What is it indicated for?

The Hammersmith Endocavitary Coils do not change the intended use of the Picker MR system with which they are used. Picker MR systems are intended for use as NMR devices that produce images that: (1) correspond to the distribution of protons exhibiting NMR, (2) depend upon NMR parameters (proton density, flow velocity, spin-lattice relaxation time T1, spin-spin relaxation time T2) and (3) display the soft tissue structure of the head and whole body.

The Hammersmith Endocavitary Coils do not change the intended use of the Picker MR system with which they are used.

Picker MR systems are intended for use as NMR devices that produce images that: (1) correspond to the distribution of protons exhibiting NMR, (2) depend upon NMR parameters (proton density, flow velocity, 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.

The Hammersmith Endocavitary Coils are indicated for use in the following anatomic regions and with the designated nuclei:

Anatomic Regions: The Anus or Prostate by insertion into the rectum, and the Cervix by insertion into the vagina

Nuclei Excited: Hydrogen

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