Both image quality and acquisition time are clinically important for diagnosis and characterization of patients with atherosclerotic disease. Our results demonstrated that GeneRalized Autocalibrating Partially Parallel Acquisitions (GRAPPA) images provide opportunities for improved SNR and CNR, when compared to conventional TSE acquisitions, at reduced acquisition time, especially in T2W images.
