What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers test whether a portable low-field MRI scanner in the emergency department can help diagnose ischemic stroke faster and guide treatment. The trial enrolls 60 adults who arrive within 6 hours of stroke symptoms and are eligible for clot-busting drugs or clot removal. By comparing times to treatment and recovery with standard care, the study explores if this approach improves outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Portable low-field magnetic resonance imaging scanner
What this could lead to
If it works, this could lead to faster stroke treatment and better recovery for patients, by making diagnosis quicker and more accessible in emergency rooms.
What could go wrong
The trial is small and single-arm, so results may not apply to all hospitals. The portable MRI may not be as accurate as standard scanners, and workflow changes could face practical challenges.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 60 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2024

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age ≥18 years; 2. Diagnosed as ischemic stroke; 3. Eligible for IVT and/or EVT and can be treated within 6 hours of symptom onset (time of symptom onset is defined as the last known normal time); 4. Presenting to AED during working hours (8AM to 6PM, weekdays); 5. Written informed consent from patients or representatives, who understand Cantonese, to participate in this study. Exclusion Criteria: 1. Patients with unstable vital signs who need urgent medical interventions/care; 2. Confirmed contraindications for IVT or EVT by initial assessment (e.g., unstable vital signs, history of severe head trauma within 3 months, known bleeding tendency), before starting brain imaging exams; 3. Claustrophobia or other conditions that are contraindicated for MRI; 4. Patients with pacemakers, brain stimulators or insulin pumps; 5. Patients with medical or other conditions that prevent cooperation with the procedures; 6. Pregnant or breastfeeding women; 7. Participation in other clinical trials within 3 months before screening.
