Advanced Cardiac Imaging Lab

Our lab is coordinated by Dr. Jing Liu, PhD and Dr. Karen Ordovas, MD. We are focusing on pre-clinical and clinical research in advanced Cardiac MRI. We develop advanced MRI techniques for comprehensive and quantitative assessment of the heart health. Our research includes developing novel MRI data acquisition techniques and image reconstruction algorithms for 4D cardiovascular MRI, such as cardiac cine imaging, coronary imaging, perfusion imaging, velocity imaging, and tissue parametric mapping, aiming to provide images with high temporal and spatial resolution, less artifacts, and motion robustness in a short scan time.
