To discuss the clinical application of MR Propeller technique in eliminating the signal loss artifacts of sinus images. 30 cases were performed routine sinus MR examination, underwent Propeller T2 weighted imaging (WI), and the images were compared with IDEAL T2WI sequence. The two image sets were evaluated for overall image quality, signal-to-noise rate(SNR)and contrast-to-noise rate(CNR)´╝îrespectively. The signal loss artifacts were significantly reduced by Propeller T2WI scanning, and the SNR and CNR, image quality were significantly improved. Propeller T2WI technique can obviously reduce the signal loss artifacts by magnetic-susceptibility, and can significantly improve the image quality for clinical diagnosis
