POAS4SPM: a toolbox for SPM to denoise diffusion MRI data [PDF]

, 2013
We present an implementation of a recently developed noise reduction algorithm for dMRI data, called multi-shell position orientation adaptive smoothing (msPOAS), as a toolbox for SPM.

Microstructural parameter estimation in vivo using diffusion MRI and structured prior information. [PDF]

, 2016
Diffusion MRI has recently been used with detailed models to probe tissue microstructure. Much of this work has been performed ex vivo with powerful scanner hardware, to gain sensitivity to parameters such as axon radius.

Hemorrhage in the Wall of Pyogenic Brain Abscess on Susceptibility Weighted MR Sequence: A Report of 3 Cases

Case Reports in Radiology, 2014
Background and Purpose. In pyogenic brain abscess, hemorrhage in the walls is considered exceptional. Recently, hemorrhagic changes in the walls of pyogenic abscess have been demonstrated on susceptibility weighted imaging with 3T MRI.

Longitudinal measurement of the developing grey matter in preterm subjects using multi-modal MRI. [PDF]

, 2015
Preterm birth is a major public health concern, with the severity and occurrence of adverse outcome increasing with earlier delivery. Being born preterm disrupts a time of rapid brain development: in addition to volumetric growth, the cortex folds ...

Multi-centre reproducibility of diffusion MRI parameters for clinical sequences in the brain. [PDF]

, 2015
The purpose of this work was to assess the reproducibility of diffusion imaging, and in particular the apparent diffusion coefficient (ADC), intra-voxel incoherent motion (IVIM) parameters and diffusion tensor imaging (DTI) parameters, across multiple ...

Role of novel magnetic resonance imaging sequences in characterization of ovarian masses

The Egyptian Journal of Radiology and Nuclear Medicine, 2014
Introduction: Differentiating a benign from a malignant adnexal mass would provide a basis for optimal preoperative planning and may also reduce the number of unnecessary laparotomies patients undergoing treatment for benign disease.
