Objective:To investigate the advantage of sensitivity encoding (SENSE) technique in abdominal dynamic contrast enhanced magnetic resonance angiography (DCE MRA).Methods:Forty patients with clinical suspected abdominal vascular diseases were divided into two groups.Experimental group was performed SENSE technique and the control group was directly carried out DCE MRA scanning.Results:In the control group,thirteen patients got clear images because of good holding of their breath, and 5 cases obtained images of arteries and veins respectively and 8 cases simultaneously.The other 7 cases got images with serious artifacts due to bad breath holding.In experimental groups,all 20 cases got clear images of arteries and veins due to shortening of scanning time.Conclusion:SENSE technique greatly shortens scanning time and obviously improvs DCE MRA images quality and can increase the diagnostic accuracy.
