Computed tomography (CT) is an important tool in the workup of patients with biliary emergencies. Optimal settings are mandatory to take full advantage of multidetector CT and to obtain the best multiplanar images with the lowest achievable radiation dose. CT is also part of an imaging strategy together with ultrasonography and magnetic resonance imaging. CT is a problem solver in the case of cholecystitis, most often complementary to ultrasonography, especially in the case of complications such as abscesses. CT is also an important tool to assess unusual diseases such as Mirizzi syndrome and ischemic cholangitis. Because CT is a tool that is available 24/7, the radiologist should be familiarize himself or herself with appropriate protocols and with interpretation of common and/or severe diseases, because most of clinical situations will require urgent medical decisions, mainly based on imaging.
