The Utility of Diffusion Weighted Magnetic Resonance Imaging in Detection of the Origin of the Brain Solid Metastatic Tumors
Background: Early diagnosis of brain tumors has significant effect on the treatment process. Brain metastatic tumors are usually diagnosed following the neurological symptoms in patients or incidentally after Computerized Tomography (CT) scan and Magnetic Resonance Imaging (MRI) requests of the brain. Objectives: Implementation of a new method for being informed about the origin of brain tumors...
متن کاملDiffusion-tensor imaging in brain tumors
Diffusion-tensor imaging (DTI) is the only novel imaging technique that is able to demonstrate white matter tracts and their structural changes related to different brain pathologies. Diffusion tensor describes the 3D diffusion phenomenon of the protons according to their microenvironmental properties allowing a unique description of the space where this molecular movement takes place. This mod...
متن کاملpreoperative grading of astrocytic supratentorial brain tumors with diffusion-weighted magnetic resonance imaging and apparent diffusion coefficient
background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...
متن کاملcharacterization of soft tissue tumors by diffusion-weighted imaging
conclusion our preliminary results have shown that although there is some overlap between benign and malignant tumors, adding dwi, mr imaging to routine soft tissue tumor protocols may improve diagnostic accuracy. results there was only one patient with a malignant cystic tumor and was not included in the statistical analysis. the median adc values of benign and malignant tumors were 2.31 ± 1.2...
