چکیده
Figure 1. Demonstration of outlier detection based on a simulation data. (a) shows the noise-free peanut-shaped ADC spatial profile obtained from a 2D tensor. (b) depicts results with an extreme outlier. The dotted line represents the measurement data, while the solid line is the fitted ADC profile. (c) shows the error map between the measured ADC and the fitted ADC signals. It clearly demonstrates that the error-curve of the outlier and its neighbors forms a Mexican–hat profile.

Improved, Real-time Artifact Detection and Reacquisiton for Diffusion Tensor Imaging (DTI)
Introduction: In DTI, diffusion tensor is estimated by least square error fit of measured diffusion weighted images (DWI) and b0 images. However, DWIs often suffer from pulsation-caused, subpixel motion artifacts which result in erroneous tensor estimation. To solve this problem, outlier rejection methods, such as RESTORE [1][2], have been proposed in which a tensor is first estimated with all ...

متن کاملExploring the Possibility of Estimating Degree of Glioma Tumors by Measuring Apparent Diffusion Coefficient
Introduction: Most common glioma tumors are tumors of the central nervous system (CNS) which are the cause of about 40 to 50 percent of brain tumors. This type of cancer includes 2 to 3 percent of cancers in the world. Conventional MRI is powerless in the detection and differentiation of benign and malignant tumors. In this case, diffusion weighted imaging (DWI) can create cont...
متن کاملThe 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 کاملMR diffusion tensor imaging and fiber tracking in spinal cord compression.
BACKGROUND AND PURPOSE Spinal cord damage can result in major functional disability. Alteration of the spinal cord structural integrity can be assessed by using diffusion tensor imaging methods. Our objective is to evaluate the diagnostic accuracy of apparent diffusion coefficient (ADC), fractional anisotropy (FA), and fiber tracking in both acute and slowly progressive spinal cord compressions...
