Optimal Model Mapping for Intravoxel Incoherent Motion MRI.
TL;DR: In this article, the authors proposed an optimal model mapping method to improve the reliability of the perfusion parameter estimation in the IVIM-MRI study, which was applied at 17 b-values ranging from 0 to 2,500 s/mm2.

A comparative study of kernel-based vector machines with probabilistic outputs for medical diagnosis
TL;DR: The extensive empirical study illustrates that the SVM classifier using the tuning-free GMM kernel (SVM-GMM) shows good usability and broad applicability, and exhibits competitive performance against some state-of-the-art methods.

A method for the solution of certain non – linear problems in least squares
TL;DR: In this article, the problem of least square problems with non-linear normal equations is solved by an extension of the standard method which insures improvement of the initial solution, which can also be considered an extension to Newton's method.

MR imaging of intravoxel incoherent motions: application to diffusion and perfusion in neurologic disorders.
TL;DR: A magnetic resonance (MR) method to image intravoxel incoherent motions (IVIMs) by using appropriate gradient pulses and nonuniform slow flow of cerebrospinal fluid appeared as a useful feature on IVIM images.
Journal ArticleDOI
Separation of diffusion and perfusion in intravoxel incoherent motion MR imaging.
TL;DR: Clinical results showed significant promise of the IVIM method for tissue characterization by perfusion patterns and for functional studies in the evaluation of the microcirculation in physiologic and pathologic conditions, as, for instance, in brain ischemia.

The rician distribution of noisy mri data
Hakon Gudbjartsson,Samuel Patz +1 more
TL;DR: The image intensity in magnetic resonance magnitude images in the presence of noise is shown to be governed by a Rician distribution and low signal intensities (SNR < 2) are therefore biased due to the noise.
