AI Article Synopsis
- The study assessed the accuracy and consistency of T1, T2*, and proton density values from quantitative parameter mapping (QPM) using the ISMRM/NIST MRI system phantom and compared findings with computer simulations.
- Researchers compared QPM-derived relaxation times and proton density against reference values from the phantom and traditional methods to validate their results.
- The results indicated a strong correlation between QPM values and reference measurements, with simulations aligning closely with actual scan variations, suggesting minimal influence from factors other than noise.
Article Abstract
We aimed to evaluate the accuracy and repeatability of the T1, T2*, and proton density (PD) values obtained by quantitative parameter mapping (QPM) using the ISMRM/NIST MRI system phantom and compared them with computer simulations. We compared the relaxation times and PD obtained through QPM with the reference values of the ISMRM/NIST MRI system phantom and conventional methods. Furthermore, we evaluated the presence or absence of influences other than noise in T1 and T2* values obtained by QPM by comparing the obtained coefficient of variation (CV) with simulation results. The T1, T2*, and PD values by QPM showed a strong correlation with the measured values and the referenced values. The simulated CVs of QPM calculated for each sphere showed similar trends to those of the actual scans.

Phase change materials such as Ge2Sb2Te5 (GST) are ideal candidates for next-generation, non-volatile, solid-state memory due to the ability to retain binary data in the amorphous and crystal phases and rapidly transition between these phases to write/erase information. Thus, there is wide interest in using molecular modeling to study GST. Recently, a Gaussian Approximation Potential (GAP) was trained for GST to reproduce Density Functional Theory (DFT) energies and forces at a fraction of the computational cost [Zhou et al.

Accurate and rapid diagnosis of traumatic brain injury (TBI) is essential for high-quality medical services. Nonetheless, the current diagnostic platform still has challenges in rapidly and accurately analysing clinical samples. Here, we prepared a highly stable, repeatable and sensitive gold-plated silver core-shell nanowire (Ag@AuNWs) for surface-enhanced Raman spectroscopy (SERS) metabolic fingerprint diagnosis of TBI.

The study aimed to determine whether the implementation of HIRAID improved the accuracy of nurses' documentation across a large rural health district.
Methods: A Quasi-experimental pre-post study design was conducted across 10 rural emergency departments between November 2020 and November 2021, with HIRAID implemented in February 2021.
