定量左心室（LV）功能评估与磁共振成像在20例患者中使用标准的多节段多相位稳态自由进动（SSFP）成像具有相同的空间，对比度和时间分辨率。当地机构审查委员会批准了该方案，所有患者在成像前签署了知情同意书。这项研究符合健康保险携带和责任法案。Bland-Altman分析的结果表明，两种技术产生的左心室射血分数、左心室质量和血液-肌肉对比度的估计值相似，并显示观察者间变异性最小。作者表明，与使用SSFP成像（无SENSE）进行定量LV功能评估相比，通过将SENSE与电影SSFP成像相结合，可以将采集时间缩短50%，而不会影响空间分辨率、时间分辨率或血液-肌肉对比度-噪声比。(c)RSNA，2005年。
Quantitative left ventricular (LV) function was assessed with magnetic resonance imaging in 20 patients by using standard multisection multi-phase steady-state free precession (SSFP) imaging with identical spatial, contrast and temporal resolution. The local institutional review board approved the protocol, and all patients gave signed informed consent prior to imaging. The study complied with the Health Insurance Portability and Accountability Act. Results of Bland-Altman analysis showed that both techniques produced similar estimates of LV ejection fraction, LV mass, and blood-to-muscle contrast and demonstrated minimal interobserver variability. The authors showed that it is possible, by combining SENSE with cine SSFP imaging, to reduce acquisition time by 50% without compromising spatial resolution, temporal resolution, or blood-to-muscle contrast-to-noise-ratio compared with those achieved by using SSFP imaging without SENSE for quantitative LV function assessment.
