Synopsis

Keywords: Heart, Cardiovascular, coronary arteryWhole heart coronary MRA (WHCA) using fast field echo (FFE) with 3D centric ky-kz trajectory was compared with conventional FFE on healthy subjects. The mean acquisition was almost within 5 minutes using a 30-mm threshold in real-time motion correction with a navigator echoes. High resolution deep learning reconstruction (HR-DLR) was also applied to improve the image quality.
