What is transient elastography of the liver?

Transient elastography (FibroScan) is a non-invasive method proposed for the assessment of hepatic fibrosis in patients with chronic liver disease by measuring liver stiffness. It can be easily performed at the bedside or in the outpatients clinic with immediate results and good reproducibility.

Can F4 liver fibrosis be reversed?

Successfully treating the cause of early to moderate liver fibrosis may reverse most, if not all, of the damage that the fibrosis has caused. Nearly every chronic liver condition eventually results in fibrosis, as each condition causes lasting inflammation in the liver.

What does F4 cirrhosis mean?

The cirrhotic stage (METAVIR F4) is broadly classified into two stages: compensated and decompensated, with clinical decompensation being defined by the development of ascites, variceal hemorrhage (VH), encephalopathy, and jaundice.

How accurate is liver elastography?

However, ultrasound elastography is only moderately accurate in the assessment of mild-to-moderate hepatic fibrosis. In our studies, the accuracy of TE was as high as 90% and 93% in the diagnosis of cirrhosis in patients having chronic hepatitis B and C.

Can the liver heal itself from fibrosis?

Fibrosis is the first stage of liver scarring. Later, if more of the liver becomes scarred, it’s known as liver cirrhosis. While some animal studies have shown the potential for the liver to regenerate or heal itself, once liver damage is done in humans, the liver doesn’t usually heal.

How long does it take for fibrosis to turn into cirrhosis?

The onset of liver fibrosis is usually insidious, and most of the related morbidity and mortality occur after the development of cirrhosis (16). In the majority of patients, progression to cirrhosis occurs after an interval of 15–20 years.

Is Stage 4 liver fibrosis the same as cirrhosis?

There is a staging system for fibrosis that ranges from stage 1 to stage 4. As an injured liver progresses from one stage to the next, scar tissue slowly replaces the normal functioning liver tissue. Stage 4 is considered cirrhosis.

Is F4 fibrosis life threatening?

During stage 4, an immense amount of scar tissue has built up. The structure of the scar tissue has created a risk of rupture within the liver. That can cause internal bleeding and become immediately life-threatening.

How is liver stiffness measured in transient elastography?

Transient elastography (FibroScan) is a new, non‐invasive, rapid, and reproducible method allowing evaluation of liver fibrosis by measurement of liver stiffness. In cirrhotic patients, liver stiffness measurements range from 12.5 to 75.5 kPa.

Can a transient elastography be used to measure fibrosis?

Transient elastography does not directly measure fibrosis and hence, false elevations (ie. over-estimation of liver fibrosis) may be observed for several reasons ( Table 1 ). Therefore, liver stiffness readings need to be interpreted carefully, and with consideration to these potential confounding factors.

What do you need to know about elastography?

An elastography is an imaging test that checks for fibrosis, a condition that causes scarring in the liver. Left untreated, fibrosis can lead to cirrhosis and liver failure. But early diagnosis and treatment can reduce or even reverse the effects of the condition.

Which is the best liver elastography in Australia?

One such technique, transient elastography (TE), is a simple, safe and efficient way to estimate liver scarring. FibroScan® (EchoSens, Paris) is the most popular non-invasive device used to assess liver ‘hardness’ (or stiffness) via TE in Australia.
