Ultrashort time-to-echo MRI of the cartilagenous endplate and relationship to degenerative disc disease and schmorl's nodes [PDF]

, 2011
Session - The Short of ItINTRODUCTION: The vertebral endplate is composed of an inner bony and outer cartilaginous endplates (CEP). The CEP supplies the intervertebral disc (IVD) with nutrients and metabolites, and is instrumental for metabolism ...

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

Magnetic 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.

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

Chemistry – 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 ...

Ferrimagnetic Vortex Nanorings Facilitate Efficient and Safe Deep‐Brain Magnetothermal Stimulation in Freely Moving Mice

Exploration, Volume 5, Issue 6, December 2025.
Magnetothermal neuromodulation is greatly hindered by its long stimulus‐response time and high safety risks due to the poor heat‐generating performance of the nanomediators. We report the establishment of a novel ferrimagnetic vortex iron oxide nanoring (FVIO)‐mediated efficient and safe magnetothermal neurostimulation.

Magnetic Resonance Imaging in the Clinical Evaluation of Lung Disorders: Current Status and Future Prospects

Journal of Magnetic Resonance Imaging, Volume 62, Issue 5, Page 1260-1279, November 2025.
ABSTRACT The low proton density and high signal decay rate of pulmonary tissue have previously hampered the application of magnetic resonance imaging (MRI) in the clinical evaluation of lung disorders. With the continuing technical advances in scanners, coils, pulse sequences, and image postprocessing, pulmonary MRI can provide structural and ...

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

, 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.
