Ultrashort echo time imaging with bicomponent analysis

Magnetic Resonance in Medicine, 2011
AbstractBiological tissues frequently contain different water compartments, and these often have distinct transverse relaxation times. Quantification of these may be problematic on clinical scanners because spin echo sequences usually have initial echo times that are too long to accurately quantify shorter relaxation time components.

Quantitative Ultrashort Echo Time (UTE) imaging of Osteochondral Junction

ISMRM Annual Meeting, 2023
MRI-based compositional imaging of cartilage has higher sensitivity to detect early changes in osteoarthritis. The osteochondral junction (OCJ) is of particular interest since it has been associated with early changes and progression of cartilage degeneration.

Two-dimensional ultrashort echo time imaging using a spiral trajectory

Magnetic Resonance Imaging, 2008
Tissues with very short transverse relaxation time (T2) cannot be detected using conventional magnetic resonance (MR) sequences due to the rapid decay of excited MR signals. In this work, a multiecho sequence employing half-pulse excitation and spiral sampling was developed for ultrashort echo time (UTE) imaging of tissues with short T2. Spiral readout
