Key result
True FISP cine MR imaging achieved higher contrast-to-noise ratios and better endocardial border detection than standard FLASH sequences.

Short- and long-axis cine magnetic resonance (MR) images were obtained with a standard fast low-angle shot, or FLASH, sequence and a first-generation true fast imaging with steady-state precession (FISP) sequence on a 1.5-T MR imager. Contrast-to-noise ratios and volumetric left ventricular measurements were compared for manual and automatic segmentation. True FISP images were associated with significantly (P<.01) higher contrast-to-noise ratios and allowed better detection of the endocardial border. True FISP images were provided with short acquisition times and excellent contrast between the myocardium and the ventricular lumen.

Barkhausen et al. (2001) reported an observational. True fast imaging with steady-state precession (FISP) cine MR sequence vs. Standard fast low-angle shot (FLASH) cine MR sequence was evaluated on Contrast-to-noise ratios and volumetric left ventricular measurements (p=<0.01). True FISP cine MR imaging achieved higher contrast-to-noise ratios and better endocardial border detection than standard FLASH sequences.
