Summary
Single photon-emission computed tomography/computed tomography (SPECT/CT) precisely locates iodine uptake in the neck for pediatric papillary thyroid cancer patients. This imaging technique aids treatment decisions and improves diagnostic accuracy.
Area of Science:
- Nuclear Medicine
- Pediatric Oncology
- Radiology
Background:
- Single photon-emission computed tomography/computed tomography (SPECT/CT) enhances the localization of radiopharmaceuticals that emit single photons.
- Accurate localization is crucial for effective management of recurrent or residual disease in thyroid cancer.
Purpose of the Study:
- To evaluate the clinical utility and diagnostic value of SPECT/CT in pediatric patients diagnosed with papillary thyroid carcinoma.
- To assess the impact of SPECT/CT on treatment decisions and patient management following total thyroidectomy.
Main Methods:
- Retrospective review of 20 SPECT/CT and planar imaging studies from 13 children with papillary thyroid carcinoma post-total thyroidectomy.
- Studies utilized Iodine-123 or Iodine-131 radiotracers, with TSH elevation induced by T4 deprivation or thyrotropin alfa.
- SPECT/CT imaging was performed using either diagnostic-quality or localization-only CT units; stimulated thyroglobulin levels were analyzed.
Main Results:
- SPECT/CT precisely localized all foci of neck activity, improving upon poorly localized findings on planar imaging.
- SPECT/CT differentiated benign uptake (e.g., thyroglossal duct remnants, skin contamination) from malignant disease in six studies.
- In two cases, SPECT/CT findings supported the decision to withhold radioactive iodine treatment, demonstrating significant clinical impact.
Conclusions:
- SPECT/CT provides accurate anatomical localization of iodine uptake in the neck for pediatric papillary thyroid carcinoma patients.
- The use of SPECT/CT can influence treatment strategies and aid in the appropriate management of these patients.
- SPECT/CT is a valuable imaging tool that should be incorporated into the care of thyroid carcinoma patients when available.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
