【摘要】：目的探讨多排螺旋CT在甲状腺癌临床诊断和鉴别诊断中的应用价值。方法选取西安交通大学医学院附属西安市中心医院收治的55例疑似甲状腺癌患者为研究对象,均接受多排螺旋CT检查。以外科手术或病理检查结果为依据,评估多排螺旋CT在甲状腺癌临床诊断中的敏感性、特异性和准确性,记录其在甲状腺癌鉴别诊断中的符合率。结果病理或手术检查结果显示55例疑似甲状腺癌患者中甲状腺癌32例(58.2%),良性病变23例(41.8%);多排螺旋CT扫描定性诊断结果显示真阳性28例,真阴性20例,假阳性3例,假阴性的4例;多排螺旋CT对甲状腺癌定性诊断的准确性、特异性、敏感性分别为87.3%(48/55)、87.0%(20/23)和87.5%(28/32);对乳头状癌、滤泡状癌、髓样癌及未分化癌等甲状腺癌的鉴别诊断准确率分别为94.7%(18/19)、71.4%(5/7)、66.7%(2/3)和100.0%(3/3)。结论临床可将多排螺旋CT作为诊断及鉴别诊断甲状腺癌的有效辅助手段,以提高诊疗筛查针对性,节省诊疗时间、改善患者预后水平。
[Abstract]:Objective to evaluate the value of multi-slice spiral CT in the diagnosis and differential diagnosis of thyroid carcinoma. Methods 55 patients with suspected thyroid carcinoma were selected from Xi'an Central Hospital affiliated to Xi'an Jiaotong University Medical College. The sensitivity, specificity and accuracy of multi-slice spiral CT in the clinical diagnosis of thyroid carcinoma were evaluated based on the results of surgical or pathological examination. The coincidence rate in differential diagnosis of thyroid carcinoma was recorded. Results among 55 suspected thyroid cancer patients, 32 (58.2%) were thyroid cancer, 23 (41.8%) were benign lesions, 28 were true positive, 20 were true negative and 3 were false positive. The accuracy, specificity and sensitivity of multislice spiral CT in the qualitative diagnosis of thyroid carcinoma were 87.3% (48 / 55) and 87.5% (20 / 23) and 87.5% (28 / 32), respectively, and the accuracy of differential diagnosis for papillary carcinoma, follicular carcinoma, medullary carcinoma and undifferentiated carcinoma were 94.7% (18 / 19) 71.4% (57 / 57) and 100.0% (3 / 3), respectively. Conclusion Multi-slice spiral CT can be used as an effective assistant method for diagnosis and differential diagnosis of thyroid carcinoma in order to improve the pertinence of diagnosis and treatment, save the time of diagnosis and treatment, and improve the prognosis of patients.
