N Engl J Med:起搏器或者除颤器的患者有望做磁共振成像检查

2017-02-23 MedSci MedSci原创

心血管系统植入的电子装置长期以来一直是磁共振成像(MRI)的检查的禁忌。日前在新英格兰杂志上,Russo RJ等研究者通过前瞻性研究发现,在磁场强度为1.5特斯拉下,患者植入MRI禁忌的电子装置在接受非胸部MRI扫描时,没有发现装置或者线路故障。该前瞻性研究入组的患者将接受非胸部、磁场强度为1.5特斯拉的MRI检查。在MRI扫描前,电子装置的使用标准方案将被问询并进行适当的重新编程。该研究设立的主

心血管系统植入的电子装置长期以来一直是磁共振成像(MRI)的检查的禁忌。日前在新英格兰杂志上,Russo RJ等研究者通过前瞻性研究发现,在磁场强度为1.5特斯拉下,患者植入MRI禁忌的电子装置在接受非胸部MRI扫描时,没有发现装置或者线路故障。

该前瞻性研究入组的患者将接受非胸部、磁场强度为1.5特斯拉的MRI检查。在MRI扫描前,电子装置的使用标准方案将被问询并进行适当的重新编程。该研究设立的主要终点是死亡,发生器或线路故障,包括诱发的心律失常,丧失起搏功能或在扫描期间的电复位。次要终点是设备设置的更改。

该研究收录了1000例植入心脏起搏器及500例植入复律-除颤器(ICD)患者。MRI扫描过程中,结果没有死亡、线路故障、丧失起搏功能或室性心律失常发生。只有一个ICD因为MRI扫描前不能被适当重新编程导致扫描后需要立即更换。另外发现6例发生可转复性房颤或房扑和6例发生部分电复位。在少数情况下,导线阻抗、起搏阈值、电池电压以及P波和R波幅度的变化超过了预定的阈值。重复MRI与不良事件的增加无关。

综上,患者心脏植有电子装置,可不再是MRI检查的绝对禁忌症。其也将有机会接受非胸部,磁场强度为1.5特斯拉的MRI检测。

几秒钟之内可测量脑龄,或将带来糖尿病、精神分裂症临床新疗法

使用MRI扫描来确定脑龄一直是一个非常耗时的过程。现在,AI机器只需要几秒钟就可以完成检测。人类的认知能力会随着年龄增长而衰退。神经科学家也早已发现,这种衰退与大脑解剖结构的变化有关。毫无疑问,大脑MRI图像无法指示衰老迹象,更不用说确定“大脑年龄”。大脑年龄和实足年龄之间的差异可以揭示痴呆症等病症发作情况。几秒钟之内获得准确的脑龄数据然而,MRI图像分析是一个冗长的过程,因为MRI数据必须经过大
