What is it indicated for?
The MAGNETOM Terra system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal and oblique cross sectional images and that displays the internal structure and/or function of the head or extremities. Other physical parameters derived from the images may also be produced. These images and the physical parameters derived from the images when interpreted by a trained physician yield information that may assist in diagnosis.
The device is intended for patients > 30 kg/66 Ibs.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
