Bi-Exponential 3D UTE-T1ρ Relaxation Mapping of Ex Vivo Human Knee Patellar Tendon at 3T

open access: yesBioengineering
Introduction: The objective of this study was to assess the bi-exponential relaxation times and fractions of the short and long components of the human patellar tendon ex vivo using three-dimensional ultrashort echo time T1ρ (3D UTE-T1ρ) imaging ...

Quantitative ultrashort echo time magnetization transfer (UTE-MT) for diagnosis of early cartilage degeneration: comparison with UTE-T2* and T2 mapping

open access: yesQuantitative Imaging in Medicine and Surgery, 2020
To investigate the feasibility of using quantitative ultrashort echo time magnetization transfer (UTE-MT) technique in diagnosing early cartilage degeneration and to compare the technique's diagnostic efficacy with UTE-T2* mapping and T2 mapping.Twenty human anterolateral condyle specimens with degeneration were obtained from volunteers undergoing ...

Free‐breathing 3D pulmonary ventilation mapping at 0.55 T using stack‐of‐spiral out‐in bSSFP

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 1, Page 430-441, January 2026.
Abstract Purpose To develop a free‐breathing pulmonary imaging technique that provides three‐dimensional (3D) structural images and regional ventilation maps, and to evaluate its repeatability and accuracy compared with two‐dimensional phase‐resolved functional lung (PREFUL) and global tidal volume.

Structure-function relationships at the human spinal disc-vertebra interface. [PDF]

open access: yes, 2018
Damage at the intervertebral disc-vertebra interface associates with back pain and disc herniation. However, the structural and biomechanical properties of the disc-vertebra interface remain underexplored.

Mn2+ Complex of a Fluorinated CDTA‐Derivative: Stability, Inertness, and Paramagnetic 1H, 17O, and 19F Relaxation Properties

open access: yesChemistry – A European Journal, Volume 31, Issue 71, December 17, 2025.
The fluorinated CDTA‐bisamide derivative ligand, L2, forms a stable and highly inert complex with Mn2+. MnL2 has one inner sphere water coordinated to the central metal ion, hence good proton relaxivity, and the paramagnetic metal ion induces important acceleration of 19F relaxation, provides good signal‐to‐noise ratios on 19F phantom UTE MR images ...

Are Collagen Protons Visible with the Zero Echo Time (ZTE) Magnetic Resonance Imaging Sequence: A D2O Exchange and Freeze-Drying Study

open access: yesBioengineering
It is known that ultrashort echo time (UTE) magnetic resonance imaging (MRI) sequences can detect signals from water protons but not collagen protons in short T2 species such as cortical bone and tendons.

Cardiac 4D phase-contrast CMR at 9.4 T using self-gated ultra-short echo time (UTE) imaging

open access: yesJournal of Cardiovascular Magnetic Resonance, 2017
Background Time resolved 4D phase contrast (PC) cardiovascular magnetic resonance (CMR) in mice is challenging due to long scan times, small animal ECG-gating and the rapid blood flow and cardiac motion of small rodents.

Cardiac-respiratory self-gated cine ultra-short echo time (UTE) cardiovascular magnetic resonance for assessment of functional cardiac parameters at high magnetic fields

open access: yes, 2014
Background: To overcome flow and electrocardiogram-trigger artifacts in cardiovascular magnetic resonance (CMR), we have implemented a cardiac and respiratory self-gated cine ultra-short echo time (UTE) sequence.
