Read the full statement (127 words)
The Pelvic Array Coil is designed to provide Magnetic Resonance Images of the pelvis, including the hips. The Pelvic Array Coil is designed for use with the GE Signa 1.5T MR scanner.
Anatomic Regions: pelvis, including the hips
Nuclei Excited: Hydrogen
The indications for use are the same as for standard imaging:
The Signa 1.5T 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.
