Abstract:
Objective To explore the effect of competitive respiratory training in patients undergoing abdominal contrast-enhanced magnetic resonance imaging(MRI).Methods A total of 115 patients who un-derwent abdominal contrast-enhanced MRI in the hospital from October 2021 to April 2022 were randomly as-signed to the control group(n=64)and the experimental group(n=51).The control group received routine one-on-one respiratory training,while the experimental group received a competitive respiratory training,wherein the first of the two individuals to achieve qualified breath-holding would undergo scanning first.The duration of respiratory training and scanning,as well as abdominal MRI image quality,were compared between the two groups.Image quality was assessed based on respiratory motion artifact scores,anatomical detail scores,and the percentage of sequences affected by respiratory motion artifacts.Results The average duration of respiratory training in the experimental group was significantly shorter than that in the control group[(39.90±14.26)s vs.(71.31±20.96)s,P=0.001].The difference in total scan time of the abdomen and up-per abdomen was not statistically significant(P＞0.05).The respiratory motion artifact score was higher in the experimental group compared to the control group(P＜0.05).The anatomical detail scores for both the FIESTA and LAVA sequences were higher in the experimental group than in the control group(P＜0.05),while no significant difference was found for the T1 sequence score(P＜0.05).The percentage of sequences affected by respiratory motion artifacts was significantly lower in the experimental group than in the control group(P=0.006).Conclusion Competitive respiratory training can shorten the duration of respiratory train-ing,improve breath-hold quality and persistence,reduce respiratory motion artifacts,and consequently enhance image quality in abdominal contrast-enhanced MRI.
