Wyke Huizinga,Dirk H. J. Poot,Dirk H. J. Poot,Jean-Marie Guyader,Remy Klaassen,Bram F. Coolen,M. van Kranenburg,R.J. Van Geuns,André Uitterdijk,Mathias Polfliet,Mathias Polfliet,Jef Vandemeulebroucke,Jef Vandemeulebroucke,Alexander Leemans,Wiro J. Niessen,Wiro J. Niessen,Stefan Klein +16 more
TL;DR: The groupwise registration method with a similarity measure based on PCA is the preferred technique for compensating misalignments in qMRI.
Journal ArticleDOI
Effects of caffeine and maltodextrin mouth rinsing on P300, brain imaging and cognitive performance
K De Pauw,Bart Roelands,Kristel Knaepen,Mathias Polfliet,Johan Stiens,Romain Meeusen,Romain Meeusen +6 more
TL;DR: Only CAF MR exerted a likely beneficial effect on reaction time due to the subsequent activation of both the orbitofrontal and dorsolateral prefrontal cortexes.
Journal ArticleDOI
Intrasubject multimodal groupwise registration with the conditional template entropy.
Mathias Polfliet,Mathias Polfliet,Mathias Polfliet,Stefan Klein,Wyke Huizinga,Margarethus M. Paulides,Wiro J. Niessen,Jef Vandemeulebroucke +7 more
TL;DR: A novel similarity metric for multimodal groupwise registration is proposed that calculates the sum of the conditional entropy between each image in the group and a representative template image constructed iteratively using principal component analysis.
Journal ArticleDOI
Registration strategies for multi‐modal whole‐body MRI mosaicing
Jakub Ceranka,Jakub Ceranka,Mathias Polfliet,Mathias Polfliet,Mathias Polfliet,Frédéric Lecouvet,Nicolas Michoux,Johan De Mey,Jef Vandemeulebroucke,Jef Vandemeulebroucke +9 more
TL;DR: To test and compare different registration approaches for performing whole‐body diffusion‐weighted (wbDWI) image station mosaicing, and its alignment to corresponding anatomical T1 whole‐ body image.
Journal ArticleDOI
Ventilation heterogeneity in smokers: role of unequal lung expansion and peripheral lung structure
Sylvia Verbanck,Mathias Polfliet,Mathias Polfliet,Mathias Polfliet,Daniel Schuermans,Bart Ilsen,Johan De Mey,Eef Vanderhelst,Jef Vandemeulebroucke,Jef Vandemeulebroucke +9 more
TL;DR: Smoking-induced ventilation heterogeneity measured at the mouth via established washout indices (lung clearance index LCI and alveolar mixing efficiency AME) potentially results from unequal expansion, which can be quantified by CT, and structural changes down to the lung periphery, characterized by CT parametric response mapping indices (PRMfSAD,PRMEmph).
