About "Hepatiq", Dr. Hoefs QLSS hepatic function technique VS fibrosis measurements

This company has recently been promoting it's "product" as being FDA approved - their developed "method", their "product" (a sort of "scan/multi-level assessment/analysis") is being touted as a better, fuller, more informative way to assess hepatic "function", than other assesment methods. "QLSS" (Quantitative Liver Spleen Scan) technique of hepatic "function" analysis encompasses at least 3 components, and is compared to other methods that rely more heavily on "fibrosis" level measurements. To get a handle on the intricacies of their testing method(s) they employ, you have to suss all of the old work/publications going back to 2008, 2010, 2014 - Dr. Hoefs work on this QLSS technique. Tiring but interesting!
Here are some links to peruse (about the company/website) and some publications/articles relating to Dr. Hoefs work (to try to get acqauinted with their ideas, arguments and the processes they employ, which they claim is better than what we can be doing with other assessment tools/methods):
