Pollock.Īnd with no hospital stay and minimal side effects, it's a procedure that is efficient and can be lifesaving. "The mechanical accuracy of the device is measured as a fraction of a millimeter," says Dr. Using 3D imaging - typically an MRI - as a guide, the gamma knife is targeted directly at the tumor. The patient's head is held still during the procedure with a headframe, which also serves as a map for the radiation. ![]() "We're performing an outpatient-based procedure that doesn't require an incision and has no risks of infections," says Dr. It's been used at Mayo Clinic for 30 years as an alternative to open brain surgery. Bruce Pollock, a Mayo Clinic neurologic surgeon. "Gamma knife radiosurgery is the precise delivery of radiation to some imaging-defined target so we're able to treat benign or malignant tumors within the brain," says Dr. It's called gamma knife surgery, but there's no cutting involved. Please "Courtesy: Mayo Clinic News Network." Read the script. The MRI technologist will talk to you throughout your exam and will give you simple instructions regarding holding your breath or holding still.Journalists: Broadcast-quality video pkg (0:59) is in the downloads at the end of the post. ![]() The coil functions as a receiver and helps the MRI system take pictures. It also allows the MRI staff to monitor your heart during the exam.Ī soft padded coil will be placed at the area where the pictures will be taken. The ECG permits the MRI machine to take pictures while your heart is beating. Depending on the type of exam, an IV (small plastic tube) may be inserted into a vein in your arm so that a contrast agent called “gadolinium” can be given to make certain parts of the heart show up better.Įlectrodes (sticky pads) will then be placed on your chest, and you’ll be attached to an electrocardiogram machine (ECG). You’ll be placed on a padded table and positioned for your exam. Learn more about safety during your MRI.Ī cardiac MRI is similar to other types of MRIs. Because MRI imaging uses a very strong magnet, it’s important for you to advise the MRI staff if you have any metal embedded in your body, including a pacemaker or implanted defibrillator. ![]() Prior to a cardiac MRI, you will be asked to complete a standard MRI screening questionnaire to ensure you’re able to safely enter the MRI area. Doctors performing a cardiac MRI are specially trained to use MRI technology for capturing three-dimensional (3-D) videos of the heart, allowing the highest level of detail in evaluating heart structure and function.Ī wide variety of disorders can be evaluated with cardiac MRI, such as: Read Less Expand All Collapse AllĪlso known as a heart MRI, cardiac magnetic resonance imaging creates detailed images of the heart. The software provides quantitative measurements that are interpreted by radiologists, which helps surgeons and other clinicians design a treatment plan. Scripps radiologists have access to advanced software technology, which helps double check the process of detecting and localizing lesions within breast tissue. People with a family history of breast cancer, and people who are known or likely carriers of the BRCA (“breast cancer”) gene, are potential candidates for breast MRI. MRI scans are playing a larger role in the detection of breast cancer in very high-risk patients. Evaluate the integrity of breast implants.Differentiate scar tissue from cancer recurrence.Monitor response to therapy in breast cancer patients.Detect breast cancer in women who may have difficulty with mammograms or other imaging techniques due to breast implants, prior surgery or dense breast tissue.Screen for breast cancer and abnormalities in high-risk patients.A breast MRI provides a more comprehensive picture than other imaging techniques.
