Key result
3D magnetization-prepared true-FISP substantially increased signal-to-noise ratio by 55% and contrast-to-noise ratio by 178% for coronary arteries compared to FLASH.

Deshpande et al. (2001) studied Coronary artery imaging. 3D magnetization-prepared true-FISP vs. FLASH (fast low-angle shot) was evaluated on Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) (SNR +55%, CNR +178%). 3D magnetization-prepared true-FISP substantially increased signal-to-noise ratio by 55% and contrast-to-noise ratio by 178% for coronary arteries compared to FLASH.
