Abstract: Aim: The atrium septum is tilted in heart. There is an angle between atrium septum and the cross section of body, which is called tilt angles of atrium septum (TAAS) in this study, however this angle has not been specifically mentioned in literatures. In this article TAAS was measured and analysed on axial images of contrast enhanced magnetic resonance (CEMR) of normal heart in order to understand quantitatively and accurately the anatomical structure of heart and to supply anatomical basic for some relevant operation. Method: In this article 180 cases of axial images of CEMR of healthy hearts without any organic or functional heart disease were adopted, TAAS were measured and analysed statistically. Results: On axial images of CEMR of healthy hearts the normal range of TAAS is from 12.43° to 55.60°, the average±SD is 34.36±6.92°, they are independent of sex and age as well as the position of heart, the distribution is relatively concentrated, the individual difference is rather small.
