Single-shot, turbo spin-echo, diffusion-weighted imaging versus spin-echo-planar, diffusion-weighted imaging in the detection of acquired middle ear cholesteatoma.
Diagnosis of acquired middle ear cholesteatoma on MR imaging is mostly done on late postgadolinium T1-weighted MR images and/or echo-planar (EPI) diffusion-weighted (DWI) MR images. We describe the appearance of a case of a complicated attical middle ear cholesteatoma on single-shot (SS) turbo spin-echo (TSE) DWI compared with EPI-DWI. This case suggests a higher reliability of SS TSE-DWI in th...
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...

Y. Han, J. Hwang, J-Y. Chung, H. Park Department of Electrical Engineering, Korea Advanced Institute of Science and Technology, Daejeon, Korea, Republic of Introduction Diffusion tensor imaging (DTI) can provide valuable information regarding brain connectivity and neurological diseases. However, acquiring DTI is not an easy process because it has to be acquired in a short period of time with h...
متن کاملSpin echo versus stimulated echo diffusion tensor imaging of the in vivo human heart
PURPOSE To compare signal-to-noise ratio (SNR) efficiency and diffusion tensor metrics of cardiac diffusion tensor mapping using acceleration-compensated spin-echo (SE) and stimulated echo acquisition mode (STEAM) imaging. METHODS Diffusion weighted SE and STEAM sequences were implemented on a clinical 1.5 Tesla MR system. The SNR efficiency of SE and STEAM was measured (b = 50-450 s/mm(2) ) ...
متن کاملTurbo spin-echo diffusion-weighted MR of ischemic stroke.
PURPOSE Our objective was to determine whether a multisection technique, diffusion-weighted half-Fourier single-shot turbo spin-echo (HASTE) imaging, can compensate for the drawbacks common to other diffusion-weighted techniques; specifically, the need for echo-planar technology and the presence of susceptibility artifacts in areas close to the skull base. METHODS Forty subjects who were refe...
