Turbo 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...
متن کاملSingle-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 کاملHigh resolution T2 weighted Lung Imaging with a radial Turbo Spin-Echo Sequence
Introduction: MRI of the lung is still a challenging task due to its inherently low proton density, continuous movement caused by respiration and heartbeat, as well as a very short T2* relaxation time of roughly 1-2 ms at 1.5 T [1]. The latter of which can be overcome by using Spin-Echo type sequences which correct for additional spin dephasing owing to inhomogeneities at the numerous air-tissu...
متن کاملSingle-shot turbo spin-echo diffusion-weighted imaging for retinoblastoma: initial experience.
BACKGROUND AND PURPOSE Retinoblastoma may exhibit variable hyperintensities on DWI, resulting in different values in the ADC maps, depending on their histology and cellularity. However, EP-based DWI has susceptibility artifacts and image distortions, which make DWI of the orbit a challenging technique. The aim of this study was to investigate the feasibility of single-shot turbo spin-echo (HAST...
متن کاملAccuracy of turbo spin-echo diffusion-weighted imaging signal intensity measurements for the diagnosis of cholesteatoma.
PURPOSE We aimed to evaluate the diagnostic accuracy of turbo spin-echo diffusion-weighted imaging (TSE-DWI) at 3 T, for cholesteatoma (CS) diagnosis, using qualitative and quantitative methods with numerical assessment of signal intensity (SI), signal intensity ratios (SIR), and apparent diffusion coefficient (ADC) values. METHODS In this retrospective study, two blinded observers independen...
