摘　　要：目的:为了探明1.5T磁共振仪在心脏瓣膜性疾病中的诊断效果。方法:将2019年3月~2020年8月在本院收治的患有心脏瓣膜性疾病的49例患者作为本次研究的研究对象,所选的患者已经签署了知情同意书。结果:通过GE1.5T磁共振以及超声心动图对患者进行检测后所得出的诊断结果一致,对所选的患者进行磁共振定量分析,其中发现主动脉狭窄的患者有14例,主动脉关闭不全的患者有21例,其中主动脉狭窄的患者最大流速可以在317.25~529.74cm/s,平均(411.29±17.46)cm/s,通过超声心动图的诊断主动脉狭窄的患者最大的流速为305.14~521.47cm/s,平均(410.43±24.17)cm/s,两种方法没有显著的差异(t=0.132,P>0.05)。结论:磁共振技术是一种较为先进的技术,其具有丰富的成像序列技术,并且可以从多个方面对心脏瓣膜性的疾病进行定量评价,且在精准度上优于传统的方法,适合在临床上进行量化推广使用。本文同时为心脏瓣膜性疾病诊断的相关研究提供了理论参考依据。Objective:To explore the diagnostic effect of 1.5T MRI in valvular heart disease.Methods:49 patients with valvular heart disease treated in our hospital in March 2019~August 2020 were studied,THE selected patient has signed an informed consent.Results:The diagnostic results obtained by GE1.5T magnetic resonance imaging and echocardiography were consistent.The selected patients were quantitatively analyzed by magnetic resonance imaging.Among them,14 patients were found to have aortic stenosis and aortic insufficiency.There are 21 patients with aortic stenosis.The maximum flow rate of patients with aortic stenosis can be 317.25~529.74cm/s,with an average of(411.29±17.46)cm/s.The maximum flow rate of patients with aortic stenosis diagnosed by echocardiography is 305.14~521.47cm/s,average(410.43±24.17)cm/s,there was no significant difference between the two methods(t=0.132,P>0.05).Conclusion:MRI is a more advanced technique,it’s rich in imaging sequence technology,and we can quantitatively evaluate valvular heart disease in many ways,and in terms of accuracy,it is suitable for clinical quantitative popularization.This paper also provides a theoretical reference for the diagnosis of valvular heart disease.
