متن کاملGradient preemphasis calibration in diffusion-weighted echo-planar imaging.
This article describes a method which enables fast and objective pulse-sequence-specific preemphasis calibration, using standard pulse sequences and system hardware. The method is based on a k-space measurement technique, and has been applied to single-shot, diffusion-weighted, spin-echo, echo-planar imaging (DW-SE-EPI), which is particularly sensitive to eddy-current-induced image distortions....
متن کاملIsotropic resolution in Diffusion Weighted Imaging using 3D multi-slab, multi-echo Echo Planar Imaging
INTRODUCTION Diffusion weighted Magnetic Resonance Imaging (DWI) is usually performed using a 2D single shot echo planar imaging technique, because it generates good SNR, short scan times and is immune to phase differences between diffusion-encoded excitations. 2D DWEPI can be acquired with a reasonably high in-plane resolution, especially if parallel imaging is used to reduce the geometric dis...
متن کاملReadout-Segmented Echo-Planar Imaging in Diffusion-Weighted MR Imaging in Breast Cancer: Comparison with Single-Shot Echo-Planar Imaging in Image Quality
OBJECTIVE The purpose of this study was to compare the image quality of standard single-shot echo-planar imaging (ss-EPI) and that of readout-segmented EPI (rs-EPI) in patients with breast cancer. MATERIALS AND METHODS Seventy-one patients with 74 breast cancers underwent both ss-EPI and rs-EPI. For qualitative comparison of image quality, three readers independently assessed the two sets of ...
متن کاملDetection of middle ear cholesteatoma by diffusion-weighted MR imaging: multishot echo-planar imaging compared with single-shot echo-planar imaging.
BACKGROUND AND PURPOSE Previous reports have shown that DWI is useful in detecting cholesteatoma. SS-EPI is the most widely used DWI technique. However, SS-EPI may have susceptibility artifacts due to field inhomogeneity in the imaging of the temporal bone region. Our purpose was to prospectively evaluate the advantage of MS-EPI for the diagnosis of middle ear cholesteatoma by comparing it with...
