ASX Announcement – 29 June 2023
UPDATED HepaFatSmart® CLEARED BY US FDA
Highlights
§
HepaFatSmart® has received US FDA clearance, and will now replace HepaFat-AI®
§
Provides significantly improved diagnostic performance compared with HepaFat-AI®
§
Suitable for monitoring fatty liver diseases including globally endemic NAFLD and NASH
§
HepaFatSmart® will replace HepaFat-AI®, which received US FDA clearance in Dec 2020
Resonance Health Ltd (ASX: RHT) (Resonance Health or Company) is pleased to advise that is has received
regulatory clearance from the United States Food and Drug Administration (US FDA) to market its improved
artificial intelligence (AI) trained liver-fat assessment software-as-a-medical device in the USA, HepaFatSmart®.
HepaFatSmart® will replace HepaFat-AI® in the US which received US FDA regulatory clearance in Dec 2020.
About HepaFatSmart®
HepaFatSmart® is a Software-as-a-Medical Device (SaMD) that automatically analyses magnetic resonance
imaging (MRI) images for the quantitative assessment of a patient’s liver fat. Specifically, it provides clinicians
with three liver fat biomarkers; volumetric liver fat fraction (VLFF), proton density fat fraction (PDFF), and a
steatosis grade.
HepaFatSmart® has been trained utilising AI against HepaFat-Scan®, Resonance Health’s established manual
analysis service for assessing liver fat, as the reference standard. HepaFat-Scan® is regulatory cleared for
marketing and use in the USA, Australia, and the European Union.
HepaFatSmart® offers significantly improved diagnostic performance compared with Resonance Health’s
existing AI trained automated liver fat assessment device, HepaFat-AI®, which it will replace in all markets once
the required regulatory clearances for the new device are obtained.
Unlike HepaFat-AI®, which also used a neural network to predict the VLFF, PDFF and steatosis grade,
HepaFatSmart® more closely simulates the manual analysis approach performed by the Company’s highly
trained analysts by defining a liver region of interest (ROI) on acquired MRI images for HepaFat-Scan®.
The sensitivities and specificities of HepaFatSmart® for predicting HepaFat-Scan® VLFF values in the validation
dataset are provided in Table 1 below and range from 98% to 100%. HepaFatSmart® can be accessed through
the Company’s cloud-based user portal, or via onsite platforms which include third parties’ (channel partner)
platforms.
Resonance Health Managing Director, Mitchell Wells commented:
“HepaFatSmart® is our first software-as-a-medical device to receive US FDA regulatory clearance, developed
entirely in-house by Resonance Health’s AI Development Project Team. The team worked closely with the
Company’s experienced technical analysts to develop a new and materially improved approach to training
HepaFatSmart® that more closely emulates the HepaFat-Scan® manual analysis methodology, achieving a
sensitivity and specificity of 98-100%, versus HepaFat-Scan®. This is one of several initiatives completed in
recent months that collectively serve to significantly de-risk and improve the business into the future while
ensuring we have control of our corporate destiny”.

used globally by clinicians in the management of human diseases and by pharmaceutical and therapeutic
companies in their clinical trials. Resonance Health has gained endorsement by leading physicians worldwide
for providing high quality quantitative assessments essential in managing diseases and drug development.
Resonance Health’s dedication to scientific rigour and quality has enabled it to achieve regulatory clearances
for a range of Software-as-Medical Devices (SaMDs) in the USA, Europe, UK, and Australia, and to proudly
carry ISO 13485 certification for the design and manufacture of medical devices. Regulatory cleared SaMD
products, some of which incorporate Artificial Intelligence (AI), include:
§ FerriScan®, a core-lab product that provides an accurate assessment of liver iron concentration (LIC)
through non-invasive MRI-based technology, for use in the assessment of individuals with iron overload
conditions. Internationally recognised as the gold standard in LIC assessment.
§ FerriSmart®, an AI-trained, non-invasive MRI-based device for the automated real-time assessment of LIC
in patients, calibrated against the global gold standard, FerriScan®.
§ HepaFat-Scan®, an MRI-based solution which provides a reliable non-invasive assessment of liver-fat in
liver tissue for use in the assessment of individuals with confirmed or suspected fatty-liver-disease.
§ HepaFatSmart®, an AI-trained, non-invasive device for the automated real-time multi-metric assessment
of liver-fat in patients, for the assessment of individuals with confirmed or suspected fatty liver disease.

§ LiverSmart®, an AI-trained, non-invasive MRI-based multi-parametric device combining FerriSmart® and
HepaFat-AI® into a consolidated report providing accurate assessment of LIC and liver fat.
§ CardiacT2*, the most widely accepted MRI method for assessing heart iron loading. Resonance Health
offers a dual analysis of FerriScan® and CardiacT2*. CardiacT2* is TGA and CE Marking regulatory cleared.
The Company has a development pipeline of additional medical imaging analysis products and services,
including the MRI Liver Fibrosis Project, aimed at accurately assessing the presence and progression of liver
fibrosis utilising non-invasive MRI analysis.
