BACKGROUND/OBJECTIVES: The impact of stroke location and volume on the development of post-stroke dysphagia is not fully understood. The aim of this study is to evaluate the relationship between acute ischemic lesions and the severity of dysphagia.
Brain MRIs were obtained with a 1.5 Tesla MRI system (Magnetom Avanto B13, Siemens, Erlangen, Germany). The brain MRI protocol included axial echo planar diffusion-weighted imaging (DWI). The acute ischemic volume was obtained using DWI by drawing regions of interest (ROIs). The diagnosis and assessment of the severity of dysphagia was carried out by a multidisciplinary team and included the Dysphagia Outcome and Severity Scale (DOSS), the Penetration-Aspiration Scale (PAS), and the Pooling score (P-score). The threshold for statistical significance was set at 5%.
Among all the patients enrolled ( = 64), 28 (43.8%) were males and 36 (56.2%) were females, with a mean age of 78.8 years. Thirty-three (51.6%) of them had mild dysphagia and thirty-one (48.4%) had moderate-severe dysphagia. The total ischemic volume was negatively correlated with the DOSS (r = -0.441, = 0.0003) and positively with the P-score (r = 0.3054, = 0.0328).
There are significant associations between the severity of dysphagia and the quantitative DWI-based data of the acute ischemic volume and anatomical location.
背景/目的：卒中部位和体积对卒中后吞咽困难发展的影响尚未完全明确。本研究旨在评估急性缺血性病灶与吞咽困难严重程度之间的关系。
使用1.5特斯拉磁共振成像系统（德国西门子公司埃尔兰根产Magnetom Avanto B13）获取脑部磁共振成像。脑部磁共振成像方案包括轴向回波平面扩散加权成像（DWI）。通过绘制感兴趣区域（ROI），利用DWI获取急性缺血体积。吞咽困难的诊断和严重程度评估由多学科团队进行，包括吞咽困难结果和严重程度量表（DOSS）、渗透-误吸量表（PAS）和积聚评分（P评分）。统计学显著性阈值设定为5%。
在所有纳入的患者（n = 64）中，男性28例（43.8%），女性36例（56.2%），平均年龄78.8岁。其中33例（51.6%）有轻度吞咽困难，31例（48.4%）有中度至重度吞咽困难。总缺血体积与DOSS呈负相关（r = -0.441，P = 0.0003），与P评分呈正相关（r = 0.3054，P = 0.0328）。
吞咽困难的严重程度与基于DWI的急性缺血体积定量数据及解剖位置之间存在显著关联。
