Magnetic resonance imaging (MRI) is used rarely in the acute evaluation of traumatic brain injury (TBI) but may identify findings of clinical importance not detected by computed tomography (CT). We aimed to characterize the association of cytotoxic edema and hemorrhage, including traumatic microbleeds, on MRI obtained within hours of acute head trauma and investigated the relationship to clinical outcomes. Patients prospectively enrolled in the Traumatic Head Injury Neuroimaging Classification study (NCT01132937) with evidence of diffusion-related findings or hemorrhage on neuroimaging were included. Blinded interpretation of MRI for diffusion-weighted lesions and hemorrhage was conducted, with subsequent quantification of apparent diffusion coefficient (ADC) values. Of 161 who met criteria, 82 patients had conspicuous hyperintense lesions on diffusion-weighted imaging (DWI) with corresponding regions of hypointense ADC in proximity to hemorrhage. Median time from injury to MRI was 21 (10–30) h. Median ADC values per patient grouped by time from injury to MRI were lowest within 24 h after injury. The ADC values associated with hemorrhagic lesions are lowest early after injury, with an increase in diffusion during the subacute period, suggesting transformation from cytotoxic to vasogenic edema during the subacute post-injury period. Of 118 patients with outcome data, 60 had Glasgow Outcome Scale Extended scores ≤6 at 30/90 days post-injury. Cytotoxic edema on MRI (odds ratio [OR] 2.91 [1.32–6.37], p = 0.008) and TBI severity (OR 2.51 [1.32–4.74], p = 0.005) were independent predictors of outcome. These findings suggest that in patients with TBI who had findings of hemorrhage on CT, patients with DWI/ADC lesions on MRI are more likely to do worse.

与出血相关的细胞毒性水肿预示着创伤性脑损伤后的不良结果

磁共振成像 (MRI) 很少用于创伤性脑损伤 (TBI) 的急性评估,但可以识别计算机断层扫描 (CT) 未检测到的具有临床重要性的发现。我们的目的是在急性头部外伤数小时内获得的 MRI 上表征细胞毒性水肿和出血(包括外伤性微出血)的关联,并研究其与临床结果的关系。纳入了前瞻性纳入创伤性头部损伤神经影像学分类研究 (NCT01132937) 的患者,这些患者具有弥散相关发现或神经影像学出血的证据。对弥散加权病变和出血的 MRI 进行了盲法解释,随后对表观弥散系数 (ADC) 值进行了量化。在符合条件的 161 人中,82 名患者在弥散加权成像 (DWI) 上有明显的高信号病变,在出血附近有相应的低信号 ADC 区域。从受伤到 MRI 的中位时间为 21 (10–30) 小时。按从受伤到 MRI 的时间分组的每位患者的中位 ADC 值在受伤后 24 小时内最低。与出血性病变相关的 ADC 值在损伤后早期最低,在亚急性期扩散增加,表明在损伤后亚急性期从细胞毒性水肿转变为血管源性水肿。在 118 名有结果数据的患者中,60 名在受伤后 30/90 天的格拉斯哥结果量表扩展评分≤6。MRI 上的细胞毒性水肿(比值比 [OR] 2.91 [1.32–6.37],从受伤到 MRI 的中位时间为 21 (10–30) 小时。按从受伤到 MRI 的时间分组的每位患者的中位 ADC 值在受伤后 24 小时内最低。与出血性病变相关的 ADC 值在损伤后早期最低,在亚急性期扩散增加,表明在损伤后亚急性期从细胞毒性水肿转变为血管源性水肿。在 118 名有结果数据的患者中,60 名在受伤后 30/90 天的格拉斯哥结果量表扩展评分≤6。MRI 上的细胞毒性水肿(比值比 [OR] 2.91 [1.32–6.37],从受伤到 MRI 的中位时间为 21 (10–30) 小时。按从受伤到 MRI 的时间分组的每位患者的中位 ADC 值在受伤后 24 小时内最低。与出血性病变相关的 ADC 值在损伤后早期最低,在亚急性期扩散增加,表明在损伤后亚急性期从细胞毒性水肿转变为血管源性水肿。在 118 名有结果数据的患者中,60 名在受伤后 30/90 天的格拉斯哥结果量表扩展评分≤6。MRI 上的细胞毒性水肿(比值比 [OR] 2.91 [1.32–6.37],表明在亚急性损伤后期间从细胞毒性水肿转变为血管源性水肿。在 118 名有结果数据的患者中,60 名在受伤后 30/90 天的格拉斯哥结果量表扩展评分≤6。MRI 上的细胞毒性水肿(比值比 [OR] 2.91 [1.32–6.37],表明在亚急性损伤后期间从细胞毒性水肿转变为血管源性水肿。在 118 名有结果数据的患者中,60 名在受伤后 30/90 天的格拉斯哥结果量表扩展评分≤6。MRI 上的细胞毒性水肿(比值比 [OR] 2.91 [1.32–6.37],p  = 0.008) 和 TBI 严重程度 (OR 2.51 [1.32–4.74], p  = 0.005) 是结果的独立预测因子。这些发现表明,在 CT 上有出血发现的 TBI 患者中,MRI 上有 DWI/ADC 病变的患者更有可能表现更差。
