Objective To explore the value of gadobutrol enhanced magnetic resonance angiography (MRA) in abdominal artery angiography.Methods The patients were prospectively included for gadobutrol enhanced MRA examination from December 2014 to December 2015. The image quality was assessed by two radiologists. The subjective score and signal intensity were measured for the large and medium arteries, and the subjective score for the small artery was recorded. The Kappa consistency analysis was used to assess the two radiologists’ subjective score.Results All 112 patients were enrolled in this study, 96 of whom were included for the physical examination, 16 of whom were included for the liver tumors. No adverse reactions were found in these patients. The MRA images of 2 patients were affected by the severe respiratory artifact. The MRA images of the other 110 cases were clear and could well show the origins, shapes of large and medium arteries and small arteries. The subjective scores were 21.22±1.93 and 6.24±1.33 of the large and medium arteries and small arteries, respectively. The values of signal noise ratio and contrast signal noise ratio of the large and medium arteries were 1 093.27±331.71 and 897.27±333.29, respectively. The Kappa values of the two radiologists’ subjective score were 0.782 and 0.772 for the large and medium arteries and small arteries, respectively.Conclusions Gadobutrol enhanced MRA can clearly display large and medium arteries, and can also display some small arteries. It has a good application value in abdominal artery angiography.
