摘　　要：目的对比磁敏感加权成像(susceptibility weighted imaging,SWI)与常规磁共振成像(magnetic resonance imaging,MRI)序列对脑海绵状血管瘤(cerebral cavernous malformations,CCM)的诊断价值。方法选取吉林市中心医2021年12月—2022年12月收治的75例CCM患者为研究对象,对所有患者进行SWI和MRI检查,对比CCM患者SWI和MRI常规序列(T1WI、T2WI)的差异。结果75例CCM患者SWI阳性率高于MRI-T1WI和MRI-T2WI,存在显著差异(P<0.05);SWI、MRI-T1WI和MRI-T2WI病灶平均直径分别为5.24、4.86、4.98 mm,SWI显示病灶平均直径的精准度高于MRI-T1WI和MRI-T2WI,具有显著差异(P<0.05)。结论SWI可反映CCM患者的具体疾病情况,提高疾病的诊断效能,更好地指导疾病的诊断和治疗。Objective To compare the diagnostic value of magnetic sensitivity weighted imaging(SWI)and conventional magnetic resonance imaging(MRI)sequences in cerebral cavernous hemangiomas(CCM).Methods Seventy five CCM patients admitted to Jilin Central Hospital from December 2021 to December 2022 were selected as the study subjects.All patients were examined by SWI and MRI,and the difference between SWI and conventional MRI sequences(T1WI,T2WI)of CCM patients was compared.Results The positive rate of SWI in 75 CCM patients was higher than that on MRI-T1WI and MRI-T2WI,with a significant difference(P<0.05);The average diameter of lesions on SWI,MRI-T1WI,and MRI-T2WI was 5.24,4.86,and 4.98 mm,respectively.The accuracy of SWI in displaying the average diameter of lesions was higher than that on MRI-T1WI and MRI-T2WI,with a significant difference(P<0.05).Conclusion SWI can reflect the specific disease situation of CCM patients,improve the diagnostic efficiency of the disease,and better guide the diagnosis and treatment of the disease.
