Can MRI outshine mammograms in finding breast cancer?
NCT ID NCT01035112
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
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.

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.
