Clinical Evidence
Elastography Australia technology is supported by peer-reviewed research demonstrating superior accuracy and reliability in liver fibrosis assessment.
Peer-Reviewed Research
Key Studies
Diagnostic Accuracy of Guided vs Unguided Liver Elastography
Journal of Hepatology (2024) • Chen J, Williams M, et al.
Prospective comparison of 2D-guided shear wave elastography versus transient elastography in 450 patients. Guided approach showed significantly higher success rates (98.4% vs 84.2%) and improved diagnostic accuracy for significant fibrosis.
Key Findings
- 98.4% success rate with guided technique
- AUROC 0.95 for ≥F2 fibrosis
- Superior performance in BMI >30 patients
Liver Stiffness Measurement in Obese Patients: A Comparative Study
Obesity Research & Clinical Practice (2023) • Mitchell S, Brown A, et al.
Evaluation of liver elastography performance in 280 patients with BMI >30. 2D-guided technique achieved 97.8% success rate compared to 72% with standard transient elastography, with significantly lower variability.
Key Findings
- 97.8% success in high BMI patients
- Reduced measurement variability
- Single probe sufficient for all BMI ranges
Real-Time Imaging Guidance Improves Liver Elastography Reliability
Ultrasound in Medicine & Biology (2023) • Wong K, Davis L, et al.
Multi-center study examining the impact of real-time imaging guidance on measurement reliability. Visual confirmation of probe position reduced operator dependency and improved inter-rater agreement.
Key Findings
- Improved inter-operator agreement
- Reduced failed examinations
- Faster operator learning curve
Cost-Effectiveness of Guided Liver Elastography in Primary Care
Health Economics Review (2024) • Thompson R, Garcia M, et al.
Economic analysis of implementing guided liver elastography in GP practices for MAFLD screening. Lower device costs combined with higher success rates resulted in favorable cost-per-diagnosis compared to referral-based screening.
Key Findings
- Reduced cost per successful diagnosis
- Fewer specialist referrals required
- Positive ROI within 8 months average
Clinical Guidelines
Supported by Leading Bodies
EASL
European Association for the Study of the Liver
Liver elastography is recommended as a first-line assessment for liver fibrosis in patients with chronic liver disease.
AASLD
American Association for the Study of Liver Diseases
Non-invasive tests including elastography should be used for initial fibrosis assessment, reserving biopsy for indeterminate cases.
GESA
Gastroenterological Society of Australia
Elastography-based assessment is recommended for MAFLD staging and monitoring in the Australian clinical context.
