Read the full statement (152 words)
The MAGNETOM systems, Avanto, Espree, Symphony A Tim System, Trio A Tim System, and Verio with software syngo MR B19, are indicated for use as magnetic resonance diagnostic devices (MRDD) that produce transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra, and that display 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 systems, Avanto, Espree, Symphony A Tim System, Trio A Tim System, and Verio with software syngo MR B19, may also be used for imaging during interventional procedures when performed with MR compatible devices such as in-room display and MR-safe biopsy needles.
Indications for use as stated in the FDA summary.
