I-131 Radioactive Dosage Standards
Hello,
I underwent a total thyroidectomy in November of 2009 and am scheduled for I-131 next week. I would like to find out what the proper dosage standards are for I-131? The pathology report revealed that I had microcarcinoma, metastasis to the lymph nodes, and BRAF +. I have tried to search medical journals and have found that the ranges for these conditions are between 100-150 and 150-200. I'm 5'2 and weigh approximately 140 lbs.
Thank you.

Usually the nuclear medicine doctor will dose based upon your update results but somewhere around 150mCi would be standard.
A great resource is "Essentials of Thyroid Cancer Management" (Amdur and Mazzaferri, Eds) - I picked up my copy on Amazon.com
The thyroid disorder forum here on MedHelp has some great resources too and many, many of us who have been through I-131 (or RAI as it is often referred to).
