目的:探讨彩色多普勒血流显像诊断甲状腺癌的临床应用价值。方法:对110例经手术后病理证实的甲状腺癌患者的术前彩色多普勒血流显像检查结果进行回顾性研究。结果:本组病例中,显示回声高低不均结节90例(81.82%),低回声的实性结节13例(11.82%),囊实混合型结节7例(6.36%),结节中检出有砂粒样钙化灶86例(78.18%)。血流成像显示Alder2级或3级的92例(83.64%),可见穿入肿块内部血管者43例(39.09%),血流为高阻力型者(RI>0.7)87例(79.09%)。结论:甲状腺癌回声表现及肿瘤结节的血流表现具有特异性,彩色多普勒血流显像诊断甲状腺癌具有重要临床意义。
Objective: To investigate the clinical value of color Doppler flow imaging in the diagnosis of thyroid cancer. Methods: The preoperative color Doppler flow imaging examination results of 110 cases of thyroid cancer confirmed by pathology were retrospectively studied. Results: In this group of patients, there were 90 cases (81.82%) with uneven echogenic nodules, 13 (11.82%) with solid hypoechoic nodules, 7 (6.36%) mixed cystic nodules, In the detection of sand-like calcification 86 cases (78.18%). Blood flow imaging showed 92 cases (83.64%) of Alder grade 2 or 3, which showed that there were 43 cases (39.09%) penetrating the internal blood vessels and 87 cases (79.09%) with high resistance blood flow (RI> 0.7). Conclusion: The echogenicity of thyroid carcinoma and the nodular blood flow of tumor are specific. The diagnosis of thyroid cancer by color Doppler flow imaging is of great clinical significance.
