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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a modified MRI technique designed to reduce image distortion caused by metal hip implants. Researchers will compare standard and modified scans in 22 adults with hip replacements to see if the new method provides clearer pictures of nearby tissues. The goal is to improve diagnosis and monitoring of complications around the implant.

What this could mean

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

Active substance
Modified MRI (radiofrequency pulse polarization optimization)
What this could lead to
If successful, this could lead to clearer MRI images for people with hip replacements, helping doctors better diagnose problems around the implant.
What could go wrong
This is a very small, early-stage study with only 22 participants, so results may not apply to everyone. The modified MRI may not consistently improve image quality.

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 22 people

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

Started

Aug 2022

Expected to finish

Dec 2027

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.

Ages

18 to 99 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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

Inclusion Criteria: * Patients aged ≥ 18 with unilateral symptomatic (e.g. pain) total hip arthroplasty * Referred for MRI examination at the discretion of the treating physician * Provision of signed and dated informed consent form * No metal hardware in the body including contralateral hip arthroplasty * No contraindication to MRI: defined as claustrophobia or presence of other MRI-incompatible devices Exclusion Criteria: * History of revision hip arthroplasty * Pregnancy (self-reported, or self-suspected) * Hip arthroplasty surgery within one year of enrollment * Clinical indication to administer intravenous contrast material during MRI
