About this study

Official title: PET-MRI: Evaluation, Optimization and Clinical Implementation

This randomized pilot clinical trial studies how well positron emission tomography (PET)-magnetic resonance imaging (MRI) works compared to standard-of-care PET-computed tomography (CT) in diagnosing patients with cancer, cardiac diseases, or neurologic diseases. PET-MRI combines two imaging methods that can be used to evaluate disease. PET-MRI is similar to standard-of-care PET-CT, but exposes the patient to less radiation. It is not yet known whether PET-MRI produces better image quality than PET-CT in diagnosing patients with cancer, cardiac disease, or neurologic disease.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To assess and optimize image quality of PET and MRI focusing on technical artifacts and their correction.

II. To assess the accuracy of PET quantification based on MR attenuation correction (MRAC) derived from various MRI sequences and reconstruction algorithms including the effect of routinely used Gadolinium-based contrast agents on MRAC.

III. To determine the clinical and diagnostic accuracy of PET-MRI in comparison to standard-of-care diagnostic imaging.

IV. To assess the efficacy and workflow in combining PET and MRI in one single examination as compared to separate imaging studies.

  1. To assess the potential for radiation dose reduction if PET-CT is substituted by PET-MRI, thus avoiding the radiation exposure from the CT-component.

What is being measured

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

  1. Overall Image Quality Scores

    Overall image quality scores obtained from the two imaging modalities will be compared with the hypothesis that hybrid PET-MRI images is as good as PET-CT images or superior (not inferior) to the PET-CT images. Evaluation of overall image quality will be assessed using the following criteria: 1=excellent, 2=good, 3=acceptable, 4=poor, 5=not acceptable. A Wilcoxon (Mann-Whitney) rank-sum test with a 0.100 significance level will be used.

    Measured: Day 1

  2. Lesion Based Standard Uptake Values (SUV)

    Lesion based SUV will be estimated and compared for PET-MR and PET-CT images in normal organs and compared. A two-sided two-sample t-test will be used to show significance of difference.

    Measured: Day 1

  3. Area Under the Receiver Operating Characteristic Curve

    A two-sided z-test will be used to detect the difference in the area under the curve showing the sensitivity, specificity, positive and negative predictive values as well as accuracy of diagnostic information.

    Measured: Day 1

  4. Time Effort Associated With the PET-MRI Versus PET-CT With MRI

    Statistical difference in time between PET-MRI versus sequential approach for PET-CT plus MRI. Workflow with shortest timely efforts and sufficient diagnostic information will be established as routine procedure.

    Measured: Day 1

  5. Radiation Dose Reduction With PET-MRI

    Dose measurements will be used to calculate effective radiation dose in each patient. Dose calculations of effective dose will be used to estimate dose savings in omitting the CT component of PET-CT. Statistical tests will use a 0.10 significance level and will be 2-sided

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A study testing positron emission tomography, computed tomography and magnetic resonance imaging in people with Cardiac Disease and Dementia, run by Case Comprehensive Cancer Center at 1 site in United States.

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 6 inclusion and 7 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: finished, as of the sponsor's last update on 29 Oct 2019. 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 United States. 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?

Yes. Results are posted in the registry (first posted 29 Oct 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Overall Image Quality Scores (time frame: Day 1). The study lists 5 primary outcomes in all. 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2019.
