Motion-robust myelin imaging in MRI using 1D projection gating [PDF]

Scientific Reports
Myelin-weighted imaging with inversion-recovery ultrashort-echo-time (IR-UTE) is highly motion-sensitive, yet extra hardware or longer scans are impractical.

Temporal changes in native and late gadolinium enhanced ultrashort echo time magnetic resonance imaging during gynecologic cancer radiation therapy [PDF]

Physics and Imaging in Radiation Oncology
Background and purpose: Radiotherapy (RT) response in gynecologic cancers varies widely and is influenced by several factors. We evaluated whether fibrosis detected with inversion-recovery ultrashort-echo-time (IR-UTE) MRI (magnetic-resonance-imaging ...

Conical ultrashort echo time (UTE) MRI in the evaluation of pediatric acute appendicitis. [PDF]

Abdom Radiol (NY), 2019
Magnetic resonance imaging (MRI) sequences with conical k-space trajectories are able to decrease motion artifacts while achieving ultrashort echo times (UTE). We assessed the performance of free-breathing conical UTE MRI in the evaluation of the pediatric pelvis for suspected appendicitis.Our retrospective review of 84 pediatric patients who underwent

Articular Cartilage Assessment Using Ultrashort Echo Time MRI: A Review

Frontiers in Endocrinology, 2022
Articular cartilage is a major component of the human knee joint which may be affected by a variety of degenerative mechanisms associated with joint pathologies and/or the aging process. Ultrashort echo time (UTE) sequences with a TE less than 100 µs are
