What is it indicated for?

O-scan is a Magnetic Resonance (MR) system that produces transversal, sagittal, coronal and oblique section images of limbs and joints. It is designed for imaging portions of the arm, including hand, wrist, forearm, and elbow, but excluding the upper part of the arm and portions of the leg, including foot, ankle, calf, and knee, but excluding the thigh.

O-scan is a Magnetic Resonance (MR) system that produces transversal, sagittal, coronal and oblique section images of limbs and joints. It is designed for imaging portions of the arm, including hand, wrist, forearm, and elbow, but excluding the upper part of the arm and portions of the leg, including foot, ankle, calf, and knee, but excluding the thigh.

The M.R. images produced by O-scan correspond to the spatial distribution of the protons (hydrogen nuclei) which verify the properties of magnetic resonance and depend on the MR parameters spin-lattice relaxation time (T1), spin-spin relaxation time (T2), nucleus density, flow velocity and “chemical shift”. When interpreted by a medical expert trained in use of MR equipment, the images can provide diagnostically useful information.

Indications for use as stated in the FDA summary.
