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

Three-dimensional ultrashort echo time magnetic resonance imaging in pediatric patients with pneumonia: a comparative study [PDF]

BMC Medical Imaging, 2023
Background UTE has been used to depict lung parenchyma. However, the insufficient discussion of its performance in pediatric pneumonia compared with conventional sequences is a gap in the existing literature.

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 ...

Brain short T2 component imaging using double adiabatic inversion recovery prepared ultrashort Echo time (DIR-UTE) sequence [PDF]

NeuroImage
Short T2 components in the brain are uniquely associated with myelin structure, but direct MR imaging is challenging due to their relatively short T2 values and low proton density compared to long T2 water.

Ultrashort Echo Time Magnetic Resonance Morphology of Discovertebral Junction in Chronic Low Back Pain Subjects [PDF]

Tomography
Background: Chronic low back pain (LBP) has been associated with intervertebral disc (IVD) degeneration, but its association with abnormal morphology at the discovertebral junction (DVJ) is unclear.
