| 目的 利用能谱CT能谱成像测量成人甲状腺碘浓度的正常值及甲状腺与周边组织碘比值。 方法 采用能谱CT对226例疑颈部或颈椎疾病患者进行能谱扫描,扫描范围包括甲状腺。将所有患者分为<40岁组、40~60岁组、>60岁组。利用GSI Viewer浏览器处理,取得甲状腺组织的最佳对比噪声比对应的单能量值,在碘基图上测量双侧甲状腺、胸锁乳突肌的碘浓度并其求比值。 结果 甲状腺左、右叶碘浓度差异无统计学意义(P=0.99);男性、女性甲状腺碘浓度差异有统计学意义(P<0.01)。除40~60岁与>60岁组间差异无统计学意义外(q=0.32,P>0.05),其余各组间比较差异均有统计学意义(q=5.62、5.42,P均<0.01)。甲状腺与胸锁乳突肌碘浓度比值为96.63±33.24。 结论 宝石CT能谱成像可以准确测量甲状腺碘浓度,取得甲状腺与胸锁乳突肌碘浓度的比值,可用来评估甲状腺功能。 |

| Objective To measure the iodine concentration of normal thyroid, as well as the ratio of normal thyroid gland and surrounding tissue with gemstone spectral imaging (GSI). Methods Totally 226 patients with suspected neck or cervical disease underwent GSI of neck including the whole thyroid gland. The patients were divided into <40 group, 40-60 group and >60 group according to the ages. Then the imaging data were transmitted to AW 4.4 station to obtain monochromatic images of optimal contrast-to-noise ratio (CNR) and iodine-based images with GSI Viewer. Iodine concentration of thyroid and sternocleidomastoid muscle as well as iodine concentration ratio of thyroid to sternocleidomastoid muscle were calculated. Results No significantly statistical difference of the iodine concentration was found in the right and left thyroid lobe (P=0.99), while the difference of iodine concentration between male and female patients was statistically significant (P<0.01). There was no statistical difference between 40-60 group and >60 group (q=0.32, P>0.05), while differences between other groups were statistically significant (q=5.62, 5.42, both P<0.01). The ratio of the iodine concentration between thyroid and the sternocleidomastoid was 96.63±33.24. Conclusion It is easy to calculate thyroid iodine concentration and iodine concentration ratio of thyroid to sternocleidomastoid muscle with gemstone spectral imaging, which is helpful to the evaluation of thyroid function. |
