The Artoscan S is intended for diagnostic nuclear magnetic resonance imaging of the hip, leg, knee, ankle, foot, shoulder, elbow, forearm, wrist and hand. The device produces transverse, sagittal, coronal and oblique cross-sectional images, displaying the internal structure of the limbs and joints being imaged. The images that are produced correspond to the spatial distribution of protons (hydrogen nuclei) that check the magnetic resonance properties and depend upon the MR parameters (spin-lattice relaxation time (T1), spin-spin relaxation time (T2), nuclei density, flow velocity and chemical shift). If interpreted by a medical expert, these images can provide diagnostically useful information.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
