High-resolution 3D-MERGE technique based black-blood
imaging has been reported to quantitatively measure
carotid atherosclerotic plaque morphology and tissue
composition, and receive more and more clincial
concerns. However, it brings about relative long time
consuming due to the use of motion-sensitized
preparation, which can increase the probability of
motion artifacts due to swallowing, respiration or neck
movements. In our previous research, compressed sensing
(CS) is used to improve temporal resolution by
reconstructing images from a dramatically small number
of data without introducing severe image artifacts[1].
The purposes of this study are: (1) to determine the
reproducibility of the fast 3D-MERGE imaging using CS
reconstruction. (2) to determine the consistency of this
method when using different CS acceleration factors.
