K982157 is an FDA 510(k) clearance for the TREX MRI MAGNETIC RESONANCE DIAGNOSTIC DEVICE. Classified as System, Nuclear Magnetic Resonance Imaging (product code LNH), Class II - Special Controls.

Submitted by Field Effects (Tyngsborough, US). The FDA issued a Cleared decision on September 2, 1998 after a review of 75 days - a notably fast clearance cycle.

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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
