Abstract:
The wall of major arteries undergoes cyclic stretching from the loading of the pulsatile arterial pressure. Atherosclerotic lesions have been shown to localize to regions of excessive stretching of the arterial wall. We developed a displacement-encoded MRI (DENSE) sequence for imaging the motion of the carotid artery wall and mapping the 2D circumferential strain in wall. The sequence utilizes a fully-balanced SSFP readout and achieves 0.6 mm in-plane resolution. Preliminary results in volunteers at 1.5 T and 3.0T support the validity of DENSE mapping of pulsatile strain in the carotid artery wall.
