Ultrashort Echo-Time MR Imaging of the Pediatric Head and Neck

Magnetic Resonance Imaging Clinics of North America, 2021
Bone MR imaging techniques use extremely rapid echo times to maximize detection of short-T2 tissues with low water concentrations. The major approaches used in clinical practice are ultrashort echo-time and zero echo-time. Synthetic CT generation is feasible using atlas-based, voxel-based, and deep learning approaches.

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.

Ultrashort echo time (UTE) MRI of the spine in thalassaemia

The British Journal of Radiology, 2004
Back pain is common in adult patients with homozygous thalassaemia, and degenerative disc disease is increasingly recognised as a cause. Ultrashort echo time (UTE) pulse sequences, which are sensitive to the presence of short T(2) relaxation components in tissue produced by iron deposition and other processes, were used to examine the lower thoracic ...

Functional magnetic resonance imaging with an ultrashort echo time.

Medical physics, 2013
The purpose of the authors study was to investigate a functional MRI (fMRI) technique with an ultrashort echo-time (UTE) sequence.An UTE-based fMRI technique was applied to 17 young healthy volunteers during visual stimulations on a 3T MRI system. In addition, a blood oxygen level-dependent (BOLD) fMRI image was also obtained to compare functional ...

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.
