There are a number of studies being conducted in the area of MRI. Research has focused on advanced MRI technology for the diagnosis and treatment of several medical conditions. Current research studies include the following areas:

• New imaging systems. The 7 Tesla MRI system is being tested in several research medical institutions in the United States. This scanning system utilizes stronger magnetic fields that show promise for higher sensitivity, speed and resolution.
  
  
• Contrast agents. Scientists continue to research the development of new contrast agents that can improve MRI. Some studies are examining the use of several contrast agents together, known as combined contrast enhanced MRI. The combined agents have been accurate in detecting liver fibrosis and liver cancers. In addition, advances with contrast-enhanced imaging has improved techniques for MRI-guided biopsies.
  
  
• MRI with heart implants. Researchers are developing methods that may allow patients with certain heart implants to undergo MRI testing. The method involves reprogramming the devices and using a lower-energy scan. It has been tested with modern implanted defibrillators and pacemakers. The U.S. Food and Drug Administration (FDA) has not authorized any implanted cardiac device for MRI testing, except in research studies.
  
  
• New computer analysis. Several researchers and technology companies have focused on developing new software programs for MRI testing. New software has shown promise for early detection and treatment of breast cancer using serial-time images.
  
  
• Treatment for uterine fibroids. Researchers are examining the effectiveness of MRI technology for the treatment of fibroids in the uterus. In this procedure, MRI images are used to help a physician utilize a technique called focused ultrasound heating that destroys the fibroids. This treatment method is also being applied to tumors of the breast.
