Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I had a thallium stress test and it was followed with an angiogram which showed a 40 per cent blockage in an artery. How often should I have another thallium stress test? I am concerned about the radiation from the. Test because 13 years ago I had lymphoma and was subjected to numerous cat scans with radiation.
