目的:探讨实时超声弹性成像(real-time ultrasound elastography,RTE)组织弥散定量技术在慢性淋巴细胞性甲状腺炎诊断中的应用价值。方法:对46名健康体检志愿者和42例慢性淋巴细胞性甲状腺炎(Hashimoto′s thyroiditis,HT)患者分别进行RTE检测,并行组织弥散定量分析获得弥散指数(LF index值)。结果 :健康体检志愿者组LF index值为1.217 6±0.800 0,HT组LF index值为2.466 9±0.710 0,用组间t检验方法进行数据分析,2组间LF index值的差异有统计学意义(P<0.05)。结论 :RTE能反映HT患者甲状腺组织的弹性情况,具有一定的临床应用价值。
Objective: To investigate the value of real-time ultrasound elastography (RTE) tissue diffusion quantitative technique in the diagnosis of chronic lymphocytic thyroiditis. Methods: 46 healthy volunteers and 42 patients with chronic lymphocytic thyroiditis (HT) were examined by RTE. Diffusion index (LF index) was obtained by quantitative diffusion analysis. Results: The LF index of healthy volunteers was 1.217 6 ± 0.800 0, and the LF index of HT was 2.466 9 ± 0.710 0. The data of t test were used to analyze the differences of LF index between the two groups Significance (P <0.05). Conclusion: RTE can reflect the elasticity of thyroid tissue in patients with HT and have certain clinical value.
