Incorporating Functional MR Imaging into Diffusion Tensor Tractography in the Preoperative Assessment of the Corticospinal Tract in Patients with Brain Tumors

Abstract

BACKGROUND AND PURPOSE:Our goal was to improve the preoperative assessment of the corticospinal tract (CST) in patients with brain tumors. We investigated whether the integration of functional MR imaging (fMRI) data and diffusion tensor (DT) tractography can be used to evaluate the spatial relationship between the hand and foot fibers of the CST and tumor borders.

Corticospinal Tract Extraction Combining Diffusion Tensor Tractography with fMRI in Patients with Brain Diseases

“…5,8,21,22 Although we demonstrated the utility of this method for depicting CST related to local function, attention must be given to errors arising from misregistration between diŠerent images. Our results depicting DTT using this technique agree with those of Smits and associates 23 in similar study.…”

Tract-Specific and Region of Interest Analysis of Corticospinal Tract Integrity in Subcortical Ischemic Stroke: Reliability and Correlation with Motor Function of Affected Lower Extremity

“…An emerging method of reconstructing white matter fibers is by using functional MR imaging-guided fiber tracking technology. This technology has been performed in healthy participants 46 and in patients with brain tumors 47,48 by using DTI. This methodology has potential to be used in patients with stroke for mapping the cortical representations for upper and lower extremity motor function and guiding the placement of seeds for reconstructing CST fibers associated with upper and lower extremity motor function.…”

Diffusion tensor imaging tractography and intraoperative neurophysiological monitoring in surgery of intracranial tumors located near the pyramidal tract

“…Благодаря современным МР-технологиям ней-рохирургам стала доступна информация о функцио-нально важных зонах коры, проводящих путях и ме-таболизме у пациентов с глиомами головного мозга [24][25][26][27]. Одним из самых широко распространенных методов является ДТ-трактография, которая позво-ляет визуализировать основные проводящие пути го-ловного мозга в соответствии с их реальным анато-мическим расположением [12,28].…”
