目的：探讨急性大面积脑梗死侧枝循环的磁敏感加权成像（susceptibility-weighted imaging, sWi）的表现及其与临床评分的相关性。材料和方法选择46例急性大面积脑梗死患者（临床症状出现24小时以内）进行常规Mri和sWi检查，并在2周，3个月内进行复查。对急性大面积脑梗死周围侧枝血管的显示程度进行分级。得出相应临床niHss评分，并与sWi显示程度进行相关统计学分析。结果有34例显示梗死周围侧枝血管的存在，占比例为74%。其中ii级显示16例（占35%），i级显示18例（占39%），0级显示12例（占26%）显示程度与临床niHss评分改变有正相关性（rs=0.696, P<0.01）。结论急性大面积脑梗死侧枝血管在sWi的表现具有一定特点；量化分析侧枝血管的显示程度，有助于判断急性大面积脑梗死侧枝循环情况，对评价患者预后具有一定的指导作用。
目的：探討急性大麵積腦梗死側枝循環的磁敏感加權成像（susceptibility-weighted imaging, sWi）的錶現及其與臨床評分的相關性。材料和方法選擇46例急性大麵積腦梗死患者（臨床癥狀齣現24小時以內）進行常規Mri和sWi檢查，併在2週，3箇月內進行複查。對急性大麵積腦梗死週圍側枝血管的顯示程度進行分級。得齣相應臨床niHss評分，併與sWi顯示程度進行相關統計學分析。結果有34例顯示梗死週圍側枝血管的存在，佔比例為74%。其中ii級顯示16例（佔35%），i級顯示18例（佔39%），0級顯示12例（佔26%）顯示程度與臨床niHss評分改變有正相關性（rs=0.696, P<0.01）。結論急性大麵積腦梗死側枝血管在sWi的錶現具有一定特點；量化分析側枝血管的顯示程度，有助于判斷急性大麵積腦梗死側枝循環情況，對評價患者預後具有一定的指導作用。

Objective To investigate the performance of SWI in the collateral circulation of acute massive cerebral infarction and its relevance with clinical scores. Methods 46 patients with acute massive cerebral infarction (clinical symptoms occurred with 24h) were performed with routine MRI and SWI examination, and followed up in the 2 weeks and 3 months. The display degree of collateral vessels of the acute massive cerebral infarction were classified. And the clinical NIHSS scores were got to analyze its correlation with the SWI display degree. Results The collateral vessels were revealed by SWI in 34 cases, in the proportion of 74%. 16 cases were showed in grade II (35%), 18 cases were showed in grade I (39%), 12 cases were showed grade 0 (26%). There was a positive correlation between the display degree of collateral circulation in the SWI and the NIHSS scores changes (rs=0.696, P <0.01). Conclusion The collateral vessels of acute massive cerebral infarction showed certain characteristics on SWI. By which the display degree of collateral vessels were quantitatively analyzing, it was helpful in evaluating the condition of collateral circulations of the acute massive cerebral infarction and for guiding the evaluation of the clinical prognosis of patients.
