Fiber tractography (FT) is a 3D reconstruction technique to assess neural tracts using data collected by diffusion tensor imaging Diffusion Tensor Imaging (DTI) is an magnetic resonance imaging‑based neuroimaging technique that makes it possible to estimate the location, orientation, and anisotropy of the white matter tracts of the brain

Diffusion tensor imaging (DTI) is a newly developed magnetic resonance imaging (MRI) technique that analyzes the anatomy of nerve cells and a complex neuronal network of the brain Diffusion tensor imaging (DTI) comprises a group of techniques where calculated eigenvalues (λ 1, λ 2, and λ 3) and eigenvectors (ε 1, ε 2, and ε 3) are used to create images reflecting various diffusion properties of a tissue. Regular diffusion-weighted (DW) imaging produces images based on only the sum or average of the eigenvalues The most ad- vancedapplicationiscertainlythatoffibertrackinginthe brain, which, in combination with functional MRI, might openawindowontheimportantissueofconnectivity.DTI has also been used to demonstrate subtle abnormalities in a variety of diseases (including stroke, multiple sclerosis, dyslexia, and schizophrenia) and is currently becoming part of many routine clinical protocols The advances in diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), and functional magnetic resonance imaging (fMRI) over the last 20 years have vastly contributed to improving the understanding of the brain structure and function in patients with many diseases of the central nervous system (CNS)

DTI - Questions and Answers in MRI

Magnetic resonance imaging (MRI) studies were performed on a 3T scanner (MR750, GE Healthcare). DTI and T1 -weighted sequences were performed on the tibial and peroneal nerves in the knee. Each subject was scanned on three separate occasions. Image analyses were performed at two anatomic positions: the level of the lateral femoral condyle (position 1), and the superior pole of the patella (position 2). Analysis was performed using three software packages (raters): FuncTools, FSL, and. Functional MRI with DTI Fiber Tracking. The S. Mark Taper Foundation Imaging Center offers diffusion tensor imaging (DTI) fiber tracking and functional (fMRI) motor mapping using magnetic resonance imaging fused with 3D anatomical image of a brain to aid in surgical planning. In doing functional imaging, radiology technicians ask the patient to do a task, such as moving their hands or fingers. Ex-vivo MRI and DTI maps were then compared with histological staining for glial and neuronal abnormalities. The main findings of this paper describe T2, diffusivity and anisotropy markers of tissue change during the acute time period following mild TBI and ex-vivo analyses suggest that MRI and DTI markers are sensitive to subtle cellular alterations in this model. This was confirmed by. DTI-MRI Examination. All subjects were scanned using the 3T Siemens Prisma MR scanner (Siemens Corp., Erlangen, Germany) in CEITEC Masaryk University, Brno, Czech Republic, employing the following sequences: magnetization-prepared rapid gradient-echo (MPRAGE) high-resolution T1-weighted images (240 sagittal slices, slice thickness=1mm, TR=2300ms, TE=2:34ms, FA=8°, FOV=224mm, and matrix.

Diffusion Tensor Imaging (DTI) allows direct in vivo examination of the brain microstructure, white matter tracts, and diffuse axonal injury after suspected Traumatic Brain Injury. DTI is superior to CT and MRI for characterizing Traumatic Brain Injury. With mild to moderate TBI, CTs and MRIs of the brain will often be reported as negative/normal. This does not necessarily mean that TBI has not occurred. This is where DTI plays an important role enhanced (DCE), DTI MRI and PET-CT. We present a review for these methods by surveying the state-of-the-art works. 2.1 DW-MRI Diffusion-weighted magnetic resonance imaging (DW-MRI) is used to measure the mobility of water molecules in the microscopic environment of tissues.

According to various medical studies, DTI, which utilizes MRI technology, is more sensitive to detecting mTBI because it examines damage to the white matter of the brain, whereas MRI scans detect only grey matter injuries. Grey matter abnormalities usually result from direct impact, bruising or tearing of the brain tissue. On the other hand, DTI maps the diffusion process of water through the. Ex vivo MRI and DTI maps were then compared with histological staining for glial and neuronal abnormalities.
