Guided vs Blind Comparison

iLivTouch vs FibroScan

See why clinicians are choosing guided liver elastography over traditional blind point-and-shoot devices. The difference is clear.

FibroScan comparisons on this page refer to commonly deployed standard models (for example 502 Touch, 530 Compact). The FibroScan 630 Expert includes ultrasound localization and additional outputs.

Guided vs Blind: The Core Difference

Understanding why imaging guidance matters for accurate liver assessment.

iLivTouch (Guided TE)

Recommended
  • Real-time B-mode ultrasound imaging shows exact probe position
  • Operator can see liver parenchyma and avoid vessels
  • Visual confirmation of measurement location before acquisition
  • Immediate feedback on positioning quality
  • Reduced operator dependency — you see what you're measuring

FibroScan (Blind VCTE)

Traditional
  • Most installed systems (502/530) have no B-mode for targeting
  • Cannot visualise liver parenchyma during acquisition
  • Relies on external landmarks and operator experience
  • 630 Expert adds localisation — not full guided imaging
  • XL probe mitigates some high-BMI limits but doesn't add visual guidance

FibroScan in high-BMI patients

A primary driver for clinics evaluating alternatives is the performance of traditional blind elastography in obese patients. Published literature indicates that the classic FibroScan M-probe can experience failure rates of 20–25% in cohorts with a BMI > 30.

While the FibroScan XL probe was developed to mitigate this by adjusting the focal depth, it requires purchasing and maintaining a second probe, and the operator is still acquiring measurements without visual confirmation of the liver parenchyma. Guided elastography addresses the root cause by allowing the clinician to see exactly where the shear wave is being generated.

Who should consider the guided alternative?

  • 1
    New clinic setupsAvoid the ~$100k+ capital burden of new legacy systems. Guided elastography is typically a significantly lower capital commitment than comparable new FibroScan, with a faster path to ROI for many practices.
  • 2
    High-BMI cohortsIf your practice manages high volumes of MAFLD, obesity, or type 2 diabetes, 2D guidance is essential for reliable acquisition.
  • 3
    Previous TE failuresClinics frustrated by high IQR ratios or the constant need to switch probes find immediate workflow relief with a universal guided probe.
  • 4
    Primary care screeningWhen evaluating a patient with an indeterminate FIB-4 score, you need a reliable, cost-effective second-line test.

The Verdict

Guided elastography systems supplied through Elastography Australia offer the same core outputs as standard FibroScan workflows, plus real-time imaging guidance that can improve confidence—especially in challenging patients—often at significantly lower capital than comparable new FibroScan.

Common questions

Which is better — FibroScan or elastography?

Both iLivTouch and FibroScan use transient elastography (TE) to measure liver stiffness in kPa. The relevant comparison is between blind TE (FibroScan standard models) and guided TE (iLivTouch). Guided systems use real-time B-mode ultrasound imaging to position the probe before acquisition, which improves success rates in obese patients and reduces operator dependency. Both technologies are clinically validated and guideline-supported.

Is iLivTouch better than FibroScan?

Both devices perform transient elastography (TE) — the same gold-standard technology for liver stiffness measurement. The critical difference is guidance: iLivTouch adds real-time B-mode ultrasound imaging so the operator can see exactly where the measurement is being taken. Standard FibroScan models are blind — the operator cannot visualise the liver during acquisition. For patients with high BMI or narrow intercostal spaces, guided systems achieve significantly higher acquisition success rates.

iLivTouch vs FibroScan — what's the technology difference?

Both use transient elastography: a mechanical vibration creates a shear wave in liver tissue, and the velocity of that wave is converted to a stiffness value in kPa using the elastic modulus equation (E = 3ρV²). The difference is guidance. iLivTouch integrates real-time B-mode ultrasound imaging so the operator can confirm they are measuring appropriate liver parenchyma, avoid vessels, and validate placement before accepting measurements. Standard FibroScan models acquire measurements without this visual confirmation — a limitation that becomes clinically significant in high-BMI patients.
