The basics of diffusion and perfusion imaging in brain tumors
Perfusion imaging with dynamic susceptibility contrast (DSC)-MRI is based on the principles of tracer kinetic modeling to assess the cerebral microvasculature. 5 In DSC perfusion imaging, a contrast agent is injected into the blood and monitored as it passes through the microvasculature.
Diffusion tensor imaging and fiber tractography
Jul 9, 2024 · Diffusion tensor imaging (DTI) is an MRI technique that uses anisotropic diffusion to estimate the axonal (white matter) organization of the brain. Fiber tractography (FT) is a 3D reconstruction technique to assess neural tracts using data collected by diffusion tensor imaging.
DTI in Diagnosis and Follow-Up of Brain Tumors
Diffusion Tensor Imaging (DTI) maps the diffusion process of water molecules in tissue. The technique is mainly used to visualize brain connectivity and the relation between lesions such as brain tumors and the surrounding white matter tracts.
Magnetic Resonance Imaging of Primary Adult Brain Tumors: …
Knowing the technical aspects, strength and limits of each MR technique is crucial to correctly interpret MR brain studies and to address clinicians to the best treatment strategy. This article aimed to provide an overview of neuroimaging in the assessment of adult primary brain tumors.
Diffusion Tensor Imaging (DTI) Biomarker Alterations in Brain ...
Oct 1, 2024 · Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that provides insights into brain microstructural alterations and tensor metrics and generates tractography to visualize white matter fiber tracts based on diffusion directionality.
Diffusion Magnetic Resonance Imaging in Brain Tumors
Jan 1, 2016 · DTI is an MR method that may be able to delineate more accurately between the core of the tumor, infiltrating tumor, peritumoral edema, and normal brain parenchyma. 26 DTI has been widely used because of its apparent ability to illustrate the relationship of a tumor with the nearby main fiber tracts, though this remains difficult to validate.
Diffusion Tensor Imaging in brain tumors: A study on gliomas …
Nov 1, 2015 · We use Diffusion Tensor Imaging for the diagnosis of brain tumors. Eddy current and motion correction has been applied. We compare results from three different brain tumor types. To explore the role of Diffusion Tensor Imaging in preoperative glioma grading, as well as in differentiation between gliomas and metastatic brain tumors.
Surgical planning in patients with brain glioma using diffusion …
Diffusion-tensor imaging (DTI) is a magnetic resonance imaging (MRI) technique that depicts the integrity of white matter (WM) tracts. This study was conducted to assess the utility of DTI tractography as an imaging technique in assessment of …
Role of MRI in Primary Brain Tumor Evaluation - JNCCN
Nov 4, 2014 · Diffusion tensor imaging (DTI) measures the directional movement of water in at least 6 noncollinear directions. Derivatives of DTI can highlight fiber tract patterns in 3 dimensions and their connectivity.
Diffusion Tensor Imaging - StatPearls - NCBI Bookshelf
Nov 12, 2023 · Diffusion tensor imaging is an advanced magnetic resonance imaging modality that uses the Brownian motion of water molecules to provide data for images. This cutting-edge neuroimaging technique has allowed exploration of the intricate architecture of the brain.
