What is it about?

Ultrashort Echo Time (UTE) pulse sequences allow direct magnetic resonance imaging (MRI) of species with short transverse relaxation times, such as bone, menisci, ligaments, tendons, lung, iron overload, and myelin, which are "invisible" with conventional MRI techniques. A systematic review of UTE MRI techniques is provided on creating high-contrast images of short-T2 species and measuring properties that are important to diagnosing and characterizing disease states.

Why is it important?

The short-T2 species play critical roles in the body's normal function. UTE imaging of both conventional MRI “visible” long-T2 species and “invisible” short-T2 species will likely improve the classification and staging of diseases in a significant way.


We will continue to develop more robust and faster UTE MRI techniques for morphological and quantitative assessment of various short-T2 species in the body. Direct imaging of short-T2 species can be used to improve the diagnosis of various diseases in the body's musculoskeletal, nervous, respiratory, gastrointestinal, and cardiovascular systems.
