Suppressing Respiration Effects when Geometric Distortion Is Corrected Dynamically by Phase Labeling for Additional Coordinate Encoding (PLACE) during Functional MRI
Echo planar imaging (EPI) suffers from geometric distortions caused by magnetic field inhomogeneities, which can be time-varying as a result of small amounts of head motion that occur over seconds and minutes during fMRI experiments, also known as "dynamic geometric distortion". Phase Labeling for Additional Coordinate Encoding (PLACE) is a promising technique for geometric distortion correctio...
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 ...
متن کاملUsing PLACE for EPI distortion correction of diffusion weighted images (DWIs)
Introduction An EPI sequence can acquire the k-space signal of an entire slice in a single shot (after a single rf). While this allows for very fast signal acquisition, it comes at the expense of two well-known and important image artifacts: N/2 ghosts and distortion along the phase encode (PE) direction introduced by the inherent sensitivity to B0 inhomogeneity [1]. While there are phase corre...
متن کاملRobust EPI Nyquist ghost elimination via spatial and temporal encoding.
Nyquist ghosts are an inherent artifact in echo planar imaging acquisitions. An approach to robustly eliminate Nyquist ghosts is presented that integrates two previous Nyquist ghost correction techniques: temporal domain encoding (phase labeling for additional coordinate encoding: PLACE and spatial domain encoding (phased array ghost elimination: PAGE). Temporal encoding modulates the echo plan...
متن کاملPhase Angle Tilting (PAT) for Distortion Correction Caused by Susceptibility in EPI
Introduction Gradient-echo EPI as an ultrafast and T2*-sensitive MRI technique, is most commonly used in functional MRI. However, Gradient-echo EPI is vulnerable to susceptibility-induced local field inhomogeneities, which induces signal loss and distortion mostly in the phase encoding direction. Due to susceptibility artifacts, the brain regions near air-tissue and bone-tissue interface are di...
