ABSTRACT
Increased soft-tissue opacity in the region of the canine gallbladder is incidentally detected on radiographs. We hypothesized that there is a difference in the detection of gallbladder sediment on radiographs depending on the amount or mobility of the sediment. In this retrospective and analytical study, we aimed to assess the ultrasonographic features of gallbladder sediment that were detected radiographically. We also aimed to assess the differences in the detection of increased opacity of the gallbladder between radiographic views. We included 223 dogs that underwent thoracic radiography, abdominal radiography, and gallbladder ultrasonography. Ultrasonographic images of the gallbladder were divided into five groups group 1, gravity-dependent sediment occupying < 50% of the gallbladder; group 2, gravity-dependent sediment occupying ≥50%; group 3, sediment attached to the gallbladder wall; group 4, sludge ball; and group 5, gallbladder mucocele. Dogs showing increased opacity on subjective assessment of any radiographic view were recorded, and the sensitivity of radiographic views for detecting gallbladder sediment was analyzed. Of 168 dogs with gallbladder sediment, 37 had increased opacity on at least one radiographic projection. The frequency was compared as a percentage within each category, and Group 4 was the highest percentage with increased radiographic gallbladder opacity, followed by Groups 2 and 5. The sensitivity for detecting increased opacity was highest in the thoracic ventrodorsal view. Thus, in dogs with increased gallbladder opacity on radiographs, large amounts of gallbladder sediment, sludge balls, and gallbladder mucocele should be considered differential diagnoses. In addition, the thoracic ventrodorsal view is recommended to evaluate gallbladder opacity.
