NCT ID NCT01035112

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares magnetic resonance imaging (MRI) with standard diagnostic techniques like mammography to see which method best finds and defines breast cancer. Researchers will enroll about 500 women with suspicious breast lesions to evaluate accuracy. The goal is to improve early detection and reduce unnecessary biopsies.

What this could mean

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

What this could lead to
If MRI proves superior, it could become the preferred tool for detecting and mapping breast cancer, potentially reducing unnecessary biopsies.
What could go wrong
This is an observational comparison, not a treatment trial. MRI may not outperform existing methods, and results may not change current practice.

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.

Started

Apr 1995

Expected to finish

May 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

21 years and older

Sex

Female participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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 * Female * Documented breast physical examination, * Documented mammography within 3 months of the MR studies * Palpable or mammographically-detected suspect breast lesions * Women who have already undergone lumpectomy for breast cancer and have post-biopsy/post-radiation changes will be eligible if they have mammographically-detected or palpable breast abnormalities which are sufficiently suspicious to merit core needle or surgical biopsy. EXCLUSION CRITERIA: * Male by birth * Able to complete the MR examination. Subjects will be interviewed by one of the investigators for the usual contraindications to * MR contraindications including * Pacemakers * Metallic implants * Severe claustrophobia * Aneurysm clips * Pregnancy * Current lactation * Other conditions precluding proximity to a strong magnetic field. * Received an enhanced MR procedure within 48 hours, * Iodinated contrast within six hours, * Known sensitivity to MR contrast agents, * Not likely to complete the study in full or * Other clinical reason which would preclude participation in the protocol.
