Insights
Dual energy CT can measure thyroid iodine content, correlating with thyroid function. This method helps assess iodine nutritional status and thyroid health, aiding disease diagnosis and treatment.
Area of Science:
- Radiology
- Endocrinology
- Nuclear Medicine
Background:
- Assessing thyroid function and iodine status is crucial for diagnosing and managing thyroid diseases.
- Dual-energy CT (DECT) offers a non-invasive method to quantify iodine concentration within thyroid tissue.
- Understanding the relationship between DECT-measured iodine and thyroid hormone levels is essential for clinical application.
Purpose of the Study:
- To investigate the correlation between dual energy CT (DECT) measured iodine concentration and total iodine content in the thyroid.
- To examine the relationship between these DECT-derived iodine metrics and blood-measured thyroid parameters.
Main Methods:
- A retrospective study included 43 patients with normal thyroid function.
- DECT scans of the neck were performed to measure mean iodine concentration and thyroid tissue volume.
- Total iodine content was calculated, and correlations with thyroid hormones (FT3, TT3, TT4, FT4, TSH) were analyzed.
Main Results:
- Total thyroid iodine content showed a positive correlation with triiodothyronine (FT3) and a negative correlation with thyroid-stimulating hormone (TSH).
- Mean iodine concentration in the thyroid was positively correlated with both FT3 and total triiodothyronine (TT3).
Conclusions:
- DECT-measured thyroid iodine content can serve as an indicator of iodine nutritional status.
- This imaging technique can aid in evaluating thyroid function and facilitate the diagnosis and treatment of thyroid diseases.
Background:
The aim of this study was to investigate the correlation of the dual energy CT measured iodine concentration and total iodine content with blood measured thyroid parameters.
Methods:
Forty-three patients with normal thyroid function at our hospital from August 2017 to October 2019 were included in this retrospective study. Dual energy CT was used to scan the neck of thyroid patients. The mean iodine concentration and thyroid tissue volume were measured to calculate the total iodine content of the thyroid. Relevant tests of triiodothyronine (FT3), total triiodothyronine (TT3), total thyroxine (TT4), free thyroxine (FT4), and thyroid hormone (TSH) were conducted. The correlation of the thyroid mean iodine concentration and total iodine content with blood-measured thyroid function was analysed.
Result:
The total iodine content in the thyroid was positively correlated with FT3 but negatively correlated with TSH. The mean iodine concentration of the thyroid was positively correlated with both FT3 and TT3.
Conclusion:
The thyroid iodine content measured by dual energy CT can be used to determine the human iodine nutritional status and evaluate thyroid function, which will facilitate the diagnosis and treatment of thyroid diseases.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

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...
