Is a CT scan worth the risk?
Know that the chances of getting cancer from a CT scan are very low. And for many people, the test is worth the small risk of radiation exposure. It can help doctors spot dangerous health problems and check that treatment works.
How many CT scans are safe in a year?
The American College of Radiology recommends limiting lifetime diagnostic radiation exposure to 100 mSv. That is equal to 10,000 chest x-rays, or up to 25 chest CTs. In the course of treatment for various chronic diseases, including cancer, you could accumulate enough CTs to approach the 100 mSv limit.

Which is better CT scan or MRI?
Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to CT images.
What does a CT scan show that an MRI does not?
Both MRIs and CT scans can view internal body structures. However, a CT scan is faster and can provide pictures of tissues, organs, and skeletal structure. An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body. MRIs are more detailed in their images.
