You may notice that NMC no longer uses protective shields during imaging exams. Research over the last 70+ years has shown that modern imaging technology is safest and most accurate without shielding.
Why were shields used in the past?
In the 1950s, medical experts had less knowledge about how the X-ray radiation used in medical imaging affected our bodies. One concern was that the radiation might damage cells that could be passed along to future generations. Because of this concern, lead shields were often placed over patients’ bodies during imaging exams.
Why is shielding no longer recommended?
Radiation used in medical imaging has decreased more than 95% since the 1950s.
Better technology means that today’s medical imaging equipment can make high-quality images using only very small amounts of radiation.
Our organs are much less sensitive to radiation than previously thought.
This is true for patients of all ages.
Shields can cover up parts of the body that your doctor needs to see.
If this happens, then the exam may need to be
repeated.
Sometimes a shield can actually increase the amount of radiation from the exam.
X-ray equipment includes technology that makes sure just the right amount of radiation is used for the exam. Sometimes a shield can interfere with this technology, which can actually increase the amount of radiation from the exam.
