治疗前缺血核心体积在概念上等于成功再通患者的随访梗死体积（FIV）。然而，治疗前核心体积和FIV之间有时存在绝对体积差（AD）。目的是比较贝叶斯和奇异值分解（SVD）方法之间的AD值与急性缺血性卒中（AIS）患者接受机械血栓切除术的时间从发病到成像。（颈内动脉或大脑中动脉）;（2）发病24小时内;（3）治疗前CT灌注（CTP）;（4）成功再通（mTICI ≥ 2b）;（5）24小时弥散加权成像（DWI）。在24小时DWI上测量FIV。采用贝叶斯和SVD方法计算FIV和处理前核心体积之间的AD值。斯皮尔曼的等级相关系数（rho）计算为appropriate.ResultsIn的47例患者（25名男性，中位年龄78岁，中位数基线国立卫生研究院卒中量表，22），发病至成像和发病至再通的中位时间分别为136和220分钟。较短的发作至成像时间与较大的AD值相关，SVD方法（rho =-0.28，p = 0.05）与贝叶斯方法（rho =-0.08）相比，观察到更多的趋势。更大的预处理核心体积与更大的AD值相关，并且SVD（rho = 0.63，p < 0.01）的这种趋势比Bayesian（rho = 0.32，p = 0.03）方法稍强。
PurposePretreatment ischemic core volume is conceptually equal to follow-up infarct volume (FIV) in patients with successful recanalization. However, there is sometimes an absolute volume difference (AD) between pretreatment core volume and FIV. The aim was to compare the AD values between the Bayesian and the singular value decomposition (SVD) methods with time from onset-to-imaging in acute ischemic stroke (AIS) patients undergoing mechanical thrombectomy.MethodsConsecutive AIS patients were included if they had the following: (1) anterior large vessel occlusion (internal carotid or middle cerebral artery); (2) within 24 h of onset; (3) pretreatment CT perfusion (CTP); (4) successful recanalization (mTICI ≥ 2b); and (5) 24-h diffusion-weighted imaging (DWI). FIV was measured on 24-h DWI. The AD value between FIV and the pretreatment core volume was calculated for Bayesian and SVD methods. Spearman’s rank correlation coefficient (rho) was calculated as appropriate.ResultsIn the 47 patients enrolled (25 men; median age 78 years; median baseline National Institutes of Health Stroke Scale, 22), the median time from onset-to-imaging and onset-to-recanalization was 136 and 220 min, respectively. Shorter onset-to-imaging time was correlated with a larger AD value, and more trend was seen in the SVD method (rho = − 0.28,p= 0.05) compared with the Bayesian method (rho = − 0.08). A larger pretreatment core volume was correlated with a larger AD value, and this tendency was slightly stronger for the SVD (rho = 0.63,p< 0.01) than for the Bayesian (rho = 0.32,p= 0.03) method.ConclusionsThe Bayesian method might be more correlated with FIV than the SVD method in patients with a large ischemic lesion immediately after stroke onset, but not perfect.
