Abstract: In recent years, Cardiovascular Magnetic Resonance Imaging has played an increasingly important role in assessing the heart in fetal and pediatric patients, providing a comprehensive 3D assessment of anatomy, function, and blood flow. In general, MRI requires careful compensation of both cardiac and respiratory motion in order to ensure high quality images that are not degraded by artifact. However, in fetal and pediatric imaging the likelihood of bulk patient movement provides an additional confounding factor that may either preclude scanning altogether or require sedation. In this talk, I will provide an overview of techniques we have developed for high resolution dynamic cardiac imaging in the presence of patient movement. With these methods we aim to improve the ease-of-use of Cardiovascular MRI and work towards decreasing the need for sedation in pediatric patients while also exploring new avenues for imaging the fetus.
About the Speaker: Christopher Roy graduated with an honors in physics BSc degree from Mount Allison University, in Canada, in 2010. He completed his MSc in 2012 and PhD in 2017, both in Medical Biophysics at the University of Toronto. Working with Drs. Christopher Macgowan and Mike Seed at the Hospital for Sick Children in Toronto, Chris’ graduate research focused on accelerated imaging and motion correction strategies for MRI of the fetal heart. This work led to the first retrospectively gated fetal CINE bSSFP images and first application of compressed sensing to dynamic fetal imaging. Chris has a strong interest in using post-processing methods to address practical challenges in clinical applications. Chris is currently a lecturer (maître-assistant) at the Department of Radiology, Lausanne University Hospital (CHUV) and University of Lausanne (UNIL) and is leading a Swiss National Science Foundation Ambizione funded project developing multi-dimensional imaging techniques targeting the fetal and pediatric heart, hosted in CIBM MRI CHUV -UNIL Translational MR Imaging Section.
The monthly meet-up seminar series is a great environment to ask questions or to share insights on challenges and solutions. It’s also a good way to broaden and enrich professional networks.
