Multiple‐TE Based Blood–Brain‐Barrier Water Exchange Time Measurement Using a TE‐Resolved 3D TSE Stack‐Of‐Spirals Readout

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a slice‐wise blurring‐free and densely sampled TE‐resolved multiple‐TE (mTE) ASL sequence (TASL) for measuring blood–brain barrier (BBB) water exchange time. Methods A 3D TSE spiral‐readout pCASL sequence was modified to enable TE‐resolved acquisition.

Simultaneous T2, T2*, and R2′ Mapping for Multiple Sclerosis Using Nonlinear Model‐Based Reconstruction of Undersampled Radial RARE‐EPI MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To demonstrate the synergy of undersampled radial 2in1‐RARE‐EPI acquisition and nonlinear model‐based reconstruction for accelerated and simultaneous T2, T2*, and R2′ mapping in brains of patients with multiple sclerosis (MS). Methods 2in1‐RARE‐EPI combines a RARE module with an EPI module to capture T2 and T2* information.

Ultrafast Blood T₁ Measurement Using Golden Angle Rotated Spiral k-t Sparse Parallel Imaging (GASSP): Evaluations in Both Pre- and Post-Contrast Conditions. [PDF]

Magn Reson Med
ABSTRACT Purpose Blood T1 is a key parameter for hemodynamic quantification in both non‐contrast‐ and contrast‐enhanced imaging. Individual vessel T1 has been measured using a modified Look–Locker scheme with multi‐shot EPI or FLASH in high spatial resolution, requiring ∼1 min.

Laterally Oscillating Trajectory for Undersampling Slices: LOTUS

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose While spiral sampling offers SNR advantages for diffusion MRI, its acceleration with simultaneous multislice remains relatively unexplored. This study introduces Laterally Oscillating Trajectory for Undersampling Slices (LOTUS), which is a 3D spiral‐like k‐space trajectory that aims to minimize g‐factor via controlled incoherent ...

Denoising of ASL Data Using Deep Learning Priors Generated From Distribution Remapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an effective deep learning (DL)–based method to denoise arterial spin labeling (ASL) data. Methods Conventional DL–based ASL denoising methods often suffer from overfitting and poor generalization when training data are limited.

Assessing National Sustainability Transitions in Europe: A Dynamic MCDA and Clustering‐Based Approach

Sustainable Development, EarlyView.
ABSTRACT The study evaluates the sustainable development of 42 European countries using a multi‐criteria decision analysis (MCDA) approach, based on 29 indicators covering the economic, social, and environmental pillars. All three pillars are assessed both individually and in consolidated form to provide a comprehensive view of countries ...

Epi-convergent scenario generation method for stochastic problems via sparse grid

, 2008
One central problem in solving stochastic programming problems is to generate moderate-sized scenario trees which represent well the risk faced by a decision maker. In this paper we propose an efficient scenario generation method based on sparse grid, and prove it is epi-convergent.

Beyond Growth: Governance and Education as Drivers of Environmental Health in an EKC‐Based PLS‐SEM Framework

Sustainable Development, EarlyView.
ABSTRACT Isolating environmental issues from their broader social and political context limits understanding of their true drivers. In this sense, factors such as governance and education can be powerful determinants of environmental performance. This research examines the factors influencing the Environmental Health component of the Environmental ...
