Image‐Derived Volumetry During Forced Expiration Using a 3D Fermat Looped, Orthogonally Encoded Trajectory

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable MRI‐based nongated 3D depiction of forced expiration with both high spatio‐temporal resolution and fidelity of lung dynamics. Methods An undersampled 3D Fermat looped, orthogonally encoded trajectory (FLORET) was optimized for nonsegmented dynamic acquisitions during forced expiration and a corresponding model‐based ...

Motion‐Robust Approach for 4D Cardiac Cine Using 2D Real‐Time Acquisitions and Slice‐to‐Volume Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 4D cardiac cine is a powerful tool for comprehensive cardiac function assessment; however, current methods rely on regular breathing and are sensitive to bulk motion and arrhythmia. We aim to develop a 4D cardiac cine approach that requires no patient cooperation and is robust to irregular breathing, bulk motion, and cardiac arrhythmia.

Strain Rate Angle Distribution as an Indicator of Post‐Infarct Myocardial Remodeling: Proof‐of‐Concept of a Novel Application of the MRI Derived Strain Rate Tensor Field

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Left ventricular (LV) strain is an early indicator of myocardial dysfunction. However, conventional strain metrics do not fully account for the multidirectional nature of myocardial deformation. The strain rate tensor, derived from velocity‐encoded MRI, represents the time‐resolved magnitude and direction of strain rate without the ...

The Technology Dependence Index (TDI): Development and Validation in Neonatal and Pediatric Populations

Research in Nursing &Health, EarlyView.
ABSTRACT The survival of infants and children with complex medical conditions continues to increase, underscoring the need to quantify technology dependence more effectively. Existing measures emphasize mortality risk and fail to capture the burden of ongoing technological support.

Applications and prospects of artificial intelligence and digital medicine in pediatric nasal skull base tumors

Pediatric Investigation, EarlyView.
Pediatric nasal skull base tumors present diagnostic and therapeutic challenges due to their deep location, nonspecific symptoms, and the narrow nasal cavity in children. Although artificial intelligence (AI) and digital medicine have advanced early diagnosis, multidisciplinary treatment, and prognosis, their application in these rare tumors remains ...

Performance evaluation of thick carbon fiber‐reinforced laminates manufactured using six‐magnetron microwave system

Polymer International, EarlyView.
IM7/Cycom 5320‐1 unidirectional prepreg has been used to fabricate 64‐layer laminated composites. A custom‐built six‐magnetron microwave applicator and an autoclave were employed to manufacture the composite panels. Mechanical performance of the microwave‐cured composites has been juxtaposed to autoclave‐cured composites in terms of uniaxial tensile ...
