Overview
The course will provide an in-depth discussion of state-of-the-art imaging techniques used musculoskeletal imaging from both technical and clinical perspectives. Imaging around metal, acceleration methods, diffusion imaging, multiparametric mapping, and spectroscopy will be reviewed. Each topic will contain a lecture focused on technical review as well as a lecture demonstrating clinical application.

Target Audience
Radiologists, Physicists and Clinical Care providers interested in reviewing current MR imaging techniques and their diagnostic applications.

Educational Objectives
Upon completion of this course, participants should be able to:

-Recognize the importance of imaging around metal and need for acceleration techniques;
-Apply and interpret diffusion imaging and multiparametric mapping in the clinical setting; and
-Integrate proton MR spectroscopy for the characterization of tumors and tissues.

08:15	MR Imaging Around Metal: Technical Aspects Clemens Bos Orthopedic implants cause significant artifact in MRI. Here, we will make a classification of these artifacts. Then approaches to minimize the susceptibility related artifacts are desciribed, such as the use of "wide band" sequences, view angle tilting and multi-spectral imaging methods.
08:50	MR Imaging Around Metal: Clinical Applications Kathryn Stevens Metal implants are now commonplace in modern medicine. MRI evaluation of symptomatic patients with orthopedic hardware used to be severely limited by susceptibility artifact. However, recent advances in metal suppression techniques allow improved imaging around metal, making MRI effective for evaluation of patients with symptomatic implants, even at higher magnetic field strengths. This lecture will cover some of the common clinical applications of metal suppression MRI, particularly with respect to total hip and knee arthroplasties, and will also demonstrate the utility of metal suppression with respect to other implants and in the evaluation of patients with spinal hardware.
09:25	Acceleration Methods: Technical Aspects Leslie Ying, Xiaojuan Li MR quantitative imaging have been shown to be promising markers for detecting early degeneration and predicting disease progression in musculoskeletal (MSK) imaging due to its relatively independence of scanners/protocols. However, the long acquisition time and associated low resolution quantitative imaging have impeded their wide applications in clinical trials and practice. Recently compressed sensing and parallel imaging based acceleration methods have shown promise to address these challenges such that the quantitative imaging can be translated into clinical practice. Despite the extensive studies in other applications such as brain imaging, MR quantitative imaging in MSK has been overlooked. This course will teach some acceleration methods combining compressed sensing and parallel imaging and show their applications in MSK imaging.
10:00	Acceleration Methods: Clinical Applications Richard Kijowski Multiple different methods are now available which can been used to accelerate musculoskeletal MRI and improve the efficiency of MRI protocols for evaluating musculoskeletal diseases without compromising image quality or diagnostic performance. These methods including the use of highly efficient spiral and radial k-space trajectories, 3T scanners, parallel imaging acceleration, isotropic resolution imaging, compressed sensing k-space under-sampling, and T2 shuffling.

11:05	MSK Applications of Diffusion Weighted Imaging: Technical Aspects Jose Raya The objective of this talk is to present a hands-on on the acquisition and processing of diffusion-weighted imaging tailored to MSK applications. In this presentation we will explain how diffusion is measured and which is the meaning of the experimental parameters; discuss the different acquisition strategies for diffusion-weighted imaging; and learn how to optimize a diffusion protocol for a given
