Shear Wave Elastography (SWE) Liver Elastography
What is Shear Wave Elastography (SWE) Liver Elastography?
Shear Wave Elastography (SWE) also knows as Fibroscan (TM) is a revolutionary, non-invasive medical device that uses ultrasound-based technique to accurately measure liver stiffness—a direct indicator of fibrosis (scarring) in the liver. Unlike a traditional liver biopsy, which requires a needle and carries associated risks, Shear Wave Elastography is a painless, quick procedure performed in a clinic setting, providing immediate and objective results.
By sending a gentle vibration through the liver tissue and measuring the speed of the resulting shear wave, the technology calculates a kilopascal (kPa) score that correlates with specific stages of liver fibrosis (F0-F4). At Gastro Doctor, we offer this advanced diagnostic tool to deliver precise liver health assessments without discomfort or downtime, serving both clinical management needs and specific requirements such as NZ Immigration medicals.
Conditions & Scenarios We Assess
Shear Wave Elastography is a versatile diagnostic tool essential for evaluating, staging, and monitoring a wide range of liver conditions and specific health requirements.
-
Fatty Liver (NAFLD/NASH)
Shear Wave Elastography provides simultaneous measurement of liver stiffness (fibrosis) and fat content (CAP score), making it the ideal non-invasive tool for staging and monitoring fatty liver disease.
-
Chronic Liver Disease Staging & Monitoring
We use Shear Wave Elastography to accurately stage liver fibrosis in chronic conditions, providing a clear F0-F4 score that guides treatment intensity and prognosis. This is crucial for ongoing management and monitoring disease progression or regression in response to therapy.
-
Non-Alcoholic Fatty Liver Disease (NAFLD/NASH)
For the growing number of patients with fatty liver disease, Shear Wave Elastography is the gold-standard non-invasive test. It simultaneously measures both liver stiffness (for fibrosis) and the Controlled Attenuation Parameter (CAP) score to quantify fat content, offering a complete picture of liver health in one quick session.
-
Viral Hepatitis (Hepatitis B & C)
Shear Wave Elastography provides a safe and reliable method to assess the degree of liver damage caused by chronic viral hepatitis. It is used to establish a baseline fibrosis stage, determine the urgency of treatment, and monitor liver health during and after antiviral therapy.
-
Alcoholic Liver Disease
We offer objective assessment of liver fibrosis related to alcohol use. Shear Wave Elastography provides patients and clinicians with a clear metric of liver health, which can be a powerful motivator for change and a tool to monitor improvement with abstinence.
-
Immigration New Zealand Medical Requirements
A primary reason for referral is to fulfil the specific liver fibrosis staging requirement for NZ visa applications. We provide the formal, detailed report that Immigration NZ mandates, formatted to meet their exact specifications, with an understanding of the time-sensitive nature of the process.
-
Unexplained Abnormal Liver Blood Tests
When routine blood tests (LFTs) show persistent abnormalities, Shear Wave Elastography helps answer the critical question of whether significant underlying fibrosis is present, guiding further investigation and management.
-
Pre-Medication & Pre-Surgical Screening
Prior to starting certain medications that may affect the liver (e.g., for rheumatological conditions) or before major surgeries like bariatric procedures, a Shear Wave Elastography offers a safe way to establish a baseline of liver health and ensure patient safety.
Our Shear Wave Elastography (SWE) Service Offering
Comprehensive Assessment Protocol
Every appointment begins with a clinical review of your history and indications. The scan itself is a 10-15 minute, painless procedure where you lie comfortably while a probe is gently placed on your skin over the liver area. We perform multiple measurements to ensure accuracy and consistency in the results.
Immediate Results & Detailed Reporting
The report will include a comprehensive, analysis that clearly states your fibrosis stage (F0-F4), interprets the findings in the context of your health, and includes all necessary details for your GP, specialist, or immigration application. It will also mention liver stiffness measurement (kPa) and CAP score (if applicable) and the report will be sent in 24 hours.
Integrated Specialist Interpretation
Your scan is not just a number. Dr. Dinesh Lal, a Consultant Gastroenterologist and Hepatologist, oversees and interprets every result. He provides expert clinical context, explaining what the results mean for your specific situation and advising on the next steps, whether that’s lifestyle modification, further investigation, or specialist follow-up.
Streamlined Process for Immigration Applicants
We have a dedicated, efficient pathway for immigration scans. We understand the deadlines you face and ensure a seamless process from booking to receiving your formatted report, with clear guidance on how to submit it to Immigration NZ or your panel physician.
Who Needs a Shear Wave Elastography
A Shear Wave Elastography is essential for patients to accurately evaluate scars in the liver and stage the level of fibrosis. It is a cornerstone of management for individuals with chronic hepatitis B or C, providing a safe method to monitor liver damage before, during, and after treatment. Those with alcoholic liver disease benefit from objective staging to assess the impact of alcohol and track improvement with abstinence. The technology is invaluable for monitoring liver fibrosis progression over time in chronic conditions and for assessing treatment effectiveness, offering clear, quantitative data to guide clinical decisions.
For NZ Immigration Requirements
A primary application of SWE is to fulfil the specific formal liver fibrosis staging requirement for visa applications with Immigration New Zealand. We provide a comprehensive report meeting all immigration standards, which includes the necessary kPa score and corresponding METAVIR fibrosis stage (F0-F4). Understanding the time-sensitive nature of applications, we ensure fast results to meet critical immigration deadlines, with same-day reporting as our standard.
The Shear Wave Elastography Advantage
The technology offers significant benefits over traditional assessment methods. It is completely non-invasive, requiring no needles, incisions, or recovery time, eliminating the risks and anxiety associated with liver biopsy.
it uses Ultra-sound technology to access accurate depth of liver and evaluate the level of fibrosis. Thus avoiding aberrancies created by other structures.
The procedure is quick and painless, typically taking only 10 to 15 minutes in our clinic. One of its most powerful features is the provision of immediate results, as data is analysed instantly during your appointment. It is considered a highly accurate, gold-standard technology for liver assessment, validated by extensive clinical research. Furthermore, it is extremely safe, involving no radiation and having no known side effects.
What to Expect During Your Scan
The process is straightforward and designed for your comfort. It begins with simple preparation, involving a 4-hour fast before your appointment to ensure measurement accuracy. During the scan, you will lie comfortably while a small probe is gently placed on your skin over the liver area; you will feel only a mild tapping sensation. The stiffness measurement (your kPa score) is calculated immediately by the device. Following this, a comprehensive formal report is provided, detailing your liver fibrosis stage (F0-F4), which you can discuss directly with Dr. Lal and use for your medical or immigration needs.
