I had a TT which showed an fully encapsulated pap carcin less than 1cm and mestatisized pap carc in 1 out pf 9 lymph nodes removed and my endo has given me the option to postpone RAI (possibly indefinately pending monitoring results - ultrasounds & thyroglobulin levels). My Endo never mentioned a PET scan. Is a pet scan the normal protocol since I have not had RAI? If so, when should I have it done?
