Ultrashort echo time (UTE) has recently been demonstrated to have potential for the detection of plaque calcification ex-vivo. For this reason, a self-navigated 3D radial, ECG-triggered, whole-heart imaging sequence was adapted to perform free-breathing UTE acquisitions. This pulse sequence aims at taking advantage of the efficiency and ease of use of self-navigation techniques to enable UTE coronary imaging in vivo. A first in vivo human feasibility study was performed and initial results are discussed.
