K193271 is an FDA 510(k) clearance for the uAI EasyTriage-Rib. Classified as Radiological Computer-assisted Prioritization Software For Lesions (product code QFM), Class II - Special Controls.

Submitted by Shanghai United Imaging Intelligence Co., Ltd. (Shanghai, CN). The FDA issued a Cleared decision on January 15, 2021 after a review of 416 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.2080 - the FDA radiology and imaging software oversight framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Radiology submissions.

Device Classification

Product Code QFM Radiological Computer-assisted Prioritization Software For Lesions
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 892.2080
Definition Radiological Computer-assisted Prioritization Software For Lesions Is An Image Processing Device Intended To Aid In Prioritization And Triage Of Time Sensitive Patient Detection And Diagnosis Based On The Analysis Of Medical Images Acquired From Radiological Signal Acquisition Systems. The Device Identifies Or Prioritizes Time Sensitive Imaging For Review By Prespecified Clinical Users Based On Software-based Image Analysis But Does Not Provide Information From The Image Analysis Other Than Triage And Notification.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Radiology devices follow this clearance model.
