Readout-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 کاملClinical application of readout-segmented- echo-planar imaging for diffusion-weighted imaging in pediatric brain.
BACKGROUND AND PURPOSE RS-EPI has been suggested as an alternative approach to EPI for high-resolution DWI with reduced distortions. To determine whether RS-EPI is a useful approach for routine clinical use, we implemented GRAPPA-accelerated RS-EPI DWI at our pediatric hospital and graded the images alongside standard accelerated (ASSET) EPI DWI used routinely for clinical studies. MATERIALS ...
متن کاملLumbosacral nerve root avulsions: MR imaging demonstration of acute abnormalities.
Most of the previously reported lumbosacral nerve root avulsions presented with pseudomeningoceles at the time of delayed initial imaging. We report a case of traumatic lumbosacral nerve root injury associated with an isolated femur fracture and demonstrate the evolution of pseudomeningoceles following nerve root avulsions and edema in the perineural fat identified on the initial MR imaging.
متن کاملMulti-Shot, Diffusion-Weighted Imaging at 3T using Readout-Segmented EPI and GRAPPA
D. A. Porter, R. M. Heidemann MR Applications Development, Siemens Medical Solutions, Erlangen, Germany Introduction Diffusion-weighted, single-shot EPI suffers from considerable susceptibility-based distortion artefact at 3T. Although the effects can be mitigated by using a partially parallel imaging (PPA) technique to reduce the effective echo-spacing [1], there are significant residual artef...
متن کاملMagnetic resonance neurography in extraspinal sciatica.
BACKGROUND Sciatica without evidence of lumbosacral root compression is often attributed to piriformis syndrome. However, specific diagnostic tools have not been available to demonstrate sciatic nerve entrapment by the piriformis muscle. OBJECTIVE To evaluate the use of magnetic resonance (MR) neurography in identifying abnormalities of the sciatic nerve in patients with unexplained sciatica....
