Influencing factors of transient elastography in detecting liver stiffness.
Liver stiffness, which correlates well with liver fibrosis stage, can be measured noninvasively by transient elastography, also known as Fibroscan. The present study aimed to determine the independent factors influencing Fibroscan detection by multiple regression analysis. A total of 181 patients who required liver biopsy were enrolled. Liver stiffness measurement (LSM) was detected by Fibrosca...
متن کاملTransient Elastography-Based Liver Stiffness Age-Dependently Increases in Children
BACKGROUND AND AIMS Pediatric use of liver transient elastography (TE) is attractive for its non-invasiveness, but reference values have not been established. We aimed to determine reference values for TE in children. METHODS In pediatric patients (1 to 18 years), TE (FibroScan®) with an M probe was used for both liver stiffness measurement (LSM) and measurement of hepatic fat deposition by u...

متن کاملFibroscan (transient elastography) for the measurement of liver fibrosis.
NHA The Fibroscan device (Echosens) works by measuring shear wave velocity. In this technique, a 50-MHz wave is passed into the liver from a small transducer on the end of an ultrasound probe (Figure 1). The probe also has a transducer on the end that can measure the velocity of the shear wave (in meters per second) as this wave passes through the liver. The shear wave velocity can then be conv...
متن کاملThe Role of Liver Biopsy in the Non-Invasive Methods Era and Liver Stiffness Measurement Using Transient Elastography
Liver biopsy is still the most accurate tool to assess liver histopathology in chronic liver disease (CLD), especially in patients with chronic active hepatitis who need a treatment decision. Nowadays, there are many non-invasive methods are being used to assess liver fibrosis and might replace liver biopsy. One of the new methods is transient elastography (TE/Fibroscan) which has been widely u...
