pubmed:abstractText |
Three-dimensional (3D) steady-state free precession (SSFP) MRI sequences are often applied to visualize both intra- and extracardiac pathologies. In the present study the contrast behavior of 3D true fast imaging with steady precession (True-FISP) sequences for cardiac imaging was optimized in numerical simulations and compared with measurements obtained in eight healthy volunteers on a 1.5 T whole-body scanner. Two SS preparation schemes in combination with and without a T(2) preparation were assessed to improve contrast between blood and myocardium using a navigator-gated and ECG-triggered 3D True-FISP sequence. Numerical simulations and experimental studies in volunteers showed that an SS preparation using a constant flip angle (CFA) is preferable to a linear flip angle (LFA) preparation in terms of contrast between blood and myocardium. The optimized 3D True-FISP sequence provides a reliable, accurate, and time-efficient means of obtaining a morphological cardiac diagnosis.
