Pitfalls in Gallbladder Imaging
• Misidentification of the gallbladder. A loop of
bowel or the IVC can look like a gallbladder. Gut
does peristalsis, IVC has flow on doppler. If
possible you should show that the gallbladder
communicates with main portal triad via the major
lobar fissure.
• Bowel gas, try left lateral decubitus position.
• Contracted gallbladder in non-fasting patient.
• Lack of power to penetrate adipose.
