甲状腺癌的超声影像学诊断与病理学对照研究

目的将甲状腺癌超声诊断结果与病理学诊断结果进行对比，研究超声诊断的符合率，探讨超声影像学诊断的优点和用于甲状腺癌诊断的临床价值。 方法回顾性分析2011年至2015年收诊的102例甲状腺疾病患者的临床资料。患者均进行超声检查和病理学检查，研究超声影像学诊断的甲状腺癌检出率及各类型甲状腺癌的符合率，采用SPSS17.0软件分析。超声诊断与病理学诊断的符合率、误诊率计数资料以百分比(%)表示，采用χ²检验进行组间比较，以P<0.05为差异有统计学意义。 结果102例患者中有83例甲状腺癌患者，超声影像学诊断与病理诊断的符合率为91.6%(76/83)，误诊率为8.4%(7/83)。其中乳头状癌、滤泡状癌和髓样癌诊断符合率分别为92.3%(60/65)、92.3%(12/13)和80.0%(4/5)。比较甲状腺良恶性肿块边缘、回声、微钙化、纵横比等声像图特征以及血流分级情况，均存在明显差异，均有统计学意义(P<0.05)。 结论超声影像学诊断在检验甲状腺癌、分辨良恶性肿瘤方面具有快速无创等优点，检出率较高，在临床上具有重要意义。

Diagnostic Method of Ultrasonic and Pathology for Thyroid Carcinoma: A comparative Study

ObjectiveTo compare the results of ultrasound diagnosis with pathological diagnosis for thyroid carcinoma, and discuss the coincidence rate of ultrasound diagnosis, to explore the advantages of ultrasound imaging diagnosis and the clinical value on the diagnosis of thyroid cancer. MethodsFrom 2011 to 2015, the clinical data of 102 patients with thyroid diseases admitted in our hospital were retrospectively analyzed. All the patients with thyroid diseases were examined by ultrasonography and pathological respectively, and the detection rate of thyroid cancer diagnosed by ultrasound imaging and the coincidence rate of all types of thyroid cancer were investigated. The SPSS17.0 software was used to analyze. The coincidence rate and misdiagnosis rate of ultrasonic and pathological were expressed in percentage (%), and compared by chi square test , the difference was statistically significant when P<0.05. ResultsAmong the 102 patients, 83 cases were diagnosed as thyroid cancer. The coincidence rate of ultrasound and pathological were 91.6% (76/83), and the misdiagnosis rate was 8.4% (7/83). Among them, there were 60 cases of papillary carcinoma, 12 cases of follicular carcinoma, 4 cases of medullary carcinoma respectively, and the diagnostic accordance rates were 92.3%, 92.3% and 80% respectively. Between the benign and malignant thyroid masses , there were significant differences in the characteristics of the edge, echo, microcalcification, longitudinal and transverse ratio, and the classification of blood flow (P<0.05). ConclusionsThe diagnosis of ultrasound imaging has the advantages of rapid and non-invasive in detecting thyroid carcinoma and distinguishing benign and malignant tumors.
