dear all.
Ultrasound is not as CT scan. Ultrasound is not able to detect stones in the portion of bile duct behind the duodenum because of the air attenuation present in the duodenum as it is a hollow cavity. Although there is usually no air there but it can cause problems with visualization. Same happens if the person is very fat. Fat causes a lot of problems with ultrasound.
So if asked for MORE ACCURATE. It is definitely CT but the first best test would be Ultrasound

US is good for gall bladder; US is not good enough for e.g. ductus choledochus, so contrast methods are better there
