This preliminary study found 25 carotid plaques in eighteen patients with 40-99% stenosis degree. Both readers gave their scores of enhanced QIR T1 weighted images (p＞0.05). SNRs were evaluated as 109±21 and 113±18 (p＞0.05) before and after the contrast enhancement. And CNRs were 98±19 and 82±22 (p＞0.05) for the same comparison. Gd-enhanced QIR for carotid plaque imaging can achieve high quality due to good inhibition of blood flow.
