US. Health-Care providers are pledging to stop overuse of radiation on patients during examinations, launched in Chicago recently. Too much radiation can cause cancer.
Because of increased use of radiation in recent decades, particularly on new imaging and CT scans, questions were raised about possible increased cancer risk.
Addressing an imaging safety panel at Radiological Society of North America, William Hendee said "There are lots of reasons that medical images are over-utilised".
Patients can be part of the problem if they request a test they don't need because a friend had similar symptoms and got that test.
Duplicate test can also be done when a doctor doesn't know the patient's full medical record, Hendee said.
Another danger is "dose creep" when technologists increase radiation dose to get amazing-looking pictures.
"But you don't need pretty images to provide information necessary to yield a diagnosis" Hendee concluded. Acknowledgment: aolhealth.com Geoff.
