Shear Wave Liver Elastography (SWE)
Shear Wave Liver Elastography is a cutting-edge technology used to measure liver stiffness, which helps in assessing the severity of liver fibrosis. Liver stiffness results from the deposition of fibrous scar tissue during the repair process from damage caused by various chronic conditions.
How it works:
SWE involves an ultrasound scan that doesn't use radiation, offering a painless alternative to traditional liver biopsies. The ultrasound probe emits a "shear wave," and the speed at which this wave travels (measured in kilopascals) helps clinicians determine the severity of the disease, its progression, and the need for treatment.
Benefits of SWE:
- Non-invasive and painless
- No radiation exposure
- Accurate and reliable
- Provides simultaneous imaging, eliminating the need for a separate ultrasound appointment
- Images the entire liver and can detect liver masses
- Allows for easy comparison with previous Fibroscan tests
SWE vs. Fibroscan (Transient Elastography - TE):
SWE is often compared to Fibroscan, another non-invasive technique. However, SWE offers greater accuracy and reliability. Fibroscan is also more expensive.
Cost to the Patient:
This exam is not covered by OHIP. We offer comprehensive liver testing for a low price of $80, which includes stiffness testing, fatty liver testing, and ultrasound imaging.
Preparation:
Please fast for at least 8 hours before the exam. Small quantities of clear fluids and any necessary medications are permitted.
