Clinical trial: PET-CT vs. Integrated MR-PET Scanning of GYN Cancers

Summary: This research study is an imaging pilot study. Imaging pilot studies explore the potential benefit of one imaging approach compared to another clinically accepted approach. Such studies serve to understand how feasible an approach may be and whether it is worth pursuing in formal and larger clinical trials. Researchers of this study believe that simultaneous Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) imaging will offer additional imaging information to improve cancer detection.
  MRI and PET are two tests that allow us to take pictures of the body and "look inside" the body without surgery. The MRI scanner uses a powerful magnet to make a picture of the body. The PET scanner makes pictures by using special dyes that "light up" inside the body. PET scans use radiation, similar to the radiation in a standard x-ray. We routinely use both tests to diagnose various types of cancer. As of now, the combination of PET and computed tomography (CT) has been considered a standard of care imaging approach for various cancers.
  Until recently, MRI and PET tests were done separately. Now there is a new type of test called MR-PET that combines both MRI and PET test results. This scanner uses both MRI and PET tests at the same time. We would like to find out if the MR-PET scanner can produce better and clearer images (pictures) of tumors and information about them inside of the body.
  This new MR-PET scanner is approved by the US FDA. However, some of the computer programs that tell the machine how to acquire and combine the test results are new and experimental. Experimental means that some of the computer programs are not approved by the FDA. This means that they can only be used in research studies. The MR-PET scanner has been previously used in a few human participants.

Detailed description: If you agree to participate in this study you will be asked to undergo some tests and procedures to confirm that you are eligible. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out that you do not take part in the research study. If you have had some of these tests or procedures recently, they may or may not have to be repeated. These tests and procedures include a medical history, blood tests and a urine pregnancy test. If these tests show that you are eligible to participate in the research study, you will be able to undergo a one time MR/PET imaging session on the same day you are scheduled for a PET/CT. If you do not meet the eligibility criteria, you will not be able to participate in this research study.
  We will verify that your doctor has ordered a standard PET/CT scan as part of your regular medical care. You will have that PET/CT scan at teh main MGH Boston campus. As part of the PET/CT scan, you will have an injection of a radioactive material into your vein. The radioactive material consists of glucose (sugar) that has been labeled as radioactive. Your own doctor, the radiologist performing imaging and/or the PET/CT staff will explain this type of scan to you in more detail. You will be asked to sign a separate consent form for that PET/CT scan.
  PET/CT scanning can make pictures of structures inside the body because the injected radioactive material "lights up" on the pictures. This shows us details of organs, tissues, blood vessels, and other structures in your body. The radioactive material breaks down and leaves your body gradually through the urine. It takes about a day for the radioactive material to exit your body completely. You will not receive an additional injection of radioactive material for this MR-PET study.
  You will have the standard PET/CT procedures and the study MR-PET scans on the same day. After you have the PET/CT scan, you will travel to the MGH Charlestown facility for the study MR-PET scan. It takes about 15 minutes to travel between the main MGH campus and the MGH Charlestown facility. Although you must fast (no eating or drinking) before the PET/CT scan, you do not have to fast before the MR-PET scan. You will be able to have a snack before the scan, if you wish.
  During the MR-PET Procedure: We will ask you some standard questions to make sure that you can safely have an MRI. It is important that you take off anything that contains metal, such as jewelry, piercings or zippers. You may need to put on a hospital gown. We will also ask you to empty your bladder before the scan.
  We will ask you to lie down on a narrow table. The table will slide you into the center of the very large MRI scanner, which is shaped like a tunnel. The tunnel is a little wider than your body. You will need to lie very still during the scanning process.
  In order to help hold your head still, we may place foam pillows under and around your head. The scanner makes loud banging and beeping noises when making pictures, so we will give you earplugs or headphones to protect your ears.
  The top and sides of the tunnel will be close to your face and body, which can make some people uncomfortable. If you have ever experienced a fear of small spaces (claustrophobia), please tell the MRI staff. You will be able to hear and speak to the research staff at all times during the scan. We can stop the scan at any time, if needed.
  First, we will make some pictures of your brain and/or whole body.
  The PET scan will take place at the same time as the MRI scan using our new MR-PET scanner. You will not need another injection of radioactive material for our MR-PET scan.
  During scanning, we may ask you to do some activities with your hands, look at pictures, listen to some sounds, or do other things. We will make pictures of your brain during these activities to test different settings on the scanner.
  After your study scans are complete, your time in the study will be over. The whole testing session will take up to one and a half hours. You may feel a little bit tired afterwards, so you can rest a bit before leaving the scanning area.
  You will be in this research study for about up to one month-this includes the waiting period until pathology results from the surgery are back. Your actual participation in the study will only involve that one day when you receive both the PET/CT and PET/MR.
