Do all forms of radiology use ionizing radiation?
Ionizing radiation refers to energy which, when absorbed by matter, creates electrically charged particles, or ions. These ions have the ability to change or mutate the cellular makeup of their surrounding environment. Not all types of diagnostic tests use this type of energy. Ultrasounds, also known as sonograms, use high frequency sound waves while MRI uses magnetic fields and radiofrequency electromagnetic radiation. These are non-ionizing forms of energy. Radiologists are trained to use the least amount of ionizing radiation possible and current methods of testing use low doses. Pregnant women or women who think they may be pregnant should consult their physician before undergoing a diagnostic exam using this type of radiation energy. • What is an open MRI? Can I request an open MRI? An open MRI has a weaker magnetic field than a regular MRI, but the tunnel in which the patient lies while being scanned is much larger so the patient is less likely to feel claustrophobic.
