摘要
目的 分析肝细胞特异性对比剂增强磁共振患者动脉期呼吸运动伪影的影响因素,为采取针对性护理干预降低伪影发生率提供参考.方法 回顾性分析233例初次行肝细胞特异性对比剂增强磁共振检查住院患者的临床资料,采用单因素及logistic回归分析确定动脉期呼吸运动伪影的危险因素.结果 30.90％患者发生动脉期呼吸运动伪影.回归分析显示,文化程度、身体质量指数、心力衰竭、慢性阻塞性肺疾病、腹水是肝细胞特异性对比剂增强磁共振动脉期呼吸运动伪影发生的危险因素(均P＜0.05).结论 肝细胞特异性对比剂增强磁共振检查患者动脉期呼吸运动伪影发生率高,影响因素较多.对高风险患者应及时干预,以降低动脉期呼吸运动伪影发生率.
Abstract
Objective To analyze the influencing factors of respiratory movement artifacts in arterial phase in patients who underwent the hepatocyte-specific contrast agent enhanced magnetic resonance imaging(MRI),and to provide reference for targeted interven-tion to reduce the incidence of artifacts.Methods The clinical data of 233 inpatients who underwent the hepatocyte-specific contrast agent enhanced MRI for the first time were analyzed,retrospectively,and the risk factors of respiratory movement artifacts in ar-terial phase were determined by univariate and logistic regression analysis.Results Respiratory movement artifact in the arterial phase occurred in 30.90％of patients.Regression analysis showed that education level,body mass index(BMI),heart failure,chronic obstructive pulmonary disease,and ascites were the risk factors for respiratory movement artifacts in arterial phase of he-patocyte-specific contrast agent in MRI(all P＜0.05).Conclusion The incidence of respiratory movement artifacts in arterial phase of hepatocyte-specific contrast agent enhanced MRI in patients is high,and there are many influencing factors.Prompt intervention should be made in high-risk patients to reduce the incidence of respiratory movement artifacts in the arterial phase.
