Treatment Response Assessment Maps to Delineate Necrosis From Tumor After Stereotactic Radiation in Brain Metastases
What this study is about
This research study is investigating the value of an imaging study of the brain called an MRI (which stands for magnetic resonance imaging), utilized in unique way, to delineate whether the tumor has recurred or whether radiation changes have occurred after a brain metastasis treated with focused radiation has enlarged.

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
- Participants must have a histologically or cytologically confirmed solid malignancy of extracranial origin and radiographic evidence of at least one brain metastasis for which stereotactic radiation was utilized in the past. Patients with intracranial pathologic confirmation of a malignancy which originated extracranially but for which extracranial disease has not been biopsied are eligible.
- Participants must have an enlarging lesion in the brain at least 4 months after prior stereotactic radiation to the same site for which neurosurgical resection is planned as routine standard of care.
- Participants must be age 18 years or older.
- Participants must be willing to undergo study procedures.
- The effects of gadolinium / other MRI-based contrast agents on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately.
- Participants must possess the ability to understand and the willingness to sign a written informed consent document via ink on paper or via an electronic signature medium such as Adobe Sign.
Exclusion criteria
- Participants who have a contraindication to MRI (e.g. non compatible implanted metallic device for which MRI is absolutely contraindicated).
- Participants who have chronic kidney disease stage IV-V or end stage renal disease.
- Participants with a history of anaphylactic reactions to gadolinium.
- Pregnant women are excluded from this study because gadolinium-based agents have not been proven to be safe to administer to a developing fetus. Similarly, breastfeeding women will be excluded from this study.
Where
- Boston, Massachusetts
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.
