Elective abdominal ultrasonography of a 64 year old woman with past colicky pain but no current pain. It shows a mildly dilated common bile duct with what appears to be a gallstone (black arrow). The green and blue dots are blood flow, since the exam is done as a Doppler ultrasound to distinguish the bile duct from blood vessels.
