ULTRASONOGRAPHY
Ultrasonography has replaced oral cholecystography as the diagnostic procedure of choice because it is rapid and accurate and can be used in patients with liver dysfunction and jaundice. It does not expose patients to ionizing radiation. The procedure is most accurate if the patient fasts overnight so that the gallbladder is distended. The use of ultrasound is based on reflected sound waves. Ultrasonography can detect calculi in the gallbladder or a dilated common bile duct. It is reported to detect gallstones with 95% accuracy.
