Deep Learning Improves Robustness of Voxelwise Kinetic Modeling for Hyperpolarized Carbon‐13 MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate whether deep learning improves the robustness of voxelwise kinetic parameter estimation from hyperpolarized (HP) 13C MRI compared with nonlinear least‐squares (NLLS) fitting. Methods A hybrid neural network (NN) was trained on synthetic pyruvate/lactate time courses generated from an open‐system two‐compartment HP 13C ...

Free‐Breathing Hepatic Oxygen Extraction Fraction (OEF) Mapping Using Radial GESSE

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Noninvasive assessment of hepatic oxygenation is relevant for evaluating liver both in acute and long‐term liver pathologies. However, existing methods are limited to single‐slice acquisitions and require breath‐holding. This study aims to develop and evaluate a motion‐robust technique for whole‐liver oxygen extraction fraction (OEF ...

Evaluation of 7 Tesla pTx Body Coils Regarding Transmit and Receive Performance

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Most sites develop and use custom coils for 7 T body MRI since no standard pTx body coil exists, leading to diverse coil designs differing in transmit element type, layout, and number of receive channels. This study investigates and compares eight existing coils, including one remote body coil array and seven local arrays, regarding ...

Curating landscapes to encourage care for biodiversity through arts and citizen science

open access: yesPeople and Nature, EarlyView.
Abstract This study investigates how combining Citizen Science and Art workshops within curated wildflower meadows can generate repeated, positive experiences with nature, and foster a sense of care for it. The project aimed to increase awareness, encourage responsibility, and develop competencies related to urban nature.
