LLAMAS-OLIER, Augusto  and  CADENA, Enrique. I-131 SPECT/CT in differentiated thyroid cancer. rev.colomb.cancerol. [online]. 2013, vol.17, n.3, pp.122-125. ISSN 0123-9015.

The frequency of thyroid cancer has increased over the past twenty years probably due to the use of high-resolution diagnostic studies. Treatment is based upon thyroidectomy plus radioactive iodine remnant ablation (RRA) and suppressive therapy with sodium levothyroxine, and follow-up with thyroglobulin and high-resolution ultrasound. RRA is followed by a planar whole-body scan oftentimes unable to provide exact uptake localization. Single-photon emission computed tomography/computed tomography (SPECT/CT) has emerged as an imaging complement to acquire fused images that can provide anatomic localization of radioactive sites. We used it to clarify the location of an avid lesion after administering 200 mCi of I-131 to a female patient as part of her treatment.
