The most frequent causes of cholestasis include choledocholithiasis andneoplasms (pancreatic head carcinoma, ampullary carcinoma, cholangiocarcinoma). The authors discussedimaging modalities currently applied in the diagnostics of patients with suspected obstruction biliarytract obstruction. Special attention was paid to the efficacy of these techniques in detecting the obstructionand determining its level and nature. In general, US or CT are first performed in patients with cholestasis.The use of percutaneous cholangiography and retrograde cholangiopancreatography is often limited to therapeuticinterventions. Magnetic resonance offers images similar to both conventional cholangiography and computedtomography. This technique offers complex evaluation of bile ducts and other abdominal organs.
