Premarket evidence — what FDA accepted
source quote (p.6)
“The purpose of this Traditional 510(k) Pre-Market Notification is to introduce the following two new Liver Fat Quantification software features:”
source quote (p.8)
“The Liver Fat Quantification software feature functionalities allow the end user to perform the following measurements during an ultrasound exam: (1) Attenuation Quantification: a measure of the attenuation coefficient in dB/cm-MHz of a region of interest in the liver (2) Hepato-Renal Index (HRI) Quantification: a ratio measure of the echogenicity (‘brightness') of the liver parenchyma relative to that of the adjacent renal cortex”
