高频超声、弹性成像联合超声造影对甲状腺实性结节的诊断价值

Diagnosis of thyroid solid nodules by high-frequency ultrasonic, elastography and ultrasound contrast

摘要:

目的  探讨高频超声、超声弹性成像分级联合超声造影对甲状腺实性结节的诊断价值。方法  收治的198例患者中238个甲状腺实性结节，其中门诊接受常规超声、弹性成像两种方法联合检查（A组）诊断为恶性结节156个，接受常规超声、弹性成像及超声造影3种方法联合检查（B组）诊断为恶性结节82个，所有患者住院后经手术治疗和病理检查。结果  A组经手术病理证实为恶性的实性结节98个，B组经手术病理证实为恶性的实性结节68个，两种方法经统计学比较，差异有统计学意义（P <0.05）。结论  甲状腺结节的高频超声图像特征及超声弹性成像对甲状腺实性结节的良、恶性鉴别具有重要价值，若能联合超声造影，对甲状腺实性结节的诊断准确率会有进一步的提高。

Abstract:

Objective To investigate the value of high-frequency ultrasonic, elastography and ultrasound contrast in diagnosis of thyroid solid nodules. Methods Among the 238 thyroid solid nodules of 198 patients, 156 thyroid solid nodules were diagnosed as malignant nodules by combined high-frequency ultrasonic and elasto-graphy (group A), and 82 by combined high-frequency ultrasonic, elastography and ultrasound contrast (group B). All the patients received surgery and pathological examinations. Results Pathology confirmed 98 thyroid solid nodules were malignant in the group A, 68 thyroid solid nodules were malignant in the group B. Two groups showed significant difference (P < 005). Conclusions The high-frequency ultrasonic and elastography images of the thyroid nodules are important in differentiating benign nodules from malignant ones. In combination with ultrasound contrast, the diagnosis accuracy of thyroid solid nodules can be further improved.
