“…The combination of positron emission tomography (PET) and diffusion tensor anisotropy images and functional magnetic resonance imaging (fMRI) data with diffusion tensor anisotropy images has recently been reported (20,21), perhaps alluding to the most obvious application of structural connectivity information, i.e., its integration with the assessment of functional connectivity obtained by means such as PET (22), fMRI (23), or magneto-encephalography (MEG) (24). Fiber tracking could be initiated specifically from centers of brain activation in an attempt to show fiber connections between them.…”

“…Diffusion Tensor Imaging (DTI) is a powerful MRI technique [127,128] that can be used to translate self-diffusion, or microscopic motion of water molecules in tissue into a MRI measure of tissue integrity and structure (white matter fibers). Data from diffusion tensor imaging (DTI) and fMRI have been combined in a few previous studies [129][130][131]. These studies showed that a combination of techniques can give additional information about brain organization which may give more specific information about organization of brain functions and brain injuries.…”

In this review, the authors describe the most recent functional imaging approaches used to explore and identify circuits within networks and model spatially and anatomically interconnected regions. After defining the concept of functional and effective connectivity, the authors describe various methods of identification and modeling of circuits within networks. The description of specific circuits in networks should allow a more realistic definition of dynamic functioning of the central nervous system which underlies various brain functions.

“…12) Diffusion tensor (DT) imaging can probe the structural properties of tissue, such as the integrity and orientation of tracts in the brain, 14,22,30) which cannot be shown by other techniques. DT imaging has been used in the clinical environment to measure the anisotropy of water diffusion in patients with cerebral degeneration diseases.…”

Diffusion tensor (DT) imaging provides quantitative information about the magnitude and the directionality (anisotropy) of water diffusion in vivo and can detect pathologic changes in brain ischemia. This study tried to detect ischemic brain damage using DT imaging in patients with symptomatic chronic major cerebral artery occlusive disease. DT imaging was performed using a 3.0 Tesla magnetic resonance (MR) scanner in 50 patients with unilateral internal carotid artery or middle cerebral artery stenosis or occlusion, who had no obvious infarct lesions on conventional MR imaging. Thirty-three patients underwent DT imaging before and after vascular reconstruction surgery. Fractional anisotropy (FA) was calculated in the middle cerebral artery territory. Preoperative FA values in the ipsilateral side were significantly lower than those in the contralateral side. After surgery, the FA value was significantly increased. DT imaging may indicate ischemic brain damage, not visualized by conventional MR imaging, in patients with major cerebral artery occlusive disease.
