What is it indicated for?
The "MAGNETOM Symphony a Tim 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. These images and/or spectra, when interpreted by a trained physician, yield information that may assist in diagnosis.
The "MAGNETOM Symphony a Tim System" may also be used for imaging during interventional procedures performed with MR compatible devices such as, in room display and MR safe biopsy needles.
Indications for use as stated in the FDA summary.
