Cardiac Balanced SSFP 2D Cine DENSE for Myocardial Strain with comparison to Spiral 2D Cine DENSE

Quantification of myocardial strain has been previously demonstrated with echo-planar and spiral sequence versions of Displacement Encoding with Stimulated Echoes (DENSE). However, the non-conventional k-space acquisition of these previous efforts has hindered their integration into mainstream cardiac MRI application. Here we present a more conventional balanced SSFP (bSSFP) version of 2D Cardiac Cine DENSE and compare its performance to 2D Spiral Cine DENSE in normal human subjects. In vivo human scans at 3T demonstrated good agreement of myocardial radial (Err) and circumferential (Ecc) strain values between bSSFP Cine DENSE and Spiral Cine DENSE that also agree with previous literature.
