Details and patient eligibility

About

This research study is a Pilot study (a small preliminary study to assess the feasibility of a larger, more in depth study involving a new test or procedure) and is being done to evaluate the feasibility and accuracy of PET/MRI in the evaluation of cancer. PET/MRI is a FDA approved technology that is currently being studied to assess its accuracy and utility in the diagnosis and management of a variety of diseases and patient populations. The focus of this particular study will be to compare the performance of PET/MRI in its ability to detect and characterize cancerous tumors using positron emission topography and computed tomography (PET/CT) as a reference standard.

Full description

If you agree to participate in this study you will be asked to fill out a screening questionnaire to determine if you can participate. No additional screening tests or procedures will be necessary prior to your participation in this study.

If the screening questionnaire shows that you are eligible to participate in the research study, you will be scheduled to undergo your PET/MRI in conjunction with your PET/CT. If you do not meet the eligibility criteria, you will not be able to participate in this research study.

After th screening procedures confirm that you are eligible to participate in the research study:

1. You will schedule your PET/CT examination with the MGH radiology department according to the orders and instructions of your oncologist (cancer doctor)
2. Study personnel will coordinate the scheduling of your PET/MRI examination to coincide with date and time of your PET/CT examination
3. Following the performance of your PET/CT examination you will be transported (with your accompanying family member(s)) to the Charlestown Navy Yard MGH imaging facility where you will undergo your PET/MRI examination. No additional dose of radioactive tracer (a substance which is labeled with a radioactive molecule that can be tracked within your body based on the radiation it emits) will be given as part of your PET/MRI examination
4. The PET/MRI will take up to 60 minutes to complete and after it is completed you will be free to go
5. The PET/MRI images will be interpreted by physicians (trained radiologists) as part of the study analysis; however no report of the findings will be made available to you. You will have access to the results of the PET/CT examination as you would any other clinical imaging examination.
6. If you are willing, with each subsequent PET/CT examination you undergo while enrolled in the study, you will also undergo a PET/MRI examination
7. The study will last for 12 months, after which time you will no longer be enrolled

Enrollment: 8 patients

Sex: All

Ages: 5 to 18 years old
