Multi-parametric magnetic resonance imaging (mpMRI) offers a unique insight into tumor biology by combining functional MRI techniques that inform on cellularity (diffusion-weighted MRI), vascular properties (dynamic contrast-enhanced MRI), and metabolites (magnetic resonance spectroscopy) and has scope to provide valuable information for prognostication and response assessment. Challenges in th...

The combination of functional Magnetic Resonance Imaging (fMRI) with Electroencephalography (EEG) and Magnetoencephalography (MEG) source reconstruction techniques promises to add temporal resolution in the [ms] range to fMRI activation maps. Depending on the available information, different co-registration methods for merging structural Magnetic Resonance Imaging (sMRI) and fMRI coordinate sys...

The aim of the study is to develop an algorithm for diagnosing cavernous malformations (CM) functionally significant brain localizations. Material and methods. During randomization exclusion patients from general sample (329 patients) 69 were included in study. Patients divided into control groups. Results. Methods preoperative intraoperative diagnostic examinations with CM localizations, inclu...

One of the challenges in functional brain imaging is integration of complementary imaging modalities, such as magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI). MEG, which uses highly sensitive superconducting quantum interference devices (SQUIDs) to directly measure magnetic fields of neuronal currents, cannot be combined with conventional high-field MRI in a single...

This MATLAB interface is aimed at analyzing and integrating two different imaging modalities optical topography system (OTS) and magnetic resonance imaging (MRI). MRI provides information about the anatomical structure of the brain, while OTS displays the changes in the cerebral blood flow in the form of a topographic image. Eight subjects underwent an MRI and OTS exams at Miami Children’s Hosp...

Angiogenesis plays a fundamental role in tumor growth and metastasis. What is needed is a quantitative, noninvasive, and repeatable assay to estimate functional angiogenic activity of the entire tumor. The aims of the present study were to: (a) examine the relationship between functional magnetic resonance imaging (MRI)-based parameters with established histomorphological markers of tumor angio...

CONTEXT Disruption of frontal-subcortical and limbic networks is hypothesized to have a key role in late-life depression (LLD) and can be examined using magnetic resonance imaging (MRI) techniques. Gray matter can be examined using T1-weighted MRI, white matter using T2-weighted MRI and diffusion tensor imaging, and functional connectivity in resting-state networks using functional MRI. Althoug...

Computation of headmodel and sourcemodel from the subject's MRI scan is an essential step for source localization of magnetoencephalography (MEG) (or EEG) sensor signals. In the absence of a real MRI scan, pseudo MRI (i.e., associated headmodel and sourcemodel) is often approximated from an available standard MRI template or pool of MRI scans considering the subject's digitized head surface. In...
