目的：探讨腹带使用对自由呼吸状态下3T MRI 全心对比增强冠状动脉成像图像质量的影响。方法对29例志愿者行3T MRI 全心对比增强成像,26例完成检查,使用不平衡最小指数法将研究对象分为2组：A 组(n=13)使用腹带；B 组(n=13)不使用腹带。结果不使用腹带,全心成像冠状动脉节段显示率为81.9%(149/182)；使用腹带冠状动脉节段显示率为84.4%(189/224)。右冠状动脉段落显示率差异有统计学意义(χ2=6.389,P =0.014)。前降支段落显示率差异有统计学意义(χ2=5.764,P =0.016),回旋支段落显示率差异无统计学意义(χ2=2.378,P =0.145)。组间性别及年龄差异无统计学意义。结论在全心对比增强 MR 冠状动脉成像中,使用腹带有助于控制呼吸,提高图像质量。

Objective To study the influence of using bellyband in 3T contrast-enhanced whole heart coronary magnetic reso-nance.Methods A total of 29 volunteers scheduled for physical exams were prospectively recruited in 3T magnetic resonance coro-nary artery,and 26 of them finished the exam successfully.They were divided into two groups with minimum unbalance index meth-od,A group (n=13)using the belly belt;B group (n=13)without belly belt.Results The coronary artery segment display rate was 81.9% (149/182)without the bellyband,while the rate was 84.4% (189/224)with the bellyband.The display rate of right coronary artery segments was significant different (χ2 =6.389,P =0.014),the display rate of left anterior descending artery seg-ments was significant different (χ2 = 5.764,P = 0.01 6 ),the circumflex segments display showed no significant different (χ2 =2.378,P =0.145).It is non-statistics significance between sex and age of groups.Conclusion The image quality is much better on contrast-enhanced whole-heart coronary magnetic resonance angiography using belly belt.
