Talk Title: Radial Simultaneous Multi-slice MRI for Cardiac Perfusion Assessment
Series: Medical Imaging Seminar Series
Abstract: First-pass myocardial perfusion MRI is a powerful tool to detect and evaluate coronary artery disease. In this work, we use undersampled radial simultaneous multi-slice (SMS) acquisitions to achieve greater slice coverage and reduced sensitivity to motion, compared to current standard techniques. I will present two acquisition frameworks for myocardial perfusion. One that uses radial SMS and a pixel-tracking method to produce multi-view perfusion images. The other framework uses continuous acquisition without gating or magnetization preparation. This work employed patch-based locally low-rank constraints and temporal total variation constraints.
Biography: Ye Tian recently completed his Ph.D. at the University of Utah (2014 -“ 2019). He has been working in the cardiovascular MRI group of Utah Center of Advanced Imaging Researches (UCAIR) since May 2016 under the guidance of Edward DiBella and Ganesh Adluru. His interests include myocardial perfusion DCE-MRI, radial SMS, image reconstruction, fast imaging, and myocardial T1 mapping.
