What does Cr mean in medicine?

In medicine, Cr means computer X-ray. Or serum creatinine.

CR is the abbreviation of computer X-ray photography. CR is a medical imaging diagnosis of diseases. It uses digital images, which is convenient to access PACS system, and can be combined with computer technology to process images and improve image quality. The price of CR is relatively low, and a set of CR can realize the digitalization of X-ray equipment in the whole hospital.

The abbreviation of serum creatinine, the exact name of serum creatinine (Cr) is serum creatinine, which is generally considered as endogenous serum creatinine, and endogenous creatinine is the product of human muscle metabolism. In muscle, creatine slowly forms creatinine mainly through irreversible non-enzymatic dehydration reaction, and then it is released into the blood and excreted with urine. Therefore, serum creatinine is closely related to the total muscle mass in the body and is not easily affected by diet.

Creatinine is a small molecular substance, which can be filtered by glomerulus and rarely absorbed by renal tubules. Creatinine produced in the body is excreted with urine almost every day, and is generally not affected by urine volume. Clinical detection of serum creatinine is one of the main methods to understand renal function, and it is also an important index of renal function. The increase of serum creatinine means the damage of renal function.

Main advantages of computer X-ray:

The dose of 1.X-ray photography is smaller than that of traditional X-ray photography.

2. Digitize the image for easy access to PACS system.

3.IP board can be placed flexibly, which is convenient for seriously ill patients with mobility difficulties.

4. Compared with DR, the price is low, and a set of CR can realize the digitalization of X-ray equipment in the whole hospital.
