Purpose: To compare image quality, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) of different MRI sequences and the use of parallel imaging (ASSET) at 1.5 and 3.0 T in volunteers. Methods: 20 volunteers were examined at a 1.5 T and 3.0 T MR scanner (GE) both using a 4-element phase array coil. We performed axial Fast Spinecho (FSE)and tagging sequences in short axis, Steady State Free Precession (SSFP) sequences in 2-chamber long and short axis with and without using ASSET. At 3.0 T the flip angle of the SSFP sequences was reduced from 45° to 30°. All other sequence parameters remained constant.…
