摘要
目的探讨高分辨MRI不同序列检查评价缺血性脑血管病患者颈动脉粥样硬化斑块成分的临床意义。方法选择64例缺血性脑血管病患者,其中短暂性脑缺血发作(TIA)患者18例,脑梗死患者46例。采用头颈联合线圈,行高分辨MRI检查,先后选用三维时间飞跃法、T_1WI、T_2WI和质子加权成像4种不同序列,分析斑块成分。结果 64例患者中,有完整厚纤维帽25例(39.1%)、完整薄纤维帽20例(31.2%)、破损纤维帽19例(29.7%),脂质池和坏死核心53例(82.8%),斑块内钙化44例(68.8%),斑块内出血31例(48.4%),斑块内纤维化33例(51.6%),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(P>0.05)。结论高分辨MRI不同序列检查对颈动脉斑块的检测有助于分析斑块的成分特征,确定斑决的稳定性。
Objective To investigate high resolution MRI sequence signal characteristics of the fibrous cap and the intraplaque components of carotid atherosclerotic praque. Methods Four high resolution MRI sequences were used to analyze the carotid atheroscterotic plaques of 64 patients with carotid atherosclerotic plaque. The sequences used included 3D-TOF, T1WI, T2WI and PDWI. The patients were divided into transient ischemic attack（TIA） group containing 18 patients and cerebral infarction（CI） group containing 46 patients. Results Of the sixty-four patients,twenty-five had thick fibrous caps, twenty had thin fibrous caps, nineteen had ruptured fibrous caps,fifty-three had lipid-rich necrotic cores, forty-four had calcification, thirty-one had intraplaque haemorrhage, thirty-three had fibrous tissue in the plaque. There was no statistic differ ence in plaque composition between the two groups . Conclusion The high resolution MRI can be used to examine the morphology and components of the plaque.
