摘要
目的:探讨3.0T MRI高分辨多序列成像评价颈动脉粥样硬化斑块成分的临床意义。方法:选择58例缺血性脑血管病患者,其中短暂性脑缺血发作(TIA)患者16例,脑梗死患者42例;运用3.0T MRI多序列(3D-TOF、DIR T1WI、FSE T2WI、PDWI)进行扫描,分析斑块成分。结果:58例患者中,17例(29.3%)有破损纤维帽,23例(39.7%)有完整厚纤维帽、18例(31.0%)有完整薄纤维帽;29例(50.0%)有斑块内出血,27例(46.6%)有斑块内钙化,42例(72.4%)有斑块内纤维化,49例(84.5%)有脂质池和坏死核心,脑梗死患者与TIA患者各类斑块成分所占比例比较,差异均无统计学意义(>005)。结论:3.0T MRI高分辨多序列成像有助于分析颈动脉粥样硬化斑块的成分,判断斑块的稳定性。
Objective： To investigate 3.0T MRI sequence signal characteristics of the intraplaque components of carotid atherosclerotic praque.Methods：Four 3.0T MRI sequences were used to analyze the carotid atherosclerotic plaques of 58 patients with carotid atherosclerotic plaque.The sequences used included 3D-TOF,DIR T1 WI,FSE T2 WI and PDWI.The patients were divided into transient ischemic attack（TIA） group containing 16 patients and cerebral infarction（CI）group containing 42 patients.Results：Of the 58 patients,17 had ruptured fibrous caps,23 had thick fibrous caps,18 had thin fibrous caps,29 had intra plaque haemorrhage,27 had calcification,42 had fibrous tissue in the plaque,49 had lipid rich necrotic cores.There was no statistic difference in plaque composition between the two groups.Conclusion：3.0 T MRI high resolution sequence image was helpful to analyzing the composition of carotid atherosclerotic plaques,judging the stability of the plaques.
