CTA联合CE-MRA在诊断下肢动脉病变中的应用价值

目的:探讨CT血管成像技术(CTA)联合增强磁共振血管成像(CE-MRA)在诊断下肢动脉病变中的应用价值.方法:选取2019年1月～2020年12月在本院确诊的87例下肢动脉病变患者,同期选取98例非下肢动脉病变患者,进入实验.两组患者均接受血管数字减影(DSA)并以其为金标准,并行CTA与CE-MRA检查,比较CTA...

The Value of CTA Combined with CE-MRA in the Diagnosis of Lower Extremity Artery Disease

Objective:To explore the value of CTA combined with CE-MRA in the diagnosis of lower extremity artery disease.Methods:87 patients with lower extremity artery disease diagnosed from January 2019 to December 2020 were selected in our hospital.98 patients with non lower extremity artery disease were selected at the same time.Both groups were treated with DSA and taken them as gold standard.CTA and CE-MRA were performed in parallel.Sensitivity and specificity of CTA and CE-MRA were compared in the diagnosis and joint diagnosis of the lesions of the superior knee artery,the inferior knee artery and the dorsal foot artery Degree and Youden index.Results:The sensitivity of CTA combined with CE-MRA in the diagnosis of lower extremity artery disease was higher than that of CTA and CE-MRA alone,and the differences were statistically significant(P<0.05);The Youden index of CTA combined with CE-MRA was higher than that of CTA and CE-MRA alone.Conclusion:CTA and CE-MRA have certain clinical value in the diagnosis of lower extremity artery disease,but the sensitivity,specificity and Youden index of CTA and CE MRA can be increased by the combination of the two diagnosis.
