Exemplary systems, methods, and computer-accessible mediums can be provided that can generate resultant data regarding fiber tract(s) and anatomical structure(s). For example, first information related to imaging data of the anatomical structure(s) can be received. Second information related to a predictive model of further fiber tract(s) can be received. The resultant data can be generated based on the first information, the second information and a fiber cost procedure.

System, method and computer-accessible medium for obtaining and/or determining mesoscopic structure and orientation with fiber tracking

An exemplary system, method and computer-accessible medium for determining a plurality of tissue parameters of a tissue(s), can include, for example, receiving information related to a plurality of rotational invariants contained within a diffusion magnetic resonance (dMR) image(s) of the tissue(s), and generating the tissue parameters using a set of rotational invariants related to the plurality of tissue parameters using such information. The tissue parameters can be generated by factorizing a response of an individual fiber segment of the tissue(s) based on the set of rotational invariants. The response of the individual fiber segments can be factorized from an orientational distribution function ('ODF'). The individual fiber segments can be factorized using a scalar tensor factorization(s) of the rotational invariants. The set of rotational invariants can be of a rotation group SO(3).

System, method and computer-accessible medium for determining brain microstructure parameters from diffusion magnetic resonance imaging signal's rotational invariants

A method for measuring the cerebral perfusion of a living organism () by means of magnetic resonance (='MR') imaging proposes acquisition of further MR signals in a slice () that is pervaded by an artery that supplies the blood to the brain in order to determine the temporal progression of the concentration of the contrast medium during the bolus passage in the artery. During acquisition of the further MR signals, a magnetic field gradient is applied in such a way that projection images of the slice are generated. In each time interval between the excitations of the further MR signals, at least one radio-frequency (='RF') pulse is irradiated that causes saturation of the nuclear spin magnetization in the slice. This enables simultaneous measurement of the contrast medium flow in the vessels supplying the brain and the brain tissue within the same sequence with an adapted dynamic range.
