Delayed contrast enhancement (DCE) imaging is a well-estabished
MRI technique for the evaluation of myocardial tissue.
Segmented k-space imaging, over multiple heartbeats, is
preferred, as usually, a short quiescent phase in the
cardiac cycle needs to be captured. Recently, DCE
imaging has been carried out with cartesian single-shot
sequences, enabling DCE imaging in single heartbeat.
However, the quality of imaging that can replace the
segmented k-space techniques have not yet been
delivered, and thus, faster imaging which can also
maintain image quality is of interest. In this work, we
demonstrate the feasibility of DCE imaging with a
highly-accelerated radial sequence.
