Until recently, there was no efficacious treatment for acute cerebral ischemia. As a result, the role of neuroimaging and the radiologist was peripheral in the diagnosis and management of this disease. The demonstration of efficacy using thrombolysis has redefined this role, with the success of intervention becoming increasingly dependent on timely imaging and accurate interpretation. The potential benefits of intervention have only begun to be realized. In this State-of-the-Art review of imaging of acute stroke, the role of imaging in the current and future management of stroke is presented. The role of computed tomography is emphasized in that it is currently the most utilized technique, and its value has been demonstrated in prospective clinical trials. Magnetic resonance techniques are equally emphasized in that they have the potential to provide a single modality evaluation of tissue viability and vessel patency in an increasingly rapid evaluation.
直到最近，急性脑缺血仍没有有效的治疗方法。因此，神经影像学及放射科医生在该疾病的诊断和治疗中处于边缘地位。溶栓治疗有效性的证明重新定义了这一角色，干预的成功越来越依赖于及时的影像学检查和准确的解读。干预的潜在益处才刚刚开始显现。在这篇关于急性卒中影像学的前沿综述中，阐述了影像学在当前及未来卒中治疗中的作用。计算机断层扫描的作用得到强调，因为它是目前使用最广泛的技术，其价值已在前瞻性临床试验中得到证实。磁共振技术也同样得到强调，因为它们有潜力在越来越快速的评估中对组织活力和血管通畅性进行单一模式评估。
