HepaFat-AI is software intended to measure triglyceride fat fraction in magnetic resonance images of the liver, also called volumetric liver fat fraction (VLFF).
Its filing describes an automated analysis system that processes MRI image data and produces a report with VLFF, proton density fat fraction (PDFF) and steatosis grade.
Listed Item
Standalone software platform designed to automatically analyse within seconds magnetic resonance imaging (MRI) datasets to generate an estimate of the patient’s volumetric liver fat fraction (VLFF), converted into proton density fat fraction (PDFF) and steatosis grade. No user input is required for the analysis thus minimising the impact of human error on obtained results. HepaFat-AI is intended for quantitative measurement of the triglyceride fat fraction in magnetic resonance images of the liver, also known as volumetric liver fat fraction (VLFF). It utilises magnetic resonance images that exploit the difference in resonance frequencies between hydrogen nuclei in water and triglyceride fat. The quantitative triglyceride fat fraction is based on the measurement of a magnetic resonance parameter that reflects the ratio of the proton density signal of triglyceride fat to the total proton density signal in the liver. When interpreted by a trained physician, the results provide information that can aid in diagnosis. HepaFat-AI is indicated to: • Assess the volumetric liver fat fraction, proton density fat fraction and steatosis grade in individuals with confirmed or suspected fatty liver disease; • Monitor liver fat content in patients undergoing weight loss management; • Aid in the assessment and screening of living donors for liver transplant.
What the Filing Describes
The FDA filing says the software is indicated to assess VLFF, PDFF and steatosis grade in people with confirmed or suspected fatty liver disease. When interpreted by a trained physician, results can support monitoring liver fat during weight-loss management and assessment and screening of living liver donors.
The system requires MRI images acquired according to the HepaFat-Scan protocol. Its report includes results, confidence intervals and normal ranges. The filing describes intended uses and outputs.
