In brief: 2 weeks
A low-iodine diet should usually be followed for 2 weeks prior to a thyroid whole-body scan.
The rationale behind this is to reduce the chances of non-radiactive iodine (in food and table salt) to compete with the radioactive active iodine use for diagnosis (i-123) and treatment (i-131).
