Mayo Clinic's approach
Collaboration
Mayo Clinic is one of the largest radiology practices in the world. Mayo Clinic doctors trained in medical imaging (radiologists) work closely with other medical and surgical specialists to make sure you get the care you need based on your brain CT results. Your care team may include specialists in a variety of areas, including the brain (neurology), brain surgery (neurosurgery), ear, nose and throat (otolaryngology), and cancer (oncology).
Expertise
Mayo Clinic has more than 400 skilled radiologists and physicists across campuses in Arizona, Florida and Minnesota and at Mayo Clinic Health System locations who provide imaging services.
These specialists work alongside technologists to provide imaging results quickly. Appointments are coordinated to offer a seamless care plan. What might take weeks or even months to accomplish elsewhere can typically be done in a matter of days at Mayo Clinic.
State-of-the-art technology
Mayo Clinic radiologists use advanced imaging technology, which is key to ensuring an accurate diagnosis to guide treatment. Many of these innovative imaging methods are available at very few medical centers. In recent years, Mayo Clinic installed a dual-source photon-counting CT scanner at its campus in Rochester, Minnesota — the first in North America approved for clinical use.
Photon-counting CT scanners have many advantages over standard CT technology, such as the ability to see very fine details and lower radiation doses. Additional photon-counting CT scanners are planned for other Mayo campuses.
Decades ago, Mayo Clinic was one of the first medical practices to offer CT exams to patients. Today, with at least 60 CT scanners and more than a dozen PET-CT scanners across Mayo Clinic's campuses and Mayo Clinic Health System locations, the Department of Radiology continues its leadership role in the use of advanced medical imaging to see, understand, treat and prevent disease.
Innovation
Mayo Clinic evaluates and brings into clinical use the latest CT scanner technology. Using tools such as the artificial intelligence (AI) program DIAMOND, images are made much clearer, resulting in scans that are easier to read and interpret. Dual CT scans also are helping Mayo Clinic radiologists better differentiate between two materials that traditionally appear similar, such as bone and calcium deposits.
Despite the tremendous medical benefits of CT imaging, concerns remain about the potential for negative long-term effects due to radiation exposure. To address these concerns, a Mayo Clinic team continues to develop and test dose-reduction technologies to limit radiation exposure.
Expertise and rankings
Mayo Clinic's highly specialized radiology teams perform and interpret a large number of scans each year. When integrated with ongoing research and education, this results in broad expertise in the imaging and treatment of diseases affecting people of all ages.
Mayo Clinic in Rochester, Minnesota, Mayo Clinic in Jacksonville, Florida, and Mayo Clinic in Phoenix/Scottsdale, Arizona, are ranked among the Best Hospitals for cancer by U.S. News & World Report.
Locations, travel and lodging
