Elastography, particularly with the **FibroScan** device, is a non-invasive method used to measure liver stiffness, which serves as an indicator of liver fibrosis. The procedure involves placing a probe on the skin overlying the right lobe of the liver, typically between the ribs. The device emits low-frequency vibrations that create shear waves within the liver tissue. The speed at which these waves travel correlates with the liver's stiffness, measured in kilopascals (kPa).
During the procedure, the patient lies supine with the right arm elevated. The operator ensures measurements are taken within a designated region of interest, often represented by blue-coded areas on the monitor, ensuring accuracy. The median value from multiple measurements is used to assess liver stiffness, with normal values ranging from 2.5 to 6.0 kPa.
In the case presented, a mean kPa value of 8.9 was noted, alongside a mildly coarse echotexture on ultrasound. This suggests significant liver fibrosis, typically categorized as F2-F3, indicating moderate liver damage. These findings highlight the need for close monitoring and potential interventions to prevent progression to cirrhosis, emphasizing the importance of early detection and management of liver fibrosis.
