【摘要】：目的:探讨MR磁敏感加权成像T2*加权血管成像(SWAN)序列对儿童颅内多发海绵状血管瘤的诊断价值。方法:搜集2012年12月-2015年8月在本院经临床或病理证实的18例颅内多发海绵状血管瘤患儿的病例资料。所有患儿均行常规序列及SWAN序列MRI平扫,12例行增强扫描。由2位有经验的影像诊断医师对所有图像进行评估,分析海绵状血管瘤的影像学特征,并比较SWAN序列与常规序列检出病灶的敏感性。结果:18例共检出285个病灶,其中T1WI发现病灶28个,T2WI发现病灶62个,SWAN序列发现病灶285个。SWAN序列对病灶的检出率高于T1WI和T2WI序列。18例中有4例合并发育性静脉异常,在SWAN序列上显示清晰。结论:MRI是儿童颅内多发海绵状血管瘤的首选影像学检查方法,SWAN序列对海绵状血管瘤以及伴发的发育性静脉异常具有重要的诊断价值。
[Abstract]:Objective: to evaluate the diagnostic value of magnetic sensitive weighted T 2 * weighted angiography (Swan) sequence in intracranial multiple cavernous hemangioma in children. Methods: the data of 18 cases of intracranial multiple cavernous hemangioma confirmed clinically or pathologically in our hospital from December 2012 to August 2015 were collected. All the children underwent conventional sequence and SWAN sequence MRI plain scan 12 cases enhanced scan. The imaging features of cavernous hemangioma were evaluated by two experienced imaging diagnostics and the sensitivity of SWAN sequence to conventional sequence was compared. Results in 18 cases, 285 lesions were detected, of which 28 lesions were detected on T2WI with T1WI, 62 lesions were detected by SWAN sequence, and the detection rate of Swan sequence was higher than that of T1WI and T2WI sequence in 4 out of 18 cases. Display clearly on SWAN sequence. Conclusion the SWAN sequence is the first choice of imaging examination for multiple intracranial cavernous hemangioma in children. Swan sequence is of great value in the diagnosis of cavernous hemangioma and its associated developmental venous abnormalities.
