Machine learning in preoperative glioma MRI: Survival associations by perfusion‐based support vector machine outperforms traditional MRI
Journal of Magnetic Resonance Imaging - Tập 40 Số 1 - Trang 47-54 - 2014
Kyrre E. Emblem, Paulina Due‐Tønnessen, John Hald, Atle Bjørnerud, Marco C. Pinho, David Scheie, Lothar R. Schad, Torstein R. Meling, Frank G. Zöllner
PurposeTo retrospectively evaluate the performance of an automatic support vector machine (SVM) routine in combination with perfusion‐based dynamic susceptibility contrast magnetic resonance imaging (DSC‐MRI) for preoperative survival associations in patients with gliomas and compare our results to traditional MRI.... hiện toàn bộ
Diffusion tensor imaging: Concepts and applications
Journal of Magnetic Resonance Imaging - Tập 13 Số 4 - Trang 534-546 - 2001
Denis Le Bihan, Jean‐François Mangin, Cyril Poupon, Chris A. Clark, Sabina Pappatà, Nicolas Molko, Hugues Chabriat
AbstractThe success of diffusion magnetic resonance imaging (MRI) is deeply rooted in the powerful concept that during their random, diffusion‐driven displacements molecules probe tissue structure at a microscopic scale well beyond the usual image resolution. As diffusion is truly a three‐dimensional process, molecular mobility in tissues may be anisotropic, as in ...... hiện toàn bộ
Dynamic coronary MR angiography and first‐pass perfusion with intracoronary administration of contrast agent
Journal of Magnetic Resonance Imaging - Tập 16 Số 3 - Trang 311-319 - 2002

PurposeTo assess the clinical feasibility of a compressed sensing cine magnetic resonance imaging (MRI) sequence of both high temporal and spatial resolution (CS_bSSFP) in comparison to a balanced steady‐state free precession cine (bSSFP) sequence for reliable quantification of left ventricular (LV) volumes and mass.... hiện toàn bộ
Investigation and validation of intersite fMRI studies using the same imaging hardware
Journal of Magnetic Resonance Imaging - Tập 28 Số 1 - Trang 21-28 - 2008
Bradley P. Sutton, Joshua Oon Soo Goh, Andrew Hebrank, Robert C. Welsh, Michael J. Thorpy, Denise C. Park
AbstractPurposeTo provide a between‐site comparison of functional MRI (fMRI) signal reproducibility in two laboratories equipped with identical imaging hardware and software. Many studies have looked at within‐subject reliability and more recent efforts have begun to calibrate responses across sites, magnetic field strengths, and ...... hiện toàn bộ
