We will pick the best test for you. All are safe. If you are worried about radiation doses- don’t be.
A dose can be measured in Seiverts.
Usually we quote in milliSeiverts (mSv)
A 1000 microSeiverts makes a mSv and a 1000 mSv makes a single Seivert.
Ultrasound based tests and MRI scans have no radiation involved.
A CT calcium scan provides about 1 mSv, which is similar to the radiation from a mammogram.
A CT Coronary angiogram ranges from 2 to 7 mSv.
Nuclear medicine stress tests ranges from 4 to 10 mSv.
The average person receives about 3 millisieverts (mSv) of background radiation per year from natural sources.
