If it is a 16-row liver scan plus enhancement, the cost of the examination is more than 500 yuan, and at the same time, the price of a bottle of contrast agent is needed. There are expensive and cheap contrast agents, and the price of ordinary contrast agent is usually 300 or 400 yuan. For patients with poor kidney function, they may choose a contrast agent that is less damaging to the kidneys, such as iodixanol, which costs nearly 700 yuan, so the cost of liver enhancement CT is 800 or 900 yuan in total if you choose an ordinary contrast agent. The main purpose of liver enhancement CT is to clarify the lesions in the liver and to consider whether the lesions tend to be benign or malignant based on the way they are enhanced in the liver. Common liver lesions include hemangioma, hepatic adenoma, liver cyst, focal nodular hyperplasia, hepatocellular carcinoma, and liver abscess, all of which can be clearly diagnosed by enhancement CT.
