K131447 is an FDA 510(k) clearance for the INTUITION - TDA, TVA, PARAMETRIC MAPPING. Classified as System, Image Processing, Radiological within the LLZ classification (a category encompassing advanced image processing and PACS-adjacent software), Class II - Special Controls.

Submitted by Terarecon,Inc. (Foster City, US). The FDA issued a Cleared decision on December 24, 2013 after a review of 218 days - an extended review cycle.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.2050 - 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: Incremental AI imaging tool. Moderate-to-high equivalence dependency. Overall, this clearance reflects a predicate-aligned approval typical of modern AI radiology extensions - not a novel clinical breakthrough, but a validated iteration within an established regulatory category.
