K925858 is an FDA 510(k) clearance for the OE 1.5 SI. Classified as System, Nuclear Magnetic Resonance Imaging (product code LNH), Class II - Special Controls.

Submitted by Otsuka Electronics (Fort Collins, US). The FDA issued a Cleared decision on December 2, 1993 after a review of 380 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1000 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Radiology review framework, consistent with the majority of Class II 510(k) submissions.
