3D Cine DENSE (Displacement ENcoding with Stimulated
Echoes) imaging can offer, compared to tagging, high
spatial resolution, equivalent accuracy and better
reproducibility, and where strain analysis is less time
consuming. However, the scan time is approximately 25
minutes, which is too long for routine clinical use. In
the present study, we accelerated 3D spiral cine DENSE
and shortened the scan time to ~3 minutes. High image
quality was achieved and strain analysis showed expected
values for normal subjects.
