Can wearing metal during CT cause significant error?

Resolved Question:

My question is whether wearing metal in my mouth during a CT angiogram could cause a significant error in the results.

I'm a 71 year old male, physically and mentally active, and living a healthy lifestyle. I work full time at home as a self-employed writer and virtual world builder. I hike, run trails, mountain bike, and dance in traditional Native American ceremonies.

In 2011, a CT angiogram showed I had an astronomical calcification score of 2271. This came as a shock to me because I've always exercised, have eaten reasonably, and have no cardiac problems in my family other than my mother's stroke at 89. and little I know of in extended family (our susceptibility is instead to cancer).

One reason I question the result is that when I read descriptions of the exam in most hospitals, patients are always told to remove all jewellery and metal. I was not told this. I wasn't wearing jewelry, but I was wearing a denture that's all metal except for the teeth. It's large and heavy.

After getting the results, my cardiologist insisted that a cardiac catheterization needed to be performed, but I was resistant to any invasive procedures. After several weeks of back and forth between us, she very reluctantly consented to perform a exercise stress echocardiogram instead. I passed this test with flying colors. In fact it's the only medical test I've ever enjoyed - I love running!

However my cardiologist said that it did not alter the fact that I have severe arteriosclerosis, as demonstrated by the CT angiogram.

I live a healthy life regardless of it. I exercise regularly, frequently very hard, and I eat healthfully - lots of fresh fruits and vegetables, whole grains, fiber, few processed foods, low saturated fats, salmon 3-4 times every week.

I feel like I have a sword hanging over my head with this arteriosclerosis.

Could my wearing an all metal denture have caused such a high calcification score in my CT angiogram results? Are there any non-invasive, non-radiation tests that could confirm or regute it? With my family susceptibility to cancer, I'm reluctant to expose myself to any more radiation, particularly because I need a lot of dental work and will be getting x-rays there also.

Thank you,

Erik Bainbridge

Hello,
Thank you for your query at DoctorSpring.com
The answer to your question is NO ... wearing metallic dental fillings etc will NOT affect your CT angiogram atherosclerotic calcification ..
Your reports are really good for your age & you have been following a good health regime too .But that has NOTHING to do with calcific atherosclerosis which is a part of aging & very common at your age & depends on genetic & race etc .....its NOT a fault in your lifestyle ..Please continue with your healthy habits..

Best wishes
