Comparison Between Respiratory‐Triggered and Free‐Breathing Signal Acquisition Methods for Single‐Voxel Phosphorus Magnetic Resonance Spectroscopy of the Liver on a Clinical System

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The optimal protocol for clinical liver 31P‐magnetic resonance spectroscopy (MRS) remains unclear. Single‐voxel 31P‐MRS using image‐selected in vivo spectroscopy (ISIS) employs respiratory‐triggering (RT) or free‐breathing (FB) acquisition.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

Journal of Medical Radiation Sciences, EarlyView.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

The Emergence of a Climate Change Signal in Ireland's Rainfall Extremes

International Journal of Climatology, EarlyView.
Analysis of Irish precipitation records (1930–2019) shows significant relationships between rainfall extremes and global mean surface temperature (GMST), with increases of 12%–27% per °C of warming. Emergence of unusual climate conditions is already evident at several stations, most notably in the west during winter and the southeast during summer ...

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

Journal of Raman Spectroscopy, EarlyView.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...
