Ischemic diffusion-weighted imaging-fluid-attenuated inversion recovery (DWI-FLAIR) mismatch may be useful in guiding acute stroke treatment decisions given its relationship to onset time and parenchymal viability; however, it relies on subjective grading. Radiomics is an emerging image quantification methodology that may objectively represent continuous image characteristics. We propose a novel radiomics approach to characterize DWI-FLAIR mismatch.

大血管闭塞性卒中中 DWI-FLAIR 不匹配的放射学特征

缺血性弥散加权成像流体衰减反转恢复 (DWI-FLAIR) 不匹配可能有助于指导急性卒中治疗决策，因为它与发病时间和实质活力有关；但是，它依赖于主观评分。放射组学是一种新兴的图像量化方法，可以客观地表示连续的图像特征。我们提出了一种新的放射组学方法来表征 DWI-FLAIR 失配。
