Study Overview
Brief Summary
The GE Healthcare Omni Total Body (TB) 128cms (Omni TB) is a long-axial field-of-view (LAFOV) PET/CT scanner and will be installed in a pre-market phase at the Peter MacCallum Cancer Centre.
The main features and functionality of this new scanner include high sensitivity, high resolution digital detectors based on silicon photomultipliers. The ultra-high sensitivity and extended field of view are designed to support the ability to reduce administrated dose and/or shorten acquisition time without compromising the image quality of the PET imaging.
To verify the appearance of images acquired on the Omni TB with images acquired on our conventional PET/CT equipment, a study imaging a cohort of patients on both devices is proposed. The study involves no additional radiopharmaceutical administration.
Additionally, in keeping with ALARA (as low as reasonably achievable) radiation dose practices, it will be possible to model acquisition settings (duration, administered activity and reconstruction parameters) using the system raw data and a suite of research tools to optimise acquisition parameters.

Intervention: PET (Device)
Outcomes
Primary Outcomes

- To compare the quantitative parameters of SUVmean and SUVmax in normal organs on the Omni TB with an existing PET/CT device(1 Day)
- To quantitatively compare the noise characteristics (signal to noise) of images acquired using the Omni TB with an existing PET/CT device(1 Day)
- To compare the quantitative parameters of SUVmean, SUVmax and SUVpeak in up to three candidate lesions visualised on the Omni TB and an existing PET/CT device(1 Day)
- To evaluate the quality of images obtained by the Omni TB with reduced injected radioactivity(1 Day)
- To compare the visibility of lesions in images acquired using the Omni TB with images acquired on an existing PET/CT device(1 Day)
- To evaluate the quality of images obtained by the Omni TB with reduced scan time(1 Day)
