Multi-contrast weighted imaging methods with a single scan provide efficient means for viewing and characterizing the atherosclerotic plaques. We extend previous studies by establishing a new strategy (CS-BLGDuC) and further reducing scan time with compressed sensing . 16 subjects including 6 healthy volunteers and 10 patients with carotid stenosis were carried out.The scan time of CS-BLGDuC were dramatically reduced compared with conventional 3D TOF and QIR. Superficial vascular calcification was clearly showed in gray blood images. It is feasible for the CS-BLGDuC strategy to depict superficial vascular calcifications and improve scan efficiency without decreasing image quality.
