Iconography, Commentary with Corresponding Schemata

Abstract

In analysis of the gallbladder, sonography has triumphed, since it has supplanted and even eliminated oral cholecystography. In adults, abdominal ultrasound imaging is carried out with a 3 or 3.5 MHz transducer. It is a rapid, conclusive and reproducible investigation which does not depend upon hepatic function or require the use of ionizing radiation. The only constraint is that it must be performed in a patient who has been fasting for at least 12 h.
