Pre-Processing of BOLD FMRI Data
نویسندگان
چکیده
Pre-processing is necessary in fMRI analysis in order to take raw data from the scanner and prepare it for statistical analysis. This talk describes the various pre-processing steps which occur prior to the the statistical analysis (which estimates where significant activation occurred, and is described in the following talk). The pre-processing steps take the raw MR data and apply various image and signal processing techniques to it that reduce noise and artefacts. These steps are crucial in making the statistical analysis valid and greatly improve the power of the subsequent analyses.

Repeatability of Detecting Visual Cortex Activity in Functional Magnetic Resonance Imaging
Introduction As functional magnetic resonance imaging (fMRI) is too expensive and time consuming, its frequent implementation is difficult. The aim of this study is to evaluate repeatability of detecting visual cortex activity in fMRI. Materials and Methods In this study, 15 normal volunteers (10 female, 5 male; Mean age±SD: 24.7±3.8 years) attended. Functional magnetic resonance images were ob...
متن کاملEffect of Phase-Encoding Reduction on Geometric Distortion and BOLD Signal Changes in fMRI
Introduction Echo-planar imaging (EPI) is a group of fast data acquisition methods commonly used in fMRI studies. It acquires multiple image lines in k-space after a single excitation, which leads to a very short scan time. A well-known problem with EPI is that it is more sensitive to distortions due to the used encoding scheme. Source of distortion is inhomogeneity in the static B0 field that ...

Background: Spatial learning and navigation is a fundamental cognitive ability consisting of multiple cognitive components. Despite intensive efforts conducted with the assistance of virtual reality technology and functional Magnetic Resonance Imaging (fMRI) modality, the music effect on this cognition and the involved neuronal mechanisms remain elusive. Objectives: We aimed to investigate the...
متن کاملEffect of Physiological noise on Thoraco-Lumbar spinal cord fMRI in 3T Magnetic field
Introduction: Functional MRI methods have been used to study sensorimotor processing in the brain and the Spinal cord. However, these techniques confront unwanted contributions to the measured signal from physiological fluctuations. For the spinal cord imaging, most of the challenges are consequences of cardiac and respiratory movement artifacts that are considered as signifi...
متن کاملFunctional MRI of the pre-ictal state.
The mechanisms underlying the transition from interictal to ictal states are poorly understood. Non-linear mathematical analysis of EEG frequency components has confirmed the presence of a pre-ictal state in focal epilepsy. We report on functional MRI (fMRI) analysis of the pre-ictal state in three patients with intractable focal epilepsy. Each subject had a typical partial seizure in the scann...
