What this means

A 510(k) is a premarket submission showing the device is substantially equivalent to a legally marketed predicate device. A cleared 510(k) means FDA agreed with that equivalence. Quantitative Total Extensible Imaging (QTxI) went through this pathway (K173444).

openFDA lists it as a Class 2 device under 21 CFR 892.2050. Class II devices are moderate risk and are subject to general and special controls.

Product code LLZ covers 161 devices on the FDA AI list. By decision date, this device is #36 of 161 under that code. AIQ Solutions, Inc. has 1 AI-enabled device on the list, and the Radiology panel accounts for 1,230 in total.

Being on this list doesn't describe how well the device works clinically. Check the FDA record for its indications for use.
