Overview
Hepatobiliary iminodiacetic acid (HIDA) with an abnormal gallbladder ejection fraction (<40%) is a supportive criteria for diagnosing biliary dyskinesia but is not required for the diagnosis anymore. Noninvasive procedures that may be used to evaluate and diagnose sphincter of Oddi disorders (SOD) are: ultrasound, HIDA scan, and MRCP.
Other Imaging Findings
Hepatobiliary iminodiacetic acid (HIDA):
- Abnormal gallbladder ejection fraction (<40%) is a supportive criteria for diagnosing biliary dyskinesia, but is not required for the diagnosis anymore.[1][2]
Noninvasive procedures that may be used to evaluate and diagnose sphincter of Oddi disorders (SOD) are:[3]
- Ultrasound (in order to measure the common bile duct (CBD) diameter)
- HIDA scan
- MRCP
