Standard imaging in acute stroke is undertaken with the aim of diagnosing the underlying cause and excluding stroke mimics. In the presence of ischaemic stroke, imaging is also needed to assess patient suitability for treatment with intravenous thrombolysis. Non-contrast CT is predominantly used, but MRI can also exclude any contraindications to thrombolysis treatment. Advanced stroke imaging such as CT and MR angiography and perfusion imaging are increasingly used in an acute setting. In this review, we discuss the evidence for the application of these advanced techniques in the imaging of acute stroke.
急性中风的标准成像旨在诊断潜在病因并排除类似中风的病症。对于缺血性中风患者,还需要进行成像检查以评估其是否适合静脉溶栓治疗。主要使用非增强CT,但MRI也可排除溶栓治疗的任何禁忌症。诸如CT和MR血管造影以及灌注成像等先进的中风成像技术在急性情况下的应用越来越广泛。在本综述中,我们讨论了这些先进技术在急性中风成像中应用的证据。
