The utilization of magnetic resonance imaging (MRI) in radiotherapy (RT) has gained tremendous research and clinical interests in multiple applications, such as MRI only simulation and treatment planning, on-board MRI-guided adaptive RT, and longitudinal functional MRI for treatment response estimation and prediction. Besides the superior soft tissue contrast, one unique feature about MRI is that it is very versatile. By modifying MR pulse sequences, one can acquire not only high quality anatomical images but also functional and quantitative information, e.g. diffusion weighted MRI (DWI), perfusion MRI, T1 mapping, T2 mapping, etc. This versatility of MRI leads to great potentials that motivate continued advances in MRI technologies for probing and understanding the underlining tissue physiology and biology. Some of the technologies are developed specifically with the goal of better RT implementation. In this course, physicists who have been working on novel MR technical developments in the diagnostic imaging field and RT field are invited to share their knowledge on this topic. The following will be covered: 1) Recent advances in diffusion weighted MRI and perfusion MRI; 2) Tissue microenvironment MRI including MR spectroscopic imaging and Chemical Exchange Saturation Transfer (CEST) MRI, etc.; 3) Multi-parametric quantitative MRI. 4) New technologies for motion robustness in quantitative MRI, an important requirement for reliable clinical implementation. The course should provide a clear yet comprehensive review of the recent emerging MR technical developments on functional and quantitative MRI, with a focus on their RT applications.

Learning Objectives:
1. Understand the concepts of several widely studied functional and quantitative MRI technologies
2. Review recent advances in technological development and clinical applications using these techniques
3. Learn the challenges of implementing these techniques in RT and the recent advances in addressing one of the main challenge: motion.
