Comparative Performance of Molecular Breast Imaging (MBI) to Magnetic Resonance Imaging (MRI) of the Breast in Identifying and Excluding Breast Carcinoma in Women at High Risk for Breast Cancer
What this study is about
To evaluate the diagnostic performance of Tc99m sestamibi (MBI) compared to breast MRI in women who are at high risk for developing breast cancer. To assess the relationship of tumor size, histologic subtype and location of lesion and how it affects lesion conspicuity and sensitivity in MBI detected cancers.

To evaluate the diagnostic performance of Tc99m sestamibi (MBI) compared to breast MRI in women who are at high risk for developing breast cancer. To assess the relationship of tumor size, histologic subtype and location of lesion and how it affects lesion conspicuity and sensitivity in MBI detected cancers.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- The subjects to be studied will include female patients ages 18 and older of any race, identified as carrying an elevated risk for breast cancer referred to MDACC.
- High risk may be defined as having a calculated lifetime risk \>20%, histopathology of lobular neoplasia or atypical ductal hyperplasia, atypia NOS or a genetic mutation known to predispose the patient to breast cancer.
- Subject who are scheduled for a Breast MRI who are willing to participate fully in all aspects of the study including completing both a Breast MRI \& MBI screening exam within a two-week time window, a biopsy of any positive findings and complete a post examination survey. Consent for the enrollment may be obtained upon scheduling the MRI examination. For non-English speakers, a language interpreter will assist in translation.
- Written consent will be obtained from all participants to obtain MBI of the breasts and biopsy as indicated, based on findings. All participants will be asked to provide a post examination survey of their experience with both tests.
Exclusion criteria
- Subjects who are pregnant will be excluded as MBI exam involves injection of radioactive tracer
- contrast enhanced MRI involves gadolinium injection, both of which are contraindicated during pregnancy.
Where
- Houston, Texas
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
