Abstract Totally Automatic Robust Quantitation in NMR (TARQUIN), a new method for the fully automatic analysis of short echo time vivo 1 H Magnetic resonance spectroscopy is presented. Analysis performed domain using non‐negative least squares, and applying soft constraints to signal amplitudes used improve fitting stability. Initial point truncation Hankel singular value decomposition water removal are reduce baseline interference. Three methods were test performance. First, metabolite...

Direct infusion nanoelectrospray Fourier transform ion cyclotron resonance mass spectrometry (DI nESI FT-ICR MS) offers high accuracy and resolution for analyzing complex metabolite mixtures. High dynamic range across a wide range, however, can only be achieved at the expense of accuracy, since large numbers ions entering ICR detector induce adverse space-charge effects. Here we report an optimized strategy wide-scan DI MS that increases but maintains accuracy. It comprises collection...

Abstract 1 H MRS has great potential for the clinical investigation of childhood brain tumours, but low incidence in, and difficulties performing trials on, children have hampered progress in this area. Most studies used a long‐ TE , thus limiting metabolite information obtained, multivariate analysis been largely unexplored. Thirty‐five with untreated cerebellar tumours (18 medulloblastomas, 12 pilocytic astrocytomas five ependymomas) were investigated using single‐voxel short‐ PRESS...

The Learning Health System (LHS) describes linking routine healthcare systems directly with both research translation and knowledge as an extension of the evidence-based medicine paradigm, taking advantage ubiquitous use electronic health record (EHR) systems. TRANSFoRm is EU FP7 project that seeks to develop infrastructure for LHS in European primary care. Methods . based on three clinical cases, a genotype-phenotype study diabetes, randomised controlled trial gastroesophageal reflux...

Brain tumours are the most common cause of cancer death in children. Molecular studies have greatly improved our understanding these but tumour metabolism is underexplored. Metabolites measured vivo been reported as prognostic biomarkers analysis surgically resected tissue allows a more extensive set metabolites to be aiding biomarker discovery and providing validation findings. In this study, were quantified across range paediatric brain using 1H-High-Resolution Magic Angle Spinning nuclear...

The aim of this study was to assess the efficacy three‐dimensional texture analysis (3D TA) conventional MR images for classification childhood brain tumours in a quantitative manner. dataset comprised pre‐contrast T 1 ‐ and 2 ‐weighted MRI series obtained from 48 children diagnosed with (medulloblastoma, pilocytic astrocytoma ependymoma). 3D 2D TA were carried out on using first‐, second‐ higher order statistical methods. Six supervised algorithms trained most influential textural features,...

Abstract To determine if apparent diffusion coefficients (ADC) can discriminate between posterior fossa brain tumours on a multicentre basis. A total of 124 paediatric patients with (including 55 Medulloblastomas, 36 Pilocytic Astrocytomas and 26 Ependymomas) were scanned using weighted imaging across 12 different hospitals 18 scanners. Apparent coefficient maps produced histogram data was extracted from tumour regions interest. Total histograms metrics (mean, variance, skew, kurtosis 10th,...

Abstract The quantitation of metabolite concentrations from in vitro NMR spectra is hampered by the sensitivity peak positions to experimental conditions. methods currently available are generally labor intensive and cannot readily be automated. Here, an algorithm presented for automatic time domain analysis high‐resolution spectra. TARQUIN uses a set basis functions obtained quantum mechanical simulation using predetermined parameters. Each function optimized subdividing it into signals...

Direct-infusion electrospray-ionization Fourier transform ion cyclotron resonance mass spectrometry (DI ESI FT-ICR MS) is increasingly being utilized in metabolomics, including the high sensitivity selected monitoring (SIM)-stitching approach. Accurate signal quantification and discrimination of real signals from noise remain major challenges for this approach, with both adversely affected by factors suppression during electrospray, ion-ion interactions detector cell, thermally-induced white...
