Excerpt
Displacement encoding with stimulated echoes (DENSE) is an accurate and reproducible [
1,
2] technique for measuring myocardial strain throughout the cardiac cycle. The strain maps provided could be valuable in dilated cardiomyopathy (DCM) patients where strain has a prognostic value [
3]. However, DENSE acquisitions typically require long breath holds which are difficult for DCM patients. In this work we accelerate DENSE acquisitions by selectively exciting a volume of tissue around the heart. This allows fewer spiral interleaves to be acquired without aliasing and, therefore a shorter breath hold. …
