Understanding Hepatoscope-Derived Fat Fraction (HDFF): A Breakthrough in Bedside Liver Care

Quantitative assessment of liver fat has traditionally required Magnetic Resonance Imaging (MRI)—a costly and often inaccessible diagnostic option for many patients . However, with the FDA 510(k) clearance of E-Scopics’ new Hepatoscope-Derived Fat Fraction (HDFF) technology, point-of-care liver assessment is undergoing a significant paradigm shift .

What is Hepatoscope-Derived Fat Fraction (HDFF)?

HDFF is an objective, quantitative biomarker designed to estimate intra-hepatic fat directly at the point of care . By combining foundational quantitative ultrasound parameters—specifically ultrasound attenuation and backscattering coefficients —HDFF provides an accessible tool for the non-invasive assessment and ongoing clinical management of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) .

Why HDFF is a Breakthrough for Non-Invasive Liver Assessment

1. MRI-Level Accuracy at Ultrasound Speed

While conventional ultrasound typically only provides qualitative information regarding the presence of fatty liver disease , HDFF delivers an objective percentage-based measurement in seconds . Clinically validated against the imaging gold standard, HDFF demonstrated an impressive 0.93 correlation coefficient with the MRI-PDFF reference standard . This brings advanced diagnostic confidence directly into routine bedside clinical workflows .

2. A Unified Ultraportable Solution (Steatosis + Fibrosis)

The Hepatoscope stands out as the only ultraportable solution on the market that combines an FDA-cleared Fat Fraction estimate with real-time 2D Transient Elastography . This unique integration empowers clinicians to comprehensively evaluate both Steatosis (liver fat) and Fibrosis (liver stiffness) simultaneously using a single, portable device during a routine examination .

3. Democratizing Access and Improving Practice Workflows

By shifting quantitative fat measurements from a costly, delayed MRI suite to an immediate point-of-care encounter , HDFF helps primary care physicians, obesity medicine specialists, and endocrinologists identify liver disease early and monitor treatment response more effectively . This is particularly valuable as new medical therapies demand scalable, objective tools to track real-time patient baselines .
