Answer

Answer

Advantages of HIDA/DISIDA scanning include assessment of function and simultaneous assessment of the bile ducts. In addition, although a gallbladder may appear normal by ultrasonography, a DISIDA scan can depict an obstructed cystic duct abnormality.

A high bilirubin (>4.4 mg/dL) can possibly decrease the sensitivity of HIDA/DISIDA scanning, and recent eating or fasting for 24 hours may possibly affects findings. In addition, these scans do not image other structures in the area.
