About this study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PETDevice

    This device images the whole body simultaneously with greater sensitivity allowing imaging to occur faster and with less radiation dose compared to conventional PET systems

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To assess the diagnostic quality of images acquired on the OMNI 128 Total Body PET

    To analyse the diagnostic image quality visually on the Omni TB with radiotracers F-18 FDG, F-18 DCFPyL, Ga-68 PSMA, Ga-68 DOTATATE or I-124

    Measured: 1 Day

Secondary outcomes (9)
  1. To compare diagnostic image quality on the Omni TB with an existing PET/CT device

    Three nuclear medicine specialists will qualitatively assess diagnostic image quality using the the 5-point Likert visual grading score. Reviewers will be blinded to the clinical indication, camera model and reconstruction parameters prior to scoring to remove potential bias by expert reviewers.

    Measured: 1 Day

  2. To compare the sharpness and conspicuity of images produced on the Omni TB with an existing PET/CT device

    Three nuclear medicine specialists will qualitatively assess the sharpness and conspicuity of images using the the 5-point Likert visual grading score. Reviewers will be blinded to the clinical indication, camera model and reconstruction parameters prior to scoring to remove potential bias by expert reviewers.

    Measured: 1 Day

  3. To compare the noise characteristics of images acquired using the Omni TB with an existing PET/CT device

    Three nuclear medicine specialists will qualitatively assess the noise characteristics of images using the the 5-point Likert visual grading score. Reviewers will be blinded to the clinical indication, camera model and reconstruction parameters prior to scoring to remove potential bias by expert reviewers

    Measured: 1 Day

  4. To compare the quantitative parameters of SUVmean and SUVmax in normal organs on the Omni TB with an existing PET/CT device

    One nuclear medicine physician will create a region of interest (ROI) around seven normal tissues (kidneys, liver, spleen, muscle, brain, blood pool, and normal lung) to calculate the SUVmean and SUVmax. This assessment will be conducted on all images acquired to allow a comparison between imaging systems

    Measured: 1 Day

  5. To quantitatively compare the noise characteristics (signal to noise) of images acquired using the Omni TB with an existing PET/CT device

    The signal to noise ratio (SNR) will be determined by selecting a volume-of-interest (14cm3) in a region of normal liver. The standard deviation and mean of SUV values within this area will be calculated and used to determine the coefficient of variance (COV) by dividing the SUV standard deviation by the SUVmean. The SNR will then be calculated as the reciprocal of the COV

    Measured: 1 Day

  6. 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

    One nuclear medicine physician will create a spherical 2 cm region of interest (ROI) around up to three candidate lesions to calculate the SUVmean and SUVmax. Target lesion uptake will be determined by placing a 40% isocontour volume of interest (VOI) around the lesion and calculating SUVpeak. This assessment will be conducted on all images acquired to allow a comparison between imaging devices

    Measured: 1 Day

  7. To compare the visibility of lesions in images acquired using the Omni TB with images acquired on an existing PET/CT device

    To quantify the contrast between lesions and surrounding normal tissue the tumour to background ratio will be calculated as a function of the lesion SUVpeak over the SUV in the background. These values will be compared across imaging devices

    Measured: 1 Day

  8. To evaluate the quality of images obtained by the Omni TB with reduced scan time

    Patients imaged using the Omni TB system will have their images acquired for 10 minutes using LIST mode. This raw list mode data will be retrospectively reconstructed so only data over a specified time frame can be evaluated. Time frames will include, 10, 5, 2 and 1 min. These reconstructions will be analysed according to the secondary outcome measures 2 to 8

    Measured: 1 Day

  9. To evaluate the quality of images obtained by the Omni TB with reduced injected radioactivity

    Patients imaged using the Omni TB system will have their images acquired for 10 minutes using LIST mode. This raw list mode data will be retrospectively reconstructed to match the time per bed step used for the conventional PET/CT device. To simulate a lowered injection dose the LIST mode data will undergo Poisson resampling using the following factors, 1/2, 1/4, 1/8, 1/16

    Measured: 1 Day

Questions about this trial

What is this clinical trial studying?

A study testing PET in people with Cancer, run by Peter MacCallum Cancer Centre, Australia at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 8 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess the diagnostic quality of images acquired on the OMNI 128 Total Body PET (time frame: 1 Day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
