Omni 128 cm PET/CT imaging system: comparing new scanner with standard PET/CT

Official title: Evaluation of Advancements in PET/CT Imaging

Run by GE Healthcare · NCT07857161 · Data updated 2026-11-12

This study tests a new Omni 128 cm PET/CT scanner by having adults with a planned clinical PET/CT also undergo an extra research scan to compare image quality.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older who have a planned clinically indicated PET/CT scan using standard tracers.

Probably not a fit

Patients who do not receive benefit include those who do not have a comparable standard scan or whose clinical care is unaffected by the additional research imaging.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults already scheduled for a clinically indicated PET/CT will receive an additional research scan on the Omni 128 cm PET/CT. Researchers will compare image quality and data between the standard clinical scan and the Omni system to assess performance. The study involves a single visit with no follow-up and may support regulatory submissions and future imaging technology improvements. Participation is limited to those who meet the eligibility criteria and can provide informed consent.

Why it matters

Potential benefit: If successful, the new Omni 128 cm PET/CT could offer clearer images or faster scans for future patients.

How similar studies have gone: Previous research on new PET/CT systems has shown promise in image quality improvements, but results depend on scanner characteristics and patient factors.

Inclusion Criteria:

* Must have a clinical indicated PET/CT exam scheduled including (but not limited to) one of the following radiopharmaceutical tracers: Fluorodeoxyglucose (FDG or 18F-FDG), 18F-DCFPyL; 68Ga- PSMA; 68Ga Dotatate; 18F Amyloid (18F- Florbetapir, 18F-Florbetaben, or 18F-Flutemetamol), or Other standard PET tracers;
* Age ≥ 18 years old at time of consent;
* Able to provide informed consent; AND,
* Has the necessary mental capacity to understand instructions and is able to comply with protocol requirements.

Exclusion Criteria:

* Who, per the site's SOPs, has any condition that would prevent the clinically indicated PET/CT from proceeding (i.e., pregnancy, breastfeeding, renal impairment, elevated blood glucose, etc.);
* Who were previously enrolled in this study;
* Who need urgent or emergent care;
* Who have any conditions that, in the opinion of the PI or designee, would interfere with the evaluation of the results, constitute a health hazard for the subject;
* Unwilling to have GEHC personnel present during scans; OR,
* Unable to tolerate the exam.
