Tractography-based quantitation of diffusion tensor imaging parameters in white matter tracts of preterm newborns.

PURPOSE To evaluate the feasibility of performing diffusion tensor tractography (DTT) to map and quantify the pyramidal white matter tracts of premature newborns. MATERIALS AND METHODS Fourteen diffusion tensor MRI (DTI) examinations of nine premature newborns were evaluated. DTT was performed to segment bilateral pyramidal tracts, using a fiber-tracking algorithm originating in the cerebral ...

Multifiber Deterministic Streamline Tractography of the Corticospinal Tract Based on a New Diffusion Model

In this paper, we build upon a new model, describing the random motion of water molecules in fibrous tissues, to develop a multifiber deterministic tractography algorithm. We apply this algorithm to track the corticospinal tract of the human brain, in both controls and patients with tumors.

Multifiber Deterministic Streamline Tractography of the Corticospinal Tract Based on a New Diffusion Model: Part II

We report new results for the second edition of the MICCAI DTI tractography challenge. We build upon a new model, termed Diffusion Directions Imaging, that describes the random motion of water molecules in fibrous tissues and we utilize it as an input to a multifiber deterministic tractography algorithm. We apply the method to track the corticospinal tract in two patients suffering from tumors ...

Corticospinal Tract Reconstruction with Deterministic Multi-fiber Tractography and Model-based Processing

The reconstruction of the corticospinal tract in the human brain is a clinically important task for both surgical planning and population studies. Diffusion MRI tractography provides an in-vivo and patientspecific technique for mapping the tract’s geometry; however, crossing fibers present a challenge for the standard tensor model. In this paper, we explore the use multi-fiber models that have ...

Corticospinal tract location in internal capsule of human brain: diffusion tensor tractography and functional MRI study.

We attempted to elucidate the corticospinal tract location at the posterior limb of the internal capsule in the human brain. Ten healthy volunteers were recruited. Probabilistic mapping was performed using the functional MRI activation resulting from a hand motor task as region of interest 1 and the corticospinal tract area of the anterior pons as region of interest 2. The average location of t...
