【摘要】：目的分析急性大面积脑梗死患者血栓的磁敏感加权成像(SWI)特点及其与临床的相关性。方法选择46例急性大面积脑梗死(临床症状出现24 h)患者进行SWI检查,并在2周、3个月进行随诊。分析急性大面积脑梗死血栓的SWI图像特点,并得出相应美国国家健康研究所脑卒中分级量表(NIHSS)评分,进行相关统计学分析。结果有34例显示血栓存在,占74%。其中急性期和亚急性期(2周)显示32例,稳定恢复期(3个月)显示2例,不同时期内血栓的显示特点差异有统计学意义(P0.05)。其中血栓长度≥4 cm 23例,血栓长度与临床NIHSS评分有相关性(r=0.783,P0.01)。血栓位于梗死血管起始部26例,远侧部8例,血栓的位置与临床NIHSS评分有相关性(r=0.747,P0.01)。结论 SWI对无创显示急性大面积脑梗死血管内血栓具有敏感性和特异性;量化分析有助于判断急性大面积脑梗死的演变情况,对临床治疗及预后评估起到一定的指导作用。
[Abstract]:Objective to analyze the characteristics of magnetic sensitivity weighted imaging (SWI) and its correlation with clinical manifestations in patients with acute large area cerebral infarction. Methods 46 patients with acute large area cerebral infarction (24 hours after clinical symptoms) were examined by SWI. The characteristics of SWI images of acute large area cerebral infarction thrombosis were analyzed and the corresponding NIHSS scores were obtained by the stroke grading scale of the National Institute of Health of the United States of America. Results there were 34 cases of thrombus, accounting for 74%. Among them, 32 cases were found in acute and subacute phase (2 weeks), and 2 cases in stable recovery period (3 months). There were significant differences in the characteristics of thrombus in different periods (P 0.05), among which 23 cases had thrombus length 鈮，
