·综述·SWI脑微出血征临床相关研究进展张良，谭洋，韩芳，王斌内蒙古民族大学第二临床医学院影像科内蒙古牙克石022150【摘要】脑微出血(CMBs)常见于卒中等脑血管疾病患者，是较为常见的神经影像征象。CMBs的病理生理过程以及发生机制尚未完全明确，可能继发于慢性高血压血管壁损伤或组织淀粉样蛋白沉积。CMBs的存在增加了卒中、痴呆和死亡的风险，随着CMBs数量的增加，溶栓、抗凝或抗血小板等治疗可能会导致急性缺血性卒中(AIS)患者出血并发症的风险增加，然而，CMBs的存在并不是抗凝或溶栓的用药禁忌。磁敏感加权成像(SWI)依靠其对血液成分、钙化、铁沉积等显示优势，在AIS等脑血管疾病的诊断及评估中发挥着独特作用。本文就目前对SWI脑微出血的认识及其在AIS治疗的评估价值进行综述。【关键词】急性缺血性脑卒中;脑微出血;磁共振成像中图分类号:Ｒ741．04;Ｒ445．2文献标识码:A文章编号:1006-9011(2023)04-0641-04ClinicalprogressofSWIcerebralmicrobleedsZHANGLiang，TANYang，HANFang，WANGBinDepartmentofＲadiology，TheSecondClinicalMedicineFaculty，InnerMongoliaNationalitUniversity，Yakeshi022150，China【Abstract】Cerebralmicrobleeds(CMBs)arecommonneuroimagingsignsinpatientswithcerebrovasculardiseasessuchasstroke．ThepathophysiologicalprocessandpathogenesisofCMBshavenotbeencompletelyclarified，andmaybesecondarytovascularwalldamageortissueamyloiddepositioninchronichypertension．ThepresenceofCMBsincreasestheriskofstroke，de-mentia，anddeath．AsthenumberofCMBsincreases，thrombolytic，anticoagulant，orantiplatelettherapiesmayincreasetheriskofbleedingcomplicationsinpatientswithacuteischemicstroke(AIS)．However，thepresenceofCMBsisnotacontraindicationforanticoagulantorthrombolytictherapy．Susceptibilityweightedimaging(SWI)playsauniqueroleinthediagnosisandevalua-tionofcerebrovasculardiseasessuchasAISduetoitsadvantagesinshowingbloodcomposition，calcificationandirondeposition．ThisarticlereviewsthecurrentnaturalunderstandingofmagneticsensitivityweightedimagingofCMBsanditsapplicationinAIStreatmentevaluation．【Keywords】Acuteischemicstroke;Cerebralmicrobleeds;Magneticresonamceimaging磁敏感加权成像(susceptibilityweightedimaging，SWI)早期被叫...
