Relationship between rest myocardial perfusion imaging and echocardiography/magnetic resonance imaging in measuring left ventricular diameter
Abstract：Objective To investigate the relationship between rest myocardial perfusion imaging (Rest MPI) and cardiac magnetic resonance imaging(MRI)/echocardiography(Echo) for the evaluation of left ventricular diameter and ischemic level and area.Methods The left ventricular diameter was measured in 121 patients with Rest MPI,MRI and Echo performed in one week following hospitalization.The results of MRI and Echo were compared with those of Rest MPI,and their correlation and agreement were assessed.Results The transverse diameter and the long diameter were significantly lower in Rest MPI than MRI and Echo.There were positive correlations between the transverse diameter of Rest MPI,MRI and Echo(r=0.873,P＜0.01;r=0.867,P＜0.01).There were positive correlations between the long diameter of Rest MPI,MRI and Echo(r=0.868,P＜0.01;r=0.850,P＜0.01).Bland Altman analysis indicated that the left ventricle diameters between Rest MPI,MRI and Echo were in good agreement.Pearson's correlation analysis showed that the ischemic level and area were correlated with the left ventricular transverse diameter (r=0.631,P＜0.01;r=0.642,P＜0.01) and the long diameter (r=0.632,P＜0.01;r=0.641,P＜0.01).Conclusion Rest MPI,MRI and Echo are in good agreements regarding left ventricular diameter.The left ventricular size is correlated with the ischemic level and area.
