摘　　要：目的：探讨非增强磁共振血管成像（NCE-MRA）在类风湿性关节炎患者手动脉成像中的应用价值。方法选取2013年1月~2014年12月于我院就诊的32例类风湿性关节炎患者作为研究对象。所有患者均进行手动脉NCE-MRA及增强磁共振血管成像（CE-MRA）。比较两种检查方法的图像信噪比（SNR）、对比度噪声比（CNR）及血管边缘锐利度，评估两组图像质量并进行统计学分析。结果 NCE-MRA组的血管锐利度、SNR、CNR均较CE-MRA组高，且差异有统计学意义（P〈0.05）。NCE-MRA组的图像质量显著高于CE-MRA组（P〈0.05）。结论 NCE-MRA可清晰显示类风湿性关节炎患者的手动脉，且各个动脉部位的SNR、CNR、血管边缘锐利度均高于CE-MRA组，值得推广。Objective To investigate the effectiveness of application of non-contrast enhanced magnetic resonance angiography （NCE-MRA） in hand artery imaging in patients with rheumatoid arthritis （RA）.Methods Altogether 32 RA patients who had been treated in the hospital from January 2013 to December 2014 were selected as the research object. All patients were scanned by hand artery NCE-MRA and contrast-enhanced magnetic resonance angiography （CE-MRA）. And then the signal-to-noise ratio （SNR）, signal-to-noise ratio （CNR） and vascular edge sharpness of the NCE-MRA and CE-MRA imaging results were compared. Additionally, image quality was evaluated and statistically compared. Results The vascular edge sharpness, SNA and CNR in NCE-MRA Group were higher than that in CE-MRA Group with statistically signiifcant differences （P〈0.05）. The image quality in NCE-MRA Group were obviously better than that in CE-MRA Group with statistically signiifcant differences （P〈0.05）. Conclusion Application of non-contrast enhanced magnetic resonance angiography in patients with rheumatoid arthritis could improve the imaging quality of the hand artery segments. And SNR, CNR as well as the vascular edge sharpness of NCE-MRA at each artery location were higher than those of CE-MRA, which showed its higher diagnostic effectiveness and deserved promotion.
