The Signa 1.5T TwinSpeed Magnetic Resonance System is a whole body scanner designed for shorter scan times. The Signa TwinSpeed is indicated for use as a diagnostic imaging device to produce transverse, sagittal, coronal and oblique images of the internal structures of the head or body. The images produced by the Signa TwinSpeed system 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.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
