To be used in conjunction with a Magnetic Resonance Scanner to produce diagnostic images of Carotid structures that can be interpreted by a trained physician.

The Machnet Carotids Coil is designed to provide coverage of the carotid arteries and associated vasculature from the aortic arch through the Circle-of-Willis.

Anatomic Regions: Head and Neck Vasculature. Nuclei Excited: Hydrogen

The indications for use are the same as for standard imaging;

The GE Signa system is indicated for use as an NMR device that produces images that: (1) correspond to the distribution of protons exhibiting NMR signal, (2) depend upon NMR parameters (proton density, spin lattice relaxation time TI, spin-spin relaxation time T2) and (3) display the vasculature of the head and neck regions specifically the carotid arteries and associated soft tissue. When interpreted by a trained physician, these images yield information that can be useful in the determination of a diagnosis.

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