Displacement-encoded MRI is a class of imaging sequences and protocols
that are based on the idea of displacement-encoding with stimulated echo (DENSE).
Due to its ability to encode the displacement information over an extended period of
time into the phase value of individual pixels in the image, it is a suitable method for
track tissue motion at high resolution, which is valuable imaging tool in the assessment
of cardiovascular diseases. This chapter describes the application of displacementencoded
MRI in the assessment of ischemic heart disease through strain mapping, and
in the assessment of carotid artery lesions through wall strain measurements in
compliance to arterial pressure fluctuations.
