چکیده
Fig.4: Temperature changes of a cheese phantom at the hottest voxel during FUS heating experiments. While measurements using GE fast gradient-echo sequence are echo time-dependent (a), the measurements using 2DRF pulse for fat suppression are very similar (b). With excitation pattern of Fig.2d, both fat suppression and 2D excitation were achieved, resulting in improvement in temporal resolution by 2.3 fold as shown in the red line.

متن کامل3D reduced-FOV MR thermometry with fat suppression using a hybrid method combining a 2DRF pulse, parallel imaging, and UNFOLD
Fig.4: Temperature changes of the hottest voxel in 2D cheese experiments. While the conventional sequence (magenta) underestimated temperatures due to the presence of fat, the present method (green) suppressed fat and reduced imaging time by 8-fold. Green line is the result of temporal average over a sliding window of 8 time frames. Fig.2: Excitation profile in a cheese phantom. The distance be...
متن کاملTwo-dimensional spatially-selective RF excitation pulses in echo-planar imaging.
Two-dimensional spatially-selective RF (2DRF) excitation pulses were developed for single-shot echo-planar imaging (EPI) with reduced field of view (FOV) in the phase-encoding direction. The decreased number of k-space lines significantly shortens the length of the EPI echo train. Thus, both gradient-echo and spin-echo 2DRF-EPI images of the human brain at 2.0 T exhibit markedly reduced suscept...
متن کاملFast Cardiac Imaging using a Novel Reduced-FOV Excitation and EPI Acquisition
Introduction: Single-shot cardiac imaging was first proposed by the Mansfield group in the 1977 [1]. We present new RF pulses to increase acquisition speed in conjunction with single-shot and 2interleaved circular EPI readouts. Methods: Experiments were performed on a GE Signa EXCITE 3.0T system using a custom real-time imaging system [2]. Two new reduced FOV excitation pulses [3] were used whi...

Background and objective: Magnetic resonance imaging (MRI) is the most sensitive technique to detect multiple sclerosis (MS) plaques in central nervous system. In some cases, the patients who were suspected to MS, Whereas MRI images are normal, but whether patients don’t have MS plaques or MRI images are not enough optimized enough in order to show MS plaques? The aim of the current study is ...
