This educational talk aims to describe the basics of multidimensional imaging. The audience is expected to learn (1) what is multidimensional imaging, (2) what are the benefits and challenges of doing multidimensional imaging, (3) what are the key components in implementing multidimensional imaging, (4) how can one generate extra dimensions in cardiovascular MRI, (5) what extra dimensions can we have, and finally (6) what are current clinical applications of multidimensional imaging. Specifically, the talk will give examples of cardiovascular MRI with extra motion dimensions and/or extra contrast dimension for free-breathing comprehensive and quantitative MRI.
