Methods that generate visual representations of the liver, gallbladder, bile ducts, and the blood vessels that nourish the liver, utilized to facilitate the identification of diseases.
Ultrasound scanning stands as the prevailing method for visualizing the liver, while CT scanning and MRI are also frequently employed. Radionuclide scanning can unveil cysts and tumors and provide insights into bile excretion. X-ray imaging procedures encompass cholangiography, cholecystography, and ERCP (endoscopic retrograde cholangiopancreatography), wherein a contrast medium, opaque to X-rays, is introduced to delineate the biliary system. Angiography discloses the blood vessels within the liver.
