Trial summary

This study will compare the time it takes to scan a patient in the emergency department with a portable MRI when compared to a conventional MRI. Participants will be randomized to receive a portable MRI plus standard of care (SOC) vs SOC. Investigators will look at time to beginning of scan for both. Read more about this study

About this study

This study will compare the time it takes to scan a patient in the emergency department with a portable MRI when compared to a conventional MRI. Participants will be randomized to receive a portable MRI plus standard of care (SOC) vs SOC. Investigators will look at time to beginning of scan for both.

Read the detailed description

The primary objective of this study is to determine whether portable brain MRI reduces the time from scan order to scan start in the emergency department as compared to conventional brain MRI. The secondary objectives of this study are 1) to measure the percentage of scans that are completed after order and the time from order to completion, 2) to compare findings on portable MRI to conventional brain imaging findings, 3) to compare the total length of stay between the portable MRI and conventional MRI groups, and 4) to understand the impact of portable MRI scans on decision making and provider satisfaction based on qualitative surveys administered to a physician endpoint panel. This is a prospective, observational, randomized study. Participants will be recruited from the pool of patients ordered for a brain MRI, with or without contrast and excluding hyperacute MRI, in the emergency department. Participants will be randomized to one of two treatment groups, scan or standard-of-care (SOC). Participants in the scan arm will receive a portable MRI scan as soon as the scanner is available after randomization.

Participants in the SOC arm will not receive a portable MRI scan as part of their initial evaluation. Regardless of randomization arm, all participants will receive their scheduled conventional MRI as usual. Information on each participant's clinical course, conventional imaging, and length of stay will be collected, regardless of treatment group. On a rolling basis, surveys containing deidentified clinical information and portable MRI scans will be administered to a physician panel to assess the impact of portable MRI scans on decision making and provider satisfaction.

What is being measured

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

  1. Time to start of scan

    The primary outcome is time from MRI order to assigned arm scan initiation, analyzed as cumulative initiation at the prespecified time points of 3,6,9, and 12 hours.

    Measured: immediately post MRI (Day 1)

Secondary outcomes (4)
  1. Portable MRI Findings

    The frequency of acute findings (e.g., ischemic stroke, intracranial hemorrhage) using the portable MRI will be compared between groups.

    Measured: immediately post MRI (Day 1)

  2. Length of Stay

    Total Emergency Department length of stay

    Measured: immediately post MRI (Day 1)

  3. Non-Completed Scans

    To document the reasons for non-completion of MRI scans

    Measured: immediately post missed MRI (Day 1)

  4. Time to scan during hospital encounter

    Time in hours from MRI order to scan initiation among participants whose assigned examination was initiated during the same hospital encounter.

    Measured: immediately post MRI (Day 1)

Questions about this trial

What is this clinical trial studying?

A study testing Swoop Plus Mk2.0 in people with Patient Satisfaction and Conventional Magnetic Resonance Imaging, run by Yale University 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 2 inclusion and 18 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 2 Sep 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Time to start of scan (time frame: immediately post MRI (Day 1)). 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 2 Sep 2026.
