Overview
Ultrasound
- Gallbladder polyps are typically identified on ultrasonography, which has a sensitivity and specificity of over 90%.

- ERCP (Endoscopic Retrograde Cholangiopancreatography)
- Contrast enhanced CT may aid in the diagnosis with an overall accuracy of 87% for cancer.
- HIDA Scan (Cholescintigraphy): Hepatobiliary iminodiacetic acid scan
- FDG-PET adds little to the CT.
- Importantly, endoscopic ultrasound, which permits detailed evaluation of the gallbladder wall, has excellent diagnostic capabilities and should be used for indeterminate polyps of 5-15 mm.
