The Prima I l l TotalSENSE Torso Coil is designed to provide Magnetic Resonance Images of the abdominal and pelvic anatomies. Thie Prima Ill TotalSENSE Torso Coil is designed for use with the Philips lntera 3.OT MRI scanner manufactured by Philips Medical Systems, Inc.
Anatomic Regions: the abdominal and pelvic anatomy, including the liver, spleen, and renal arteries
Nuclei Excited: Hydrogen
The indications for use are the same as for standard imaging:
The 3.OT MRI 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 T1, spin-spin relaxation time T2) and (3)display the soft tissue structure of the head and whole body. When interpreted by a trained physician, these images yield information that can be useful in the determination of a diagnosis.
Indications for use as stated in the FDA summary.
