| Abstract: | Three-dimensional (3D) ultrasonography has been shown to be an accurate and appropriate
tool for measurement of gallbladder volume in humans. Therefore, we applied this novel
technique for the first time to study fasting and postprandial gallbladder volume in 10
healthy dogs and compared the results with those of 2-dimensional (2D) ultrasonography.
Fasting gallbladder volumes determined by 3D ultrasonography were significantly higher
than corresponding volumes determined by 2D ultrasonography (P<0.01).
Additionally, gallbladder volumes were significantly decreased in the postprandial state
compared with the fasting state using 3D ultrasonography (P<0.001),
but 2D ultrasonography showed no significant difference (P=0.189). The
Gallbladder contraction index was higher in 3D ultrasonography than 2D ultrasonography;
however, it did not reach statistical significance (P=0.25). In
conclusion, 3D ultrasonography was able to measure gallbladder volume in healthy dogs in
this study. It is suggested that 3D ultrasonography can be used to accurately estimate
gallbladder volume and contractility. |
