Diagnostic Radiologists use a variety of imaging procedures to see inside the body and assess or diagnose the patient’s condition. They interpret and report on the resulting images, recommending treatment and, only when appropriate, additional tests.
Interventional Radiologists are medical doctors who diagnose and treat patients using image-guided, minimally invasive techniques such as X-rays and MRI. They carefully guide instruments through tiny incisions in the body, reaching the source of a medical problem and delivering targeted treatments.
Radiation Oncologists are doctors who prescribe and oversee each cancer patient's treatment plan. They use radiation therapy to treat cancer, and they monitor the patient's progress and adjust treatment to make sure patients receive appropriate quality care.
Medical Physicists are uniquely trained scientists working in clinical practice to ensure accuracy, safety and quality in the use of radiation in medical procedures such as medical imaging and radiation therapy.
Nuclear Medicine Physicians are highly trained specialists who use small amounts of radioactive materials to diagnose and treat cancer and other types of disease.
Radiology residents and fellows are automatically members of ACR during their training years and enjoy the many benefits of membership.
Medical Students are welcome to become ACR members (with complimentary membership) to learn more about the specialty of radiology and radiation oncology and its central role in team-based patient care.
As an ACR member, you get all the support and resources you need to create the best outcomes for you, your patients and the profession.
