摘要:
目的 探讨甲状腺乳头状癌采用实时超声弹性成像技术的应用价值。 方法 回顾性分析2013年9月~2014年9月入我院进行手术治疗的甲状腺乳头状癌患者、甲状腺良性结节患者各30例，所有患者术前行甲状腺超声诊断技术检查，术后经病理组织标本活检证实为甲状腺乳头状癌、甲状腺良性结节。对两组病理诊断结果、超声图像特点和实时超声弹性成像结果进行对比和分析。 结果 甲状腺乳头状癌结节内的钙化多数为微小钙化，结节边缘毛糙，结节纵横比≥1，差异具有统计学意义（P < 0.05）。乳头状癌组的结节为Ⅳ级的个数明显多于良性结节组，乳头状癌组的结节为Ⅳ级的个数明显多于良性结节组，差异均具有统计学意义（P < 0.05）。 结论 实时超声弹性成像能够准确的评价甲状腺结节的相对硬度，对鉴别甲状腺良、恶性肿瘤及甲状腺乳头状癌具有重要的应用价值。 Abstract:Objective To explore the application value of real time ultrasound imaging technique in thyroid papillary carcinoma. Methods We retrospectively analyzed thyroid papillary carcinoma patients and thyroid benign nodules of our hospital between September 2013 to September 2014, with 30 cases in each group. All the patients before thyroid ultrasound examination and postoperative pathological biopsy specimens confirmed papillary thyroid carcinoma and benign thyroid nodules. The results of pathological diagnosis, ultrasound image features and real-time ultrasound imaging results were compared and analyzed. Results Papillary carcinoma of thyroid nodule calcification most as microcalcification, nodules rough edge, nodular aspect ratio was more than or equal to 1, the difference wa statistically significant (P < 0.05). The number of nodules in the papillary carcinoma group was significantly higher than that in the benign group, and the number of nodules in the papillary carcinoma group was significantly higher than that in the benign group, and the difference was statistically significant (P < 0.05). Conclusion Real time ultrasound imaging can accurately evaluate the relative hardness of thyroid nodules, which has important application value in the differential diagnosis of benign and malignant thyroid tumors and papillary thyroid carcinoma. -
