Overview
After a review of physics and clinical utilization of MRI for Musculoskeletal imaging, special challenges of imaging children or adolescents, as well as patients with implanted metal hardware, are described. The course will then discuss advanced musculoskeletal imaging methods, and imaging from low to high field.

Target Audience
This course is designed to bring together both radiologists and MRI physicists working in MRK areas to review both problems and solutions across the range of tissues and joints.

Educational Objectives
As a result of attending this course, participants should be able to:
-Summarize both the physics and clinical questions in MSK imaging
-Identify challenges and solutions for imaging young people and patients with metal.
-Explain implications of advanced techniquest and both low-field and high-field imaging applied to musculoskeletal imaging.

07:45		Overview of MSK MRI Physics View Presentation Video L. Tugan Muftuler
08:15		Pediatric and Adolescent MSK Radiology View Presentation Video Jie Nguyen Keywords: Musculoskeletal: Cartilage, Cross-organ: Pediatric, Image acquisition: Sequences MRI is routinely utilized to complement the clinical assessment of children with a diversity of musculoskeletal pathologies. Current session will highlight 2 major hot topics in pediatric musculoskeletal radiology: (a) radiation-free bone imaging, and (b) maturation-dependent microstructural changes that should not be mistaken for pathology. For radiation-free bone imaging, current application, potential future uses, and limitations of ultrashort TE (UTE) and zero TE (ZTE) in children will be discussed. For maturation-dependent microstructural changes, use of T2-relaxation mapping (T2-mapping) of cartilage and diffusion tensor imaging (DTI) of the growth plates will be reviewed.

10:15		Advanced Musculoskeletal MRI View Presentation Video Jeongah Ryu Keywords: Musculoskeletal: Cartilage In the last decade musculoskeletal MRI has unprecedented advances. With 3 Tesla field strength high performance gradients and rapid radiofrequency pulse transmission, advanced multichannel receiver coil and surface coil technologies, quantitative MRI techniques and radiomics, MR fingerprinting, synthetic contrast generation, parallel imaging, compressed sensing, simultaneous multislice acquisition techniques have been developed. Deep learning and artificial intelligence algorithms can enhance MRI with unparalleled gains in image speed and quality without signal-to-noise loss. These advances brought challenges too. In this educational lecture we will look around these issues centering around the fundamentals including definitions, advantages, and clinical applications.
10:45		Low-Field Musculoskeletal MRI View Presentation Video Jan Vosshenrich Keywords: Musculoskeletal: Skeletal, Musculoskeletal: Joints, Physics & Engineering: Low-Field MRI Although the vast majority of musculoskeletal MRI examinations is performed at 1.5 and 3.0T, low-field MRI currently experience a renaissance and offers new opportunities for affordable imaging given lower installation and operational cost. Despite inherently lower signal-to-noise ratios, developments in coil design and image reconstruction techniques improve signal yield and allow to assess musculoskeletal pathologies with high diagnostic confidence. Additionally, imaging of patients with high-susceptibility metallic implants benefits from lower field strengths in terms of reduced metal artifacts. This lecture reviews the technical and economic aspects of low-field musculoskeletal MRI and discusses its applications, challenges and opportunities.
11:15		Ultra-High-Field Musculoskeletal MRI View Presentation Video Stefan Zbyn Keywords: Musculoskeletal: Joints, Physics & Engineering: High-Field MRI MRI at ultra-high-field (7T and above) offers unique opportunities for improved resolution, contrast, and more accurate biochemical characterization of Musculoskeletal tissues compared to lower field strengths. While some challenges remain to be addressed for more impactful clinical workflows, recent hardware and software developments, as well as advancements in morphological and quantitative MRI techniques for ultra-high-field MR systems have great potential to further increase the relevance of 7T MRI in clinical musculoskeletal research and advance the translation of 7T MRI to clinical arena.
