摘要目的动脉再通术(IAR)后,出血和血脑屏障(BBB)的破坏可用双能量CT(DECT)进行区分。本研究评估DECT是否可用于预测未来梗死的进展。方法对20例IAR后的病人经DECT扫描发现的45处BBB破坏区进行分析,并与随访结果进行对比。利用碘图(IM)和虚拟平扫影像(VNC)的密度进行受试者操作特征(ROC)分析。结果在IM图像上,未来出现梗死区域的密度要高于未来没有出现梗死的区域(23.44±24.86∶5.77±2.77;P<0.000 1),但在VNC影像 Abstract Objective After the recanalization of the artery (IAR), the bleeding and the destruction of the blood-brain barrier (BBB) ​​can be distinguished by dual-energy CT (DECT). This study assesses whether DECT can be used to predict the progression of future infarctions. Methods Twenty-five cases of post-IAR patients were analyzed by DECT scan of 45 BBB destruction areas and compared with the follow-up results. Subject Operating Characteristic (ROC) analysis was performed using the densities of iodine (IM) and virtual scans (VNC) images. Results In the IM images, the density of the future infarction area was higher than that in the future without infarction (23.44 ± 24.86: 5.77 ± 2.77; P <0.0001), but in the VNC images
