Overview
This course offers a broad overview of past, present, and future MRI techniques for musculoskeletal (MSK) diseases. The session will review past and current MSK MR imaging techniques and pulse sequences, impacting daily clinical practices. The session will also include developing and novel MR techniques applied to MSK diseases such as quantitative MRI, ultra-high field MRI, and artificial intelligence (AI) algorithms.

Target Audience
Radiologists, clinicians, technologists, and scientists interested in learning about past, present, and future advanced musculoskeletal imaging techniques.

Educational Objectives
As a result of attending this course, participants should be able to:
- Explain past and present clinical MRI applications for MSK diseases;
- Describe advanced musculoskeletal imaging techniques; and
- Discuss future, novel, and advanced imaging techniques applied to diagnosing MSK diseases.

		The Latest & Greatest: Past & Present Watch the Video Jutta Ellermann Ultrahigh Field (UHF) human MRI has a history of more than 30 years of technology development enabling the introduction of the first clinical 7T MRI, which was FDA approved in 2017. Currently approved MSK applications are limited to the knee, where improved SNR with higher resolution and contrast can make a clinical difference. However, to develop UHF MRI for a wide range of clinical MSK applications to its full potential, introduction of Parallel Transmit Technology (PTx) is needed to overcome current limitations. Beyond 7T there are exciting possibilities for human MSK-research at 10.5T, such as Na+ MRI for cartilage.
		The Latest & Greatest: Future Watch the Video Xiaojuan Li The current trend of MSK imaging is from qualitative imaging to quantitative imaging, and from imaging that provides anatomy only to imaging that provide compositional, biochemical, metabolic and functional information. In this talk, we will use quantitative MRI in osteoarthritis as an example to discuss this exciting trend. Quantitative MRI standardization and acceleration, as well as automated image analysis will significantly enhance researchers’ ability to apply such techniques to large scale data and will greatly facilitate their clinical translation. Lastly, a few examples on advanced MRI in MSK applications, including UTE/ZTE, DTI, CEST and 7T MRI will be demonstrated.
