Lung CT Computer-Aided Detection

Finds and measures nodules on a chest CT, and tracks whether they changed since last time.

One of the older families here, and it has aged into something more useful than it started as.

The original job was finding lung nodules on a CT. The valuable job turned out to be measuring them consistently and comparing them with the last scan. A nodule that has not changed in two years is a very different conversation from one that grew four millimetres.

Humans are reliably bad at eyeballing small volume change across two scans taken months apart. Software is reliably good at it. That is a fair trade.

What the FDA Actually Signed Off On

FDA product code
OEB
FDA name for it
Lung Computed Tomography System, Computer-Aided Detection
Rule number
21 CFR 892.2050
Risk class
Class 2
Medical field
Radiology
The FDA's own wording: To assist radiologists in the review of multi-slice computed tomography (msct) exams of the chest and highlight potential nodules that the radiologist should review. A computer aided diagnosis, lung computed tomography system is a class 3 device under product code NRR.

Before You Sign Anything

  • Ask how it handles prior scans from a different scanner or a different site. Comparison is the whole value and it is where these tools break.
  • Ask which measurement standard it reports in, and whether that matches how your team already follows nodules.
  • Ask about the false positive count per scan. On lung CT it is usually higher than people expect.

Clearance data comes from the FDA's public 510(k) and device classification records through openFDA. A clearance means the FDA agreed the product is close enough to something already on the market, not that the FDA tested it in your hospital. It says nothing about accuracy in your patient mix, your scanners, or your workflow. Confirm the current status and the exact cleared indication on the FDA record before you buy.
