Coronary vessel wall MR imaging has great potential to detect coronary plaques which can be important for heart disease diagnosis. However, the imaging is always time-consuming because it needs a large amount of data for clear vessel wall depiction. In this work, a novel method based on compressed sensing (CS) with block-weighted total variation (BWTV) was proposed to accelerate coronary vessel wall imaging. Simulation and in vivo experiment results demonstrated that the proposed method can significantly decrease the amount of data for image reconstruction without compromising the depiction of the tiny coronary vessel wall.
