What is it indicated for?
The MAGNETOM system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra, and that displays the internal structure and/or function of the head, body, or extremities. Other physical parameters derived from the images and/or spectra may also be produced. Depending on the region of interest, contrast agents may be used. These…
Read the full statement (120 words)
The MAGNETOM system is indicated for use as a magnetic resonance diagnostic device (MRDD)
that produces transverse, sagittal, coronal and oblique cross sectional images, spectroscopic
images and/or spectra, and that displays the internal structure and/or function of the head, body, or
extremities. Other physical parameters derived from the images and/or spectra may also be
produced. Depending on the region of interest, contrast agents may be used. These images and/or
spectra and the physical parameters derived from the images and/or spectra when interpreted by a
trained physician yield information that may assist in diagnosis.
The MAGNETOM system may also be used for imaging during interventional procedures when
performed with MR compatible devices such as in-room displays and MR Safe biopsy needles.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
