans obtained early in our study were frequently limited by technical constraints. MR of the brain is more sensitive than conventional CT scanning techniques in detecting and characterizing foci of cerebral ischemia caused by embolic barotrauma to the CNS. Although spinal MR may be less successful in the localization of spinal cord lesions related to decompression sickness, these lesions were previously undetectable by other neuroimaging methods.
与气压伤相关的潜水事故构成了中枢神经系统缺血性损伤的一个独特子集。受害者可能表现出动脉气体栓塞的症状，这种栓塞易累及脑部，和/或减压病，主要累及脊髓。对14例与潜水相关的气压伤患者进行了脑部和脊髓的磁共振成像（MR）以及脑部计算机断层扫描（CT）检查。在4例疑似脑气体栓塞的患者中，3例患者的头颅MR异常，而只有1例患者的CT异常。12例患者患有减压病并伴有脊髓症状。MR记录了3例患者的脊髓异常。然而，在我们研究早期获得的扫描结果常常受到技术限制。在检测和表征由中枢神经系统栓塞性气压伤引起的脑缺血病灶方面，脑部MR比传统CT扫描技术更敏感。尽管脊髓MR在定位与减压病相关的脊髓病变方面可能不太成功，但这些病变以前用其他神经影像学方法无法检测到。
