RT Journal Article SR Electronic T1 Thyroid Scintigraphy and SPECT/CT in a Rare Case of Dual Ectopic Thyroid JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 375 OP 376 DO 10.2967/jnmt.122.264508 VO 50 IS 4 A1 Jain, Sanchay A1 Jain, Suruchi A1 Singh, Deepa YR 2022 UL http://tech.snmjournals.org/content/50/4/375.abstract AB A dual ectopic thyroid, a rare disorder occurring as a result of aberrant embryonic development, is characterized by the simultaneous presence of thyroid tissue at 2 ectopic sites. 99mTc-pertechnetate thyroid scintigraphy remains the gold standard in confirming ectopic thyroid tissue. This case highlights the importance of thyroid scintigraphy and SPECT/CT in the evaluation of ectopic thyroid tissue and a dual ectopic thyroid that manifested during the patient’s pregnancy.
