Inverting CEST or R1ρ$$ {R}_{1\uprho} $$ data to generate solute spectra without a priori assumptions

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose The goal of CEST imaging is to reveal the underlying tissue composition and exchange. However, quantitative CEST analyses typically require strong assumptions about this same composition and exchange. The goal of this paper is to introduce a new CEST analysis (also applicable to rotating frame relaxation rate R1ρ$$ {R}_{1\uprho ...

Denoising Low‐Power CEST Imaging Using a Deep Learning Approach With a Dual‐Power Feature Preparation Strategy

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose: Low‐power (LP) chemical exchange saturation transfer (CEST) Z‐spectra have significantly reduced confounding effects and enhanced peak resolvability, thereby improving the observation and quantification of various CEST effects. However, LP Z‐spectra suffer greatly from reduced contrast‐to‐noise ratio (CNR).

Brain Pulsation Imaging Using Non‐Balanced Steady‐State Free Precession With 3D‐EPI Readout

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To present a new, fast MR imaging method for visualization and quantification of pulsatile displacement in brain tissue and fluid. Methods The natural phase‐contrast of non‐balanced steady‐state free precession combined with careful tuning of the intrinsic spoiler gradients is harnessed to measure displacement along specific physical ...

Impairments on the Construction of a Cosmic Neutrino Detector in a Romanian Salt Mine

Natural Sciences, EarlyView.
The modulus of the transfer function of an antenna when boreholed in salt. With red are represented results from the Targu Ocna salt mine and with black‐from Slanic salt mine ABSTRACT Indirect cosmic neutrino detectors utilize dense media to enhance the likelihood of neutrino interactions within the detection volume.
