Both cholecystographic and sonographic analysis of the contraction of the gallbladder showed good correlation between relative decrease of gallbladder width and relative decrease of the area or volume (R = 0.86, p less than 0.001, n = 14, R = 0.80, p less than 0.05, n = 7 respectively). Therefore, we used the relative decrease in the width of the gallbladder to predict the relative decrease in volume. The volume was calculated using a formula given in the literature, after determination of the length, width and depth, using realtime sonography. Correlation between the calculated relative decrease of volume of the gallbladder and the predicted value, was good (R = 0.90, p less than 0.01, n = 8). The relative decrease in the width of the gallbladder in the with of the gallbladder! Can therefore represent the Contraction of the whole gallbladder. Due to its simple method of determination it can be recommended as a complement to sonography of the gallbladder. First of all, however, it will be necessary to conduct a study in a relatively large number of healthy volunteers to obtain the reference values.
胆囊造影和超声对胆囊收缩的分析均显示，胆囊宽度的相对减小与面积或体积的相对减小之间具有良好的相关性（分别为R = 0.86，p < 0.001，n = 14；R = 0.80，p < 0.05，n = 7）。因此，我们使用胆囊宽度的相对减小来预测体积的相对减小。在通过实时超声确定胆囊的长度、宽度和深度后，使用文献中给出的公式计算体积。胆囊计算得出的体积相对减小与预测值之间的相关性良好（R = 0.90，p < 0.01，n = 8）。胆囊宽度的相对减小因此可以代表整个胆囊的收缩情况。由于其测定方法简单，故可推荐作为胆囊超声检查的一种补充方法。然而，首先有必要在相对大量的健康志愿者中进行研究以获得参考值。
