Synopsis

Learn about how the physical properties at low field (<1T) can provide opportunities for novel cardiovascular and pulmonary imaging applications. In addition, we will discuss what imaging paradigms do and don’t work at low fields, and current research exploring low field cardiothoracic imaging.

Syllabus

Low field (<1T) MR imaging may enable accessible healthcare through reduced system costs, and this topic has been of recent research interest in the community [1-4].
In this talk, attendees will learn about how the physical properties at low field can provide opportunities for novel cardiovascular and pulmonary imaging applications. In addition, attendees will learn about what structural and quantitative imaging paradigms do and don’t work at low fields, and current research exploring low field cardiothoracic imaging.
