摘　　要：目的应用磁共振成像初步研究腮腺径线与腮腺体积的相关性,以期用腮腺径线替代体积评价腮腺形态学变化。材料与方法选取健康受试者90名,测量双侧腮腺相关径线及体积,分析其相关性,得出回归方程。同时测量10名2型糖尿病患者腮腺的相关径线,将其值代入回归方程得出体积。结果健康受试者腮腺前后径、上下径与体积呈明显的正相关(前后径相关系数r=0.728,上下径相关系数r=0.720),得出回归方程V=9.506+4.144X+2.190Y(X=前后径,Y=上下径)。受试者腮腺通过回归方程计算所得体积与实测体积比较,总体相符。结论腮腺径线与体积具有明显的相关性,特别是前后径、上下径能够基本反映腮腺的体积变化,从而代替体积测量用于腮腺形态学的初步评估。Objective:The correlation between parotid diameter and parotid volume was preliminarily studied by MRI in order to evaluate the morphological changes of parotid gland with parotid diameter instead of volume.Materials and Methods:The correlation diameter and volume of bilateral parotid gland were measured by 90 healthy subjects,and the correlation was analyzed.The correlation between diameter and volume is analyzed by multivariate linear regression,and the regression equation is obtained.The correlation diameter of parotid gland was measured in 10 patients with type 2 diabetes and the volume was obtained by substituting the value into the regression equation.Results:The anteroposterior and vertical diameters was positively correlated with the volume of the parotid gland of healthy subjects(anteroposterior diameter correlation coefficient r=0.728,vertical diameter correlation coefficient r=0.720),the regression equation was V=9.506+4.144 X+2.190 Y(X=anteroposterior diameter,Y=vertical diameter).There was no significant difference between the measured volume and the calculated volume of parotid gland by regression equation.Conclusions:The anteroposterior diameter,the upper and lower diameter were obvious correlated with the volume of parotid gland,and parotid gland can be easily calculated using the regression equation.Our study provided a simple and easy method for estimate the parotid gland volume.
