Automated Coregistered Segmentation for Volumetric Analysis of Multiparametric Renal MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aims to develop and evaluate a fully automated deep learning‐driven postprocessing pipeline for multiparametric renal MRI, enabling accurate kidney alignment, segmentation, and quantitative feature extraction within a single efficient workflow. Methods Our method has three main stages.

Quantitative Diffusion and T2 Mapping Using RF‐Modulated Phase‐Based Gradient Echo Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce and evaluate the feasibility of a novel RF‐phase modulated gradient echo (GRE) method for quantitative diffusion MRI, aimed at mitigating geometric distortion and enabling high‐resolution 3D quantitative diffusion/T2 mapping as a complementary alternative to conventional DWI.

Clinically Feasible White Matter Fiber Tractography in Peritumoral Zones With Cerebral Vasogenic Edema

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In diffusion MRI, vasogenic edema manifests as a major fraction of isotropic water that dilutes the anisotropic intra‐axonal portion of the signal. Many tractography algorithms mistake vasogenic edema for the white matter boundary and terminate tracking to prevent producing spurious streamlines.

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Strong-Gradient Diffusion-Weighted Imaging of Prostate Cancer Using an Inside-Out Nonlinear Gradient Coil. [PDF]

Magn Reson Med
ABSTRACT Purpose To demonstrate improved image quality and lesion conspicuity in prostate diffusion‐weighted imaging (DWI) using an inside‐out nonlinear gradient coil that provides locally strong gradients (200–500 500 mT/m) at typical prostate positions.

Semi‐Automatic Assessment of Crohn's Disease Activity by Combined Analysis of Bowel Lesions and Creeping Fat

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate Crohn‐BOOST, an open‐source tool enabling semi‐automatic segmentation of intestinal lesions and creeping fat on magnetic resonance enterography (MR Enterography), and to assess whether quantitative metrics derived from these segmentations relate to radiological disease activity scored with simplified MaRIA ...

MRI‐based qualitative, quantitative, and radiomics/deep learning methods for assessing treatment response after neoadjuvant chemoradiotherapy in patients with locally advanced rectal cancer

Precision Radiation Oncology, EarlyView.
MRI, owing to its superior soft tissue contrast and spatial resolution, has become the preferred noninvasive modality for assessing nCRT efficacy. This review synthesizes current evidence on MRI‐based assessment of nCRT efficacy in LARC and discusses future directions.

Leveraging Life Cycle Assessment for Informing Packaging Eco‐Design and Eco‐Modulation

Sustainable Development, EarlyView.
ABSTRACT Eco‐modulation is designed to promote the adoption of eco‐design. However, in practice, its application is mostly concentrated on end‐of‐life (EoL) optimization. This study addresses the gap by proposing a framework to assess product–packaging systems as integrated units throughout the full life cycle.
