The FDA has reclassified radiological computer-assisted detection (CAD) and diagnosis (CADx) software from class III (highest risk) to class II (special controls).
Key Details
- 1The FDA finalized the order on June 13, moving CAD/CADx software used in radiology to class II regulation.
- 2Devices affected include software aiding detection and diagnosis on medical images like CT, MRI, and X-ray.
- 3Special controls now apply, such as design verification, validation, and clear labeling requirements.
- 4This change lowers the regulatory burden, enabling access via the 510(k) process instead of De Novo or PMA routes.
- 5Reclassification intends to maintain safety and effectiveness while enhancing patient and industry access to innovative tools.
