Abstract
Introduction Cardiac magnetic resonance (CMR) steady-state free precession (SSFP) images are the reference standard for measuring left ventricular function (LVF) using section summation of short axis images and for analysis of regional wall motion abnormalities (RWMA). Acceleration of this multiple (typically 10-15) breath-hold approach is desirable. Temporal Parallel Acquisition Technique (TPAT) acceleration allows for acquisition of a complete short axis stack in a single breath-hold with limited resolution.
