What is it indicated for?
The MAGNETOM MR system is indicated for use as a magnetic resonance diagnostic device (MIRDD), which produces transverse, sagittal, coronal, and oblique cross sectional images that display the internal structure and/or function of the head, body, or extremities. Other physical parameters derived from the images may also be produced. Depending on the region of interest, contrast agents may be used.
These images and the physical parameters derived from the images when interpreted by a trained physician yield information that may assist in diagnosis.
Indications for use as stated in the FDA summary.
