Abstract:: Abstract: Objective To evaluate the efficacy of Radial 3D time of flight (TOF) sequence for magnetic resonance angiography (MRA) of carotid artery. Methods The imaging data of 36 patients who underwent carotid artery MRA using conventional and Radial 3D TOF were collected. Paired-sample t-test was used to compare the signal-to-noise ratio and contrast-to-noise ratio of carotid artery MRA between two sequences, and Wilcoxon signed-rank test was used to compare the subjective score of carotid artery MRA between two sequences. Results Compared with conventional 3D TOF, Radial 3D TOF had higher signal-to-noise ratio, contrast-to-noise ratio (t=25.7, 14.2 P<0.05), and subjective scores (z=-4.36, P<0.05). Conclusion Radial 3D TOF is superior to conventional 3D TOF in displaying carotid artery.
