A liver scan is a diagnostic imaging test that uses a radioactive material to check how well the liver or spleen is working and to assess masses in the liver.
Understanding Liver Scans
A liver scan, also known as a liver scintigraphy, is a nuclear medicine procedure. It offers valuable insights into the liver's function and structure. This scan is particularly useful for:
- Evaluating Liver Function: Assessing how well the liver is performing its various functions.
- Detecting Liver Masses: Identifying abnormal growths or tumors within the liver.
- Assessing Spleen Function: Evaluating the spleen's health and functionality.
How a Liver Scan Works
The process involves injecting a small amount of a radioactive substance (radioisotope) into a vein. This substance is then absorbed by the liver and spleen. A special camera, called a scanner, detects the radioactivity and creates a series of pictures of the liver. These pictures help doctors assess the liver's size, shape, and function. According to the reference material, after a radioisotope has been injected into a vein, a series of pictures are taken of the liver by a scanner.
Benefits of Liver Scans
- Non-invasive: The procedure is generally non-invasive, involving only a simple injection.
- Functional Information: Provides information about liver function, which other imaging techniques may not offer.
- Detailed Imaging: Offers detailed images of the liver and spleen, helping to detect subtle abnormalities.
- Assesses Masses: Liver scans are particularly valuable because it can provide information about liver function, and help assess any masses on the liver.
