This study aimed to determine the correlation between thyroid computed tomography (CT) density and thyroid functional status.
Thyroid CT densities were determined in patients who had a noncontrast CT of the cervical spine and a recent thyroid-stimulating hormone (TSH) measurement in a cohort of 157 patients. Thyroid CT densities of patients with abnormally low TSH and high TSH were compared to those with normal TSH. A correlation analysis was performed to determine the correlation between TSH levels and CT densities.
Both low and high TSH groups demonstrated significantly decreased thyroid CT densities (P < 0.0001). There was significant positive correlation between thyroid CT densities and TSH levels (r = 0.40; P < 0.0001) for subjects with a TSH level of less than 3.0 μIU/mL and a significant negative correlation (r = -0.66; P < 0.0001) for those with a TSH level of greater than or equal to 3.0 μIU/mL.
There is a significant correlation between thyroid CT density and serum TSH levels. A low thyroid CT density indicates abnormal thyroid function.
本研究旨在确定甲状腺计算机断层扫描(CT)密度与甲状腺功能状态之间的相关性。
在一组157例患者中,对进行过颈椎平扫CT且近期测量过促甲状腺激素(TSH)的患者测定甲状腺CT密度。将TSH异常降低和升高的患者的甲状腺CT密度与TSH正常的患者进行比较。进行相关性分析以确定TSH水平与CT密度之间的相关性。
TSH降低组和升高组的甲状腺CT密度均显著降低(P < 0.0001)。TSH水平低于3.0 μIU/mL的受试者中,甲状腺CT密度与TSH水平呈显著正相关(r = 0.40;P < 0.0001),而TSH水平大于或等于3.0 μIU/mL的受试者中,两者呈显著负相关(r = -0.66;P < 0.0001)。
甲状腺CT密度与血清TSH水平之间存在显著相关性。甲状腺CT密度降低表明甲状腺功能异常。
