'Carl-Johan Carlhäll' 'Jan Engvall' 'Tino Ebbers'] Background Quantification of the longitudinal- and transverse relaxation time in the myocardium has shown to provide important information in cardiac diagnostics. Methods for cardiac relaxation time mapping generally demand a long breath hold to measure either T1 or T2…

Quantification of the longitudinal- and transverse relaxation time in the myocardium has shown to provide important information in cardiac diagnostics. Several methods are currently available for cardiac relaxation time mapping but they generally demand a long breath hold to measure either T1 or T2 in a single 2D…

Relaxometry, specifically T_1_ and T_2_ mapping, has become an essential technique for assessing the properties of biological tissues related to various physiological and pathological conditions. Many techniques are being used to estimate T_1_ and T_2_ relaxation times, ranging from the traditional inversion or…

Purpose: To improve the accuracy of multiparametric estimation, including myelin water fraction (MWF) quantification, and reduce scan time in 3D-QALAS by optimizing sequence parameters, using a self-supervised multilayer perceptron network.Methods: We jointly optimize flip angles, T 2 preparation durations, and…

A novel method for 3D interleaved T1 and T2 mapping of the whole left ventricular myocardium within one breath hold, 3D-QALAS, has recently been developed . The method has been evaluated both in phantoms and in healthy volunteers showing a good correlation to reference relaxation time mapping methods. The aim of this…

Recently, a new method for simultaneous myocardial T1- and T2 relaxation times mapping of the whole left ventricular myocardium in a single breath hold, 3D-QALAS, has been proposed and verified in-vitro . The clinical utility of quantitative methods is dependent on a good precision to allow differentiation between…

Here we consider the q-Gaussian Tsallis functions for being applied to analyses of Surface Enhanced Raman Scattering (SERS) spectral bands, as we have previously proposed them for the deconvolution of Raman bands. The case studies here analyzed are those of L-Cysteine and Cysteamine in silver colloids, prepared with…

Despite significant potential for cyanobacteria as sustainable bioproduction chases, there are limited examples of scaled cyanobacterial bioproduction. In part, this is because most cyanobacterial species are poorly adapted to bioreactor cultivation conditions and lack features that facilitate biomass growth and…

The opportunistic pathogen Pseudomonas aeruginosa is a leading cause of airway infection in cystic fibrosis (CF) patients. P. aeruginosa employs several hierarchically arranged and interconnected quorum sensing (QS) regulatory circuits to produce a battery of virulence factors such as elastase, phenazines, and…
