Abstract:
Objective To evaluate the application value of golden angle radial sparse parallel(Grasp)sequence in contrast-enhanced MRI of liver.Methods The imaging data of 30 patients who underwent gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid contrast-enhanced MRI of liver were collected.With the same equipment,images were collected by Grasp sequence and breath-hold sequence separately,with an interval of less than 3 months.The subjective and objective scores of the late arterial phase and portal venous phase images were evaluated.Results There were no significant differences in all subjective scores of the late arterial phase and portal venous phase images between the two sequences(P＞0.05).The signal-to-noise ratio(SNR)of the late arterial phase images in the Grasp sequence was lower than that in the breath-hold sequence(148.4±52.8 vs 195.6±68.4),and the difference was statistically significant(P＜0.01).Although the SNR of the portal venous phase in the Grasp sequence was lower than that in the breath-hold sequence,the difference was not statistically significant(P＞0.05).There was no statistical difference in the other objective scores between the two sequences(P＞0.05).Conclusion The image quality of Grasp sequence in contrast-enhanced MRI of liver can meet the diagnositic requirements,and it is suitable for patients with poor breath-hold capacity,which has important application value.
