超声造影在甲状腺结节中的临床应用价值

THE CLINICAL VALUE OF CONTRAST-ENHANCED ULTRASOUND IN THYROID NODULES

目的：探讨超声造影在鉴别甲状腺良恶性结节中的应用价值。方法：选取2014-09～2015-03在我院接受检查的78例病人的95个甲状腺结节的超声常规图像及造影图像，进行回顾性分析，观察良恶性结节的增强均匀性、有无环形增强等特点，按照结节大小、结节内部回声分组，观察结节增强特点。结果：95个结节中，42个恶性结节，53个良性结节，良恶性结节超声造影增强均匀性、有无环形增强差异有统计学意义（P=0．000）。以≤1cm与〉1cm结节分组，良恶性结节比较差异有统计学意义（P=0．000）；以囊实性及实性结节分组，良恶性结节比较差异有统计学意义（P=0．000）。超声造影诊断甲状腺良恶性结节的敏感性为87．8％，特异性为88．8％。结论：超声造影可以显示甲状腺结节内部及周边的血流灌注情况，对于甲状腺结节良恶性的判定，具有重要的诊断价值。

Objective：To investigate the value of contrast-enhanced uhrasound in the differential diagnosis of benign and malignant thyroid nodules. Methods：There were 78 people in our hospital for tests were found to have 95 thyroid nodules, the 95 cases of solitary thyroid nodule were enrolled in this sduty from March 2014 to March2015, these solitary thyroid nodule ultrasound contrast images and con- ventional images were retrospectively analyzed, and observe enhance uniforrnity, rim enhancement. Compare grouped according to nodule diameters and nodule nature to observed nodular enhancement features. Results：In the 95 cases of nodules, these were 42 malignant nodules and 53 benign nodules Enhancement uniformity ,rim enhancement were proven with significant difference between the benign and malignant nodules （P = 0. 000 ）. Between the groups divided by diameters, the benign and malignant nodules groups were proven with significant difference （P = 0. 000 ）. Between the groups divided by nature, benign and malignant nodules groups were proven with significant difference （P = 0.000）. The sensitivity of ultrasound contrast imaging in diagnosis of benign and malignant nodules was 87.8 %, the sp around the thyroid differtial diagnosis ecificity was 88.8%. Conclusion： Ultrasound contrast can show blood nodule perfusion,. The ananlysis of enhancement characteristic is of benign and malignant thyroid solid nodules. flow in and valuable in differtial diagnosis of benign and malignant thyroid solid nodules.
