[Does thyroid scintigram still have indications in 2005?].

Since 15 years, the indications of thyroid scintigrams have been dramatically reduced. This examination appeared useless in most cases of hypothyroidism and for the evaluation of thyroid cysts or for infracentimetric nodules. For greater solid nodules, its poor sensibility and bad specificity have resulted in its replacement by echography and fine needle biopsy. Thyroid scintigram is however usefull for the non obvious etiologic diagnosis of thyrotoxicosis and in case of thyroid goiter with a low TSH and normal thyroid hormons. Whole body131 I scans remain usefull for thyroid cancer follow up, especially after therapeutic dose of radioiodine.
