背景：在急性缺血性卒中(AIS)中，当发病时间未知时，液体衰减反转恢复(FLAIR)被用于治疗决策。目的：比较合成FLAIR和真实FLAIR对发病4.5h内患者的DWI-FLAIR失配估计和识别的性能。材料和方法：在这项回顾性研究中，所有的治疗和早期随访(=.99)。结论：合成液体衰减反转恢复(FLAIR)在描述弥散加权成像-FLAIR失配和帮助识别早期急性缺血性卒中方面具有与真实FLAIR相似的诊断性能，可能会加速MRI的进程。(C)RSNA，2022年
Background: In acute ischemic stroke (AIS), fluid-attenuated inversion recovery (FLAIR) is used for treatment decisions when onset time is unknown. Synthetic FLAIR could be generated with deep learning from information embedded in diffusion-weighted imaging (DWI) and could replace acquired FLAIR sequence (real FLAIR) and shorten MRI duration.Purpose: To compare performance of synthetic and real FLAIR for DWI-FLAIR mismatch estimation and identification of patients presenting within 4.5 hours from symptom onset.Materials and Methods: In this retrospective study, all pretreatment and early follow-up (=.99).Conclusion: Synthetic fluid-attenuated inversion recovery (FLAIR) had diagnostic performances similar to real FLAIR in depicting diffusion-weighted imaging-FLAIR mismatch and in helping to identify early acute ischemic stroke, and it may accelerate MRI protocols.
