Brief Summary:

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.

Condition or disease Intervention/treatment Phase
Indication for a PET CT Exam Device: PET MR Device Not Applicable

Detailed Description:
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.
