磁共振磁敏感加权序列对儿童脑内海绵状血管瘤的诊断价值

Diagnostic value of magnetic resonance sensitive weighted sequence in children with intracerebral cavernous hemangioma

目的探讨磁共振磁敏感加权(SWI)序列对儿童脑内海绵状血管瘤的诊断价值。方法回顾性分析2017年8月至2018年8月河南省儿童医院经病理证实并于术前进行颅脑磁共振常规及SWI序列扫描的颅内海绵状血管瘤患者22例,分析其磁共振常规序列及SWI序列影像表现。结果22例患儿于T_(1)加权序列(T_(1)WI)发现病灶数28个,病灶直径为0.5~11.2 mm,平均(6.4±1.8)mm;于T_(2)加权序列(T_(2)WI)发现病灶数35个,病灶直径为0.5~14.6 mm,平均(7.1±1.7)mm;于SWI序列发现病灶数为66个,病灶直径为0.5~25.8 mm,平均(14.3±1.8)mm;T_(1)WI与T_(2)WI序列病灶平均直径相比较,差异无统计学意义(P>0.05),SWI与T_(1)WI、T_(2)WI序列病灶平均直径相比较,差异有统计学意义(P<0.05)。结论磁共振SWI序列较常规序列更能清楚显示儿童颅内海绵状血管瘤病灶。

Objective To investigate the diagnostic value of magnetic resonance sensitivity weighted(SWI)sequence in children with intracerebral cavernous hemangioma.Methods RRetrospective analysis was performed on 22 patients with intracranial cavernous hemangioma who were pathologically confirmed and underwent routine craniocerebral MRI and SWI sequence scanning before surgery in Henan Children′s Hospital from August 2017 to August 2018,The imaging manifestations of their routine MRI sequence and SWI sequence were analyzed.Results A total of 28 lesions were found on T_(1)-weighted sequence(T_(1)WI)in 22 children,with a diameter of 0.5~11.2 mm and an average of(6.4±1.8)mm;A total of 35 lesions were found on T_(2)-weighted sequence(T_(2)WI)with a diameter of 0.5~14.6 mm,with an average of(7.1±1.7)mm;The number of lesions detected in SWI sequence was 66,with a diameter of 0.5~25.8 mm,with an average of(14.3±1.8)mm.There was no statistically significant difference in the mean diameter of T_(1)WI and T_(2)WI sequences(P>0.05);SWI was compared with the mean diameter of T_(1)WI and T_(2)WI sequence lesions,The difference was statistically significant(P<0.05).Conclusion Compared with conventional MRI SWI sequences,the lesions of intracranial cavernous hemangioma in children could be clearly displayed.
