Paramagnetic gadolinium ions are used as one of the possible contrast agents for magnetic resonance imaging. Contrast agents interact with living cells. An interesting task is to determine how the interaction between the contrast medium and the livin

The two lyotropic liquid crystalline media based on n-alkyl-poly (ethylene) glycols (C8E5 and C12E5) and n-octanol for partial alignment of organic molecules and measured residual constants of dipole-dipole interaction between magnetic nuclei were st

Fiber tractography based on diffusion-weighted MRI provides a non-invasive characterization of the structural connectivity of the human brain at the macroscopic level. Quantification of structural connectivity strength is challenging and mainly reduc

Fiber tracking based on diffusion-weighted magnetic resonance imaging data has become an important tool for studying the human brain structure in vivo, but fiber tracking results need verification. The proposed approach makes it possible to verify fi

Tractography based on diffusion-weighted MRI investigates the large scale arrangement of the neurite fibers in brain white matter. It is usually assumed that the signal is a convolution of a fiber specific response function (FRF) with a fiber orienta

A new approach to estimating the probability of the fiber-track existence has been developed and validated on the basis of digital phantoms and diffusion-weighted magnetic resonance imaging measurements on human brain. The proposed approach includes

Many recent studies reported altered functional connectivity within the frontolimbic circuitry in a wide range of neuropsychiatric disorders. However, functional connectivity must rely on structural connections. In this study we applied a novel proba

Probability mapping of connectivity is a powerful tool to determine the fibre structure of white matter in the brain. Probability maps are related to the degree of connectivity to a chosen seed area. In many applications, however, it is necessary to

BACKGROUND AND PURPOSE: Neuropathologic findings and preliminary imaging studies demonstrated the absence of pyramidal tract and superior cerebellar peduncular decussation in individual patients with Joubert syndrome (JS). We hypothesized that functi
