Objective: To study the patients with maintenance hemodialysis(MHD)coronary artery calcium score(CACS)and cardiac MRI assessment of left ventricular ejection fraction(LEVE)、limitation of ventricular wall motion abnormalities(RWMAs)and peak filling rate(PFR)correlation.Methods:We analyzed data from 38 participants with MHD,accepting coronary artery calcification CT scans and MRI cardiac function examinations.Calculating coronary calcium score refer to the coronary artery calcification Agatston quantitative method,and assessing left ventricular ejection fraction(LEVF),limitation of ventricular wall motion abnormalities(RWMAs)and peak filling rate(PFR)of all patients.Consequence:(1)23 cases of 38 patients with MHD CACS is positive,3 cases with 0400.(2)The average left ventricular ejection fraction was(60.3+9.9)%,38 cases,1 case of left ventricular ejection fraction < 40%,5 cases of ventricular wall motion abnormalities have limitations,Higher CACS is associated with lower left ventricular ejection fraction(P < 0.05),a large proportion of participants with lower peak filling rate.(3)Factors such as age adjusted,high limited ventricular wall motion abnormalities and coronary artery calcification have significant correlation(P < 0.05),CACS > 400 limits the incidence of abnormal ventricular wall increased 2.1 times(95%CI:1.30~3.75,P<0.001).Conclusion: Application of coronary artery calcification score can be assessment of atherosclerosis in patients with MHD and limitations of ventricular wall motion abnormalities.Coronary artery calcium score has certain reference value of the occurrence and development of coronary events in patients with MHD.

全脊柱与双下肢全长X线成像顾名思义就是能够将整个脊柱和双下肢全景成像的技术。对于先天性畸形的患者来说,这种技术能够直观的显示出脊柱或者双下肢的形态,并且能够为髋关节、膝关节置换以及下肢脊柱侧弯等畸形矫正患者的术前和术后检查评估提供可靠依据。现在大多数采用的是胃肠透视机来完成全脊柱与双下肢的成像与拼接,而我们则采用的是Philips Digital Diagnost型DR机全脊柱、双下肢摄影功能软件
