Ingenia 1.5T and 3.0T MRI Systems, Model Numbers: 781396 and 781377, 510(k) #K110151. System units equipped with software version: 4.1.1 are subject to recall/field correction. This MRI system is indicated for use as a diagnostic device. It can produce cross-sectional images, spectroscopic images and/or spectra in any orientation of the internal structure of the head, body, or extremities.

These images and/or spectra, when interpreted by a trained physician, provide information that may assist the diagnosis.

The firm determined that during scanning procedures, for some larger patients, some reddening of the skin of can occur in certain instances due to RF heating when the torso of the patient is positioned within the body coil.
