Debunking Myths About Imaging: CAT Scans, X-Rays, Ultrasounds and More

Imaging includes CAT scans, X-rays, ultrasounds and more -- and imaging is an important part of your care! Tonya Viars, director of imaging services at Wesley Long Hospital, debunks myths about imaging in this 2 Your Well-Being discussion with WFMY News 2.

Let's first talk about a common myth: Radiation from X-rays, CAT scans, and other similar tests is harmful. Is that true?

"Wonderful question. Radiology has come a really long way in the past 10 years. Radiology services are now digital, which has reduced radiation doses to patients by half. So Cone Health even has a dose reduction software that monitors patient size and gives the appropriate dose for the exam that will maintain a high quality of images that we expect. Here at Cone Health, we even take it one step further with dose monitoring software that tracks the lifetime dose of our patients and monitors every Cone Health location for continuity of care to ensure the highest quality, no matter what Cone Health location the patient seeks care at."

Here's a second myth: Pregnant women should not get X-rays. Is that true?

"The possibility of X-rays during pregnancy causing harm to your unborn child is very small. Generally, the benefits of diagnostic information from the X-ray outweigh the risk potential for the baby. The best thing you can do is if you are pregnant or you think you might be pregnant is to inform your healthcare provider and the technologist that's providing those services.

Another common myth is that MRIs, CAT scans and other similar tests use radiation. Is that true?

"No, that is definitely a myth. MRIs use magnetic fields and computer generated radio waves -- not radiation at all. Ultrasounds use sound waves to produce images. So again, there's no radiation there either."

Finally, another common myth is that you don't have options for where to go to get medical imaging done. Is that true?

"That's a huge myth! So here at Cone Health, we are one team. Imaging services such as X-rays, CT, mammograms and other similar tests are available throughout Cone Health at multiple locations close to your home in both non-hospital settings, such as MedCenter High Point or MedCenter Greensboro, and of course you also have the hospital locations."

"If your doctor recommends you get one of these medical tests, talk to them about what location is convenient for you... we encourage our patients to get involved be an active part of your medical care."
