This education course is designed for radiologists and physicists to learn about state-of-the-art in UTE and ZTE imaging and its clinical applications. Technical concepts underpinning UTE and ZTE sequences will be covered from basic to advanced levels and clinical applications will be featured.

Target Audience
Radiologists and Physicists

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

-Recognize the potential applications and current limitations of ultra-short TE imaging techniques;
-Identify areas of active research in UTE imaging; and
-Describe applications of UTE imaging to musculoskeletal applications.

UTE & ZTE Imaging Techniques
Florian Wiesinger
Ultra-short TE (UTE) and Zero TE (ZTE) MR pulse sequences provide unique capabilities for imaging short-lived tissues (i.e. T2 < 1ms) which are otherwise invisible using conventional MR imaging with echo times (TE) in the milliseconds range. The presentation will first review 2D and 3D UTE imaging using center-out (typically radial) k-space sampling. Subsequently, ZTE imaging will be described highlighting its unique features regarding RF excitation and silent imaging. At the end of the presentation related methods like SWIFT and Looping Star will be briefly mentioned as well.

Clinical Applications of UTE/ZTE
Richard Hodgson
UTE imaging techniques, including quantitative measurements such as T2* and off resonance saturation ratios, are increasingly being investigated in patients with musculoskeletal diseases which involve tissues that are difficult to assess with conventional MRI. Diseases that have been assessed using UTE imaging include Achilles tendinopathy, articular cartilage and meniscal injury in the knee and degenerative disc disease in the spine. UTE imaging estimates of cortical bone pore water are being validated with the aim of improving fracture risk assessment.
