Distinguishing between hepatic inflammation and fibrosis with MR elastography. An ultrasound machine makes images of organs and structures inside the body.
The machine sends out high-frequency sound waves that reflect off body structures. A computer receives these waves and uses them to create a picture. Unlike with x-rays or CT scans , this test does not expose you to ionizing radiation. You will be lying down for the procedure. A clear, water-based conducting gel is applied to the skin over the abdomen. This helps with the transmission of the sound waves. A handheld probe called a transducer is then moved over the abdomen. You may need to change position so that the health care provider can look at different areas.
You may also need to hold your breath for short periods during the exam. How you will prepare for the test depends on the problem. You will likely be asked not to eat or drink for several hours before the exam. Your provider will go over what you need to do. The meaning of abnormal results depends on the organ being examined and the type of problem. Talk to your provider if you have any questions or concerns.
