Does thoracic spine mri safe? does it have any side effects in the future? i heard it can cause cancer thank you

MRI is safe: MRI is a safe test and it is actually safer than a CT scan which is often the alternative test that is commonly used for diagnostic tests. The main difference is that MRI doe snot expose you to radiation(which most other X-rays do). The lack of radiation makes MRI a safer test.. It does not cause Cancer....X-rays do have that risk albeit it is very small risk.

Safe: There are no known short or long term risks from MRI. Wish you good health!
