Synopsis

Keywords: Heart, Heart, Cine MRICine MRI derived from 3T contrast-enhanced free-running 5D whole-heart coronary MRA (free-running cine MRI) was compared with standard 2D cine MRI in 30 patients with suspected CAD. In a selected patient, temporal width was optimized to 50 ms. Then, in the remaining 29 patients, free-running cine MRI provided good agreement in LV volume and function quantification with standard 2D cine MRI with a good inter-observer reproducibility. The results suggest that free-running cine MRI allows for a shorter scan protocol by skipping the standard 2D cine MRI.
