Development of an Integrated PET/MR System, Accessories and Components
The PET/MR device components and accessories are under development in order to optimize,
validate and improve the design including improving the quality of images. The purpose of
this study is:
- Aim 1: Perform iterative evaluations of the device (including features and components)
to optimize device performance and assess feasibility of new features;
- Aim 2: Perform activities in support of design validation as needed for regulatory
submission;
- Aim 3: Evaluate device complaints and analyze potential causes.

- Aim 3: Evaluate device complaints and analyze potential causes.
This is a non-randomized, non-statistically powered, single-site, prospective study designed
to gather imaging data for design optimization, regulatory submission and future product
development of an investigational hybrid PET/MRI scanner. Subjects will undergo a clinically
indicated PET/CT exam subsequent to tracer administration. Once clinical imaging is complete,
subjects will be transported to the PET/MR scanner at the General Electric (GE) Facility for
additional imaging. No additional pharmaceuticals or ionizing radiation will be utilized as
part of this study.
