【摘要】：目的探讨高分辨磁共振成像(HRMRI)下颅内未破裂动脉瘤瘤壁环形强化(CAWE)的临床意义。方法选取2014年10月至2015年6月收治的接受钆剂增强HRMRI检测的颅内未破裂动脉瘤患者28例,其中有症状患者13例(警示性头痛8例,患侧动眼神经麻痹5例),无症状患者15例。2名影像科医师独立阅片,确定是否出现CAWE。结果检测发现28例患者31枚颅内未破裂动脉瘤。根据Kappa一致性检验,2名影像科医师诊断CAWE结果有较高一致性(Kappa=0.7427,95%CI:0.51~0.98)。13例有症状患者14枚动脉瘤中11枚(11/14,78.6%)出现CAWE,15例无症状患者17枚动脉瘤中5枚(5/17,29.4%)出现CAWE,两者间差异有统计学意义(P=0.0113)。结论钆剂增强HRMRI检测显示有症状颅内未破裂动脉瘤患者CAWE明显较无症状患者多见,提示动脉瘤未来破裂的可能性较高。
[Abstract]:Objective to investigate the circular enhancement of intracranial unruptured aneurysms with HRMRI under high resolution magnetic resonance imaging (HRMRI). Methods from October 2014 to June 2015, 28 patients with intracranial unruptured aneurysms underwent gadolinium-enhanced HRMRI examination. There were 13 cases of symptomatic patients (8 cases of warning headache, 5 cases of oculomotor nerve palsy on the affected side and 15 cases of asymptomatic patients. Results 31 intracranial unruptured aneurysms were found in 28 patients. According to Kappa consistency test. There was a high consistency in the diagnosis of CAWE between 2 radiologists and 0.7427. CAWE was found in 11 of 14 aneurysms in 13 symptomatic patients. CAWE was found in 5 of 17 aneurysms in 15 asymptomatic patients. Conclusion Gadolinium-enhanced HRMRI is more common in patients with symptomatic intracranial unruptured aneurysms than in asymptomatic patients. The results suggest that the possibility of aneurysm rupture in the future is higher.
