## Indications for use
The MAGNETOM OPEN viva with the Permanent magnet is an open, whole body scanner. The MAGNETOM Open Viva with the Permanent magnet is indicated for use as diagnostic imaging device to produce transversal, sagittal, coronal and oblique images of the internal structures of the head or body. The images produced by the MAGNETOM OPEN with the permanent magnet reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density, spin lattice relaxation time (T1), spin-spin relaxation time (T2) and flow. When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis.
