中文摘要:
      目的 探讨MRI屏气电影成像技术评价左心室功能的价值。方法 应用屏气快速梯度回波和常规非屏气梯度回波技术对18个正常志愿者进行心脏MRI检查,并用心功能分析软件计算左室容量及心肌质量等指标。结果 ①屏气电影法与常规非屏气电影法所得结果密切相关,左室舒张末期容量(LVEDV)、左室收缩末期容量(LVESV)、左室射血分数(LVEF)、左室心肌质量的相关系数分别为0.98、0.96、0.83和0.98。②两种方法所得的各指标均值比较,差异无显著性。结论 本研究结果表明MRI屏气电影法成像时间短,无运动伪影,是一种临床评价左心功能有价值的方法。
英文摘要:
      Objective To evaluate the left ventricular function in healthy volunteers with breath-hold cine magnetic resonance imaging. Methods Eighteen healthy volunteers were scanned with breath-hold cine MR imaging sequence and conventional cine MR imaging sequence respectively then left ventricular volumes and masses were analyzed with the software of cardiac evaluation. Results ①The values of LV end-diastolic volume (LVEDV),LV end-systolic volumes (LVESV),LV ejection fraction (LVEF),and LV mass with breath-hold cine MR imaging technique were close correlated with those obtained by conventional methods(r=0.98,0.96,0.83,0.98,respectively).②There was no significant difference between the measurements of the two methods. Conclusion Breath-hold cine MR imaging is useful method for evaluation the left ventricular function because of non-ghosting artifacts and short imaging time.
