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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study aims to create a detailed brain atlas for healthy Chinese adults by scanning volunteers with MRI machines of different magnetic field strengths, from 0.55T to 7T. The researchers will collect structural, diffusion, and functional images to see how brain measurements vary across these strengths. The goal is to establish standard reference data that could help improve the accuracy of brain imaging in both clinical and research settings. Participants must be healthy adults aged 16 to 66 with no major neurological or psychiatric conditions.

What this could mean

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

Active substance
Multi-field-strength brain MRI (0.55T, 1.5T, 3T, 5T, 7T)
What this could lead to
If successful, this could create a standardized reference for healthy Chinese brains, improving the accuracy of MRI-based diagnosis and research across different scanner strengths.
What could go wrong
This is an observational imaging study, not a treatment trial. Results may not generalize beyond the specific population, and differences across field strengths could be complex to interpret.

Study facts

What this study's own registry entry says, in plain language.

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 500 people

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

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: * Aged 16 to 66 years. Voluntarily participates in the study and provides written informed consent. No contraindications to MRI examination and able to cooperate with and complete the MRI examinations. Female participants must not be pregnant. No current or previous clinical diagnosis of severe neurological or psychiatric disorders, such as schizophrenia, dementia, epilepsy, or severe sequelae of traumatic brain injury. No obvious intracranial lesions or structural abnormalities identified on routine MRI examination. Exclusion Criteria: * Presence of contraindications to MRI examination, including MRI-incompatible implanted metallic or electronic devices, cochlear implants, cardiac pacemakers, intracranial metallic clips, or similar devices. Severe claustrophobia preventing completion of the MRI examination. Pregnancy. Current or previous clinical diagnosis of severe neurological or psychiatric disorders. History of severe head trauma, brain tumor, stroke, brain surgery, or other conditions that may substantially affect brain structure or function. MRI data of insufficient quality for analysis due to marked discomfort, excessive head motion, or other causes during the examination.
