Magnetic resonance ultrashort echo time spin-echo imaging of the deepest layers of articular cartilage [PDF]

Science China Life Sciences, 2013
L'imagerie par résonance magnétique (IRM) est apparue comme une technique radiologique invasive permettant d'évaluer et de caractériser les lésions du cartilage dans le cadre d'une lésion et d'une maladie articulaire dégénérative. Cependant, la plupart des techniques d'IRM cliniques et de recherche actuellement disponibles, y compris l'écho de spin ...

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

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.

Outracing Lung Signal Decay – Potential of Ultrashort Echo Time MRI [PDF]

RöFo - Fortschritte auf dem Gebiet der Röntgenstrahlen und der bildgebenden Verfahren, 2018
Background Magnetic resonance imaging (MRI) of the pulmonary parenchyma is generally hampered by multiple challenges related to patient respiratory- and circulation-related motion, low proton density and extremely fast signal decay due to the structure of the lungs evolved for gas exchange.

On‐Water Surface Synthesis of 2D Conjugated Metal–Organic Framework Films With Controllable Layer Orientation Enabling High‐Performance Chemiresistive Sensing

Advanced Materials, EarlyView.
Layer orientation dictates charge transport in 2D conjugated metal–organic frameworks, yet controllable methods remain scarce. We report surfactant monolayer‐assisted on‐water synthesis of cm2‐scale Ni‐HHTP films with programmable face‐on and edge‐on orientations.

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

Advanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Molecular alignment echoes probing collision-induced rotational-speed changes

Physical Review Research, 2020
We show that the decays with pressure of the rotational alignment echoes induced in N_{2}O-He gas mixtures by two ultrashort laser pulses with various delays show detailed information about collision-induced changes of the rotational speed of the ...
