Answer to Question #7785 Submitted to "Ask the Experts"Category: Nuclear Medicine Patient Issues — Therapeutic Nuclear Medicine The following question was answered by an expert in the appropriate field: Q
A family member, a 36-year-old female, had thyroid surgery followed by iodine-131 therapy three years ago. Recently she had a whole-body PET (positron-emission tomography) scan, which came out clear. She wants to have a baseline mammogram done, and she would like to know how long she should wait after her PET. She is concerned with the added radiation dose/risk.
A
She needs to wait until the next day, when all the fluorine-18 has decayed away. But besides that, there is no reason to wait to have a mammogram. The radiation doses from mammograms are small and unimportant as far as risk.
