What You Need to Know About Radiation Exposure in CT Scans

Early detection is a cornerstone of effective healthcare for men of all ages.

CT scans are a powerful diagnostic tool, but many Canadians have questions about the radiation involved and how it fits into proactive health care. 

In this blog, we’ll break down what radiation exposure from CT scans really means, how it compares to other imaging tests, and why CT scans can be an important part of a proactive health plan.

CT scans combine multiple X-ray images to create detailed pictures of your organs, bones, and tissues. Radiation exposure is measured in millisieverts (mSv), which helps quantify how much radiation your body receives.

To put it in perspective, a standard chest X-ray delivers about 0.1 mSv, equivalent to the natural background radiation you’d encounter over roughly 10 days. In comparison, an abdominal CT scan exposes you to around 10 mSv, roughly the same as three years of everyday background radiation.

While CT scans do expose you to more radiation than a simple X-ray, the detailed images they provide are essential for detecting conditions that may not be visible otherwise.

How CT Scans Fit Into Preventive Health

Preventive CT scans allow you to take a proactive approach to your health rather than waiting for symptoms to appear. They can help assess cardiovascular health through coronary calcium scoring or CT angiography, and digestive health via virtual colonography.

When combined with a physician consultation and optional lab testing, CT scans provide a more comprehensive view of your health, allowing you to make informed decisions early. This approach supports long-term wellness and early intervention when needed.

Preventive imaging can reveal early signs of potential issues and provide a clearer understanding of your internal health.
