An ultrasonographic measurement of the gallbladder volume based on an ellipsoid approximation of the gallbladder shape was validated in vivo in the dog. The mean difference between the ultrasonographically determined and the true gallbladder volumes amounted to 2.0 +/- 1.6 cm3 (mean +/- SD), whereas the regression line computed for the ultrasonographically measured versus true gallbladder volumes was y = 0.892x + 3.0, r = 0.955, p much less than 0.001. The ultrasonographic method enabled a noninvasive, repetitive measurement of either a meal- or caerulein-induced gallbladder emptying in the dog.
基于胆囊形状的椭圆体近似法对胆囊容积进行的超声测量在犬体内得到了验证。超声测定的胆囊容积与真实胆囊容积之间的平均差值为2.0±1.6 cm³（平均值±标准差），而针对超声测量的胆囊容积与真实胆囊容积计算得到的回归线为y = 0.892x + 3.0，r = 0.955，p远小于0.001。该超声方法能够对犬因进食或注射缩胆囊素引起的胆囊排空进行无创、重复性测量。
