摘要
目的使用受试者操作特征(ROC)曲线分析评价彩色多普勒超声(CDU)与三维动态增强磁共振血管造影(3DDCE-MRA)对膝以下动脉硬化性闭塞的诊断价值。方法41例小腿动脉硬化性闭塞患者,其中男性34例,女性7例;年龄48～83岁,平均年龄69.10岁。经CDU及3DDCE-MRA检查,与数字减影血管造影检查(DSA)和/或手术相对照。结果3DDCE-MRA诊断膝以下动脉硬化性闭塞、重度狭窄的Az值分别为0.7646、0.7745;CDU诊断膝以下动脉硬化性闭塞、重度狭窄的Az值分别为0.9526、0.9053。从ROC曲线可见膝以下动脉硬化性闭塞的准确度CDU诊断优于3DDCE-MRA。结论对于膝以下动脉硬化性闭塞的患者,CDU是简便易行且准确的检查方法,优于3DDCE-MRA。
Objective To investigate the value of color Doppler ultrasound（CDU） and three-dimensional dynamic contrastenhanced magnetic resonance angiography（3D DCE-MRA） in the diagnosis of arteriosclerosis obliterans in calf artery by receiver operating characteristic（ROC） analysis.Methods Forty-one patients with lower extremity arterial occlusive disease were enrolled,male 34,female 7,aged 48-83 years,mean age 69.10 years.They were examined by CDU and 3D DCE-MRA.The obtained results were compared with DSA and/or surgery.Results The ROC analysis indicated that the detection of occlusive and significant arterial stenosis disease in calf by 3D DCE-MRA was 0.764 6（Az）,0.774 5（Az）,and by CDU was 0.952 6（Az）,0.905 3（Az） respectively.Conclusion The CDU is superior to 3D DCE-MRA in diagnosing of arteriosclerosis obliterans below knee.
