Patients with acute ischemic stroke due to a large vessel occlusion (AIS-LVO) undergo emergent neuroimaging triage for thrombectomy treatment. MRI is often utilized for this evaluation, and cerebral magnetic resonance perfusion (MRP) imaging is used to identify the presence of the salvageable penumbra. To determine if dose reduction is feasible, we assessed whether a half-dose reduction in gadobenate provided sufficient MRP quality in AIS-LVO patients.

MR 灌注成像：半剂量钆是质量的一半

由于大血管闭塞 (AIS-LVO) 导致的急性缺血性卒中患者接受紧急神经影像学分诊以进行血栓切除术治疗。MRI 通常用于此评估，并且脑磁共振灌注 (MRP) 成像用于识别可挽救半暗带的存在。为了确定剂量减少是否可行，我们评估了钆苯酸盐的半剂量减少是否为 AIS-LVO 患者提供了足够的 MRP 质量。
