The walkthrough is performed as follows:
- The patient will lie on his back and with his right arm raised behind his head
- The doctor or nurse will apply a small amount of water-based gel to the right side of the patient’s body and place the probe with light pressure
- Ten consecutive measurements will be taken at the same location. The device will measure the state of the liver worldwide, as opposed to a biopsy, where only a small sample is measured;
- The test takes about 10 minutes, and the result is delivered immediately at the end. The result revolves around a number between 1.5 and 75 kPa
- The doctor will evaluate and interpret the results.
FibroScan uses a button-shaped probe placed on the surface of the skin, which gives a series of mechanical impulses (soft shock waves) that travel through the liver. FibroScan measures how quickly these waves travel through the liver and how quickly they recover. In other words, it is the measurement of the speed of the shock wave. Wave speed correlates with liver stiffness, which reflects the degree of fibrosis . The faster the wave travels, the harder your liver is and the more scar tissue you have in your liver. The unit of resistance is measured in kPa. In general, cirrhosis is a concern with a resistance of 12 kPa higher .
The sooner you know the state of your liver, the sooner you can act to prevent irreversible damage . The FibroScan exam gives you a quick and easy way to get an accurate assessment of your liver condition.
