[Abstract] Objective To investigate the feasibility of modified silent MRA sequence based on hybrid-ASL tagging for the imaging of cerebral arteries. Materials andMethods Continuous silent MRA and modified silent MRA images were obtained from 24 healthy volunteers and 5 patients with cerebral arteriovenous malformations (AVM), who were enrolled in this study. The noise level of the two MRAs was evaluated with subjective assessment and objective measurement. The image quality (IQ) score and signal-to-noise ratio (SNR) of all the segments (including internal carotid artery C1-7, middle cerebral artery M1-2, anterior cerebral artery A1-2, posterior cerebral artery P1-2, vertebral artery, and basilar artery) form the two MRAs were assessed blindly and randomly. The difference of IQ value/signal-to-noise ratio of two MRA images in each segment were analyzed statistically. Finally, the imaging characteristics of improved silent MRA in patients with AVM were observed and analyzed.Results The acquisition noise between the two MRAs were equal (Subjective, P=0.24; Objective, P=0.37). In all of the segments, the IQ score (P=0.021, 0.012, 0.024, 0.043) and SNR (P=0.034, 0.010, 0.033, 0.037) of internal carotid artery C1-4 segment were higher on modified silent MRA than those of continuous silent MRA, while the SNR (P=0.044, 0.016) of internal carotid artery C5 segment was higher on modified silent MRA. In patients with AVM, the modified silent MRA showed more details of feeding arteries, sinuses and draining veins, and had better imaging integrity for small vessels of arteriovenous malformations than that of continuous silent MRA.Conclusions The modified silent MRA could afford to decrease the blurring of the vascular edge and the vascular flow void effect, and improve the signal uniformity, while maintaining the low acoustic noise property. Moreover, this advanced approach could improve the ability to display the details of AVM lesions to a certain extent.
