Radiation Safety

Radiology is a broad field, encompassing many forms of imaging. Much of what we do involves no harmful radiation at all--ultrasonography uses ultrasonic sound waves and MRI uses powerful magnets to measure changes in the magnetic field of your body. However, radiology still relies heavily on ionizing radiation to help get a diagnosis, using x-rays in mammography, radiography and CT (computerized tomography) and using emitted x-ray radiation from radioisotopes in nuclear medicine. Your doctor, in consultation with a radiologist, will decide what kind of test is best for your particular situation.

Sometimes that will involve x-rays, and we are conscious of the risks of radiation but also diligent about reducing radiation by all means possible and about educating patients about the relatively small magnitude of the risk.

Modalities using small doses of radiation
  • Radiography (chest x-ray, bone x-rays)
  • CT scans
  • Interventional procedures using x-ray or CT guidance
  • Interventional procedures using ultrasound guidance
  • Fluoroscopy (Barium swallow or enema)
  • Nuclear medicine (bone scans, PET, PEM, thyroid or renal scans)
  • Mammography
Modalities without harmful radiation
  • Ultrasonography (vascular, gallbladder or pelvic ultrasound)
  • MRI scans
  • Interventional procedures using ultrasound guidance
  • Breast ultrasound
