Vocabulary Learning Strategies Used by Extroverted and Introverted Iranian EFL Students

The present study is a research which explores the relationship between introversion/extroversion and the use of vocabulary learning strategies. The participants were 80 male and female EFL students of University of Sistan and Baluchestan who had studied EFL at the university for at least two years and were randomly selected. The participants were selected after excluding those who got L scores...

Fast 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...

Simultaneous multi-slice excitation by parallel transmission using a dual-row pTX head array

Introduction Simultaneous multi-slice (SMS) imaging with receiver arrays allows for greatly accelerated 2D single-shot acquisitions with BOLD or diffusionweighted EPI (1-4), and spirals (5). The commonly used SMS excitation methods require specially designed multi-band (MB) (1,2) or PINS RF pulses (6) to excite N slices. In this abstract we explore the use of parallel transmission (pTX) for SMS...

Diffusion weighted image domain Propeller EPI (DW iProp EPI)

Introduction Geometric distortions in Echo Planar Imaging (EPI) are dependent on two sequence parameters: the phase encoding FOV and the echo spacing between two consecutive ky lines, both of which affect the k-space traversal speed. Assuming that a maximum readout gradient bandwidth is used, the echo spacing can be reduced by decreasing the resolution in the kx (not ky!) direction. Both Short ...
