参数优化磁敏感加权成像对急性缺血性脑卒中的诊断价值
Diagnostic value of parameter-optimized susceptibility-weighted imaging in acute ischemic stroke
摘要
Abstract
Objective To investigate the diagnostic value of parameter-optimized susceptibility-weighted imaging(SWI)in acute ischemic stroke(AIS).Methods Sixty AIS patients who met the inclusion criteria and were treated in Guangxi Zhuang Autonomous Region Ethnic Hospital from January 2020 to December 2023 were collected.Each patient underwent SWI examination with two sets of parameters and obtained two sets of images.The conventional parameter sequence was the control group,and the parameter-optimized sequence was the experimental group.The detection rate of important signs,scanning time,and image quality of the two groups of images were compared.Results Thirty-nine patients with positive CMBs were detected in both groups,showing 92 intracerebral hemorrhage foci,including 18 hemorrhage transformed(HT)foci within infarction foci,and 74 cerebral microbleeds(CMBs)foci outside the infarction foci.Nine cases of magnetically susceptibility vascular sign(SVS)were detected in both groups,which was in line with the site of vascular occlusion shown by MRA.Twenty-three cases of prominent vessel sign(PVS)were detected in both groups,which was in line with the area of hypoperfusion shown by three-dimensional arterial spin labeling(3D-ASL)showing hypoperfusion areas.The scanning time of the control group was 294 s,and that of the experimental group was 145 s.The image quality score of the experimental group was 3.27±0.15,which of the control group was 3.65±0.25,and the difference was statistically significant(P＜0.05),but the scores of the experimental group were all higher than 3,and the image quality met the diagnostic requirements.Conclusion SWI is a very valuable imaging sequence,which can provide important complementary information about AIS patients,and can identify various imaging features with prognostic value and affecting treatment decisions.The SWI optimized by parameters can be performed in only 145 s and can be included in the MR I imaging sequence of emergency examination of AIS patients.关键词
