【摘要】：目的探讨64层螺旋CT对甲状腺良恶性结节的扫描影像特点及鉴别价值。方法回顾性分析确诊50例甲状腺结节样病变患者临床及64层螺旋CT影像资料,观察比较不同性质(良性与恶性)甲状腺结节影像表现(直径、数目、形态、边界、钙化等),同时以病理结果为标准,分析64层螺旋CT对甲状腺结节性质的诊断敏感性、特异度及准确度。结果病理证实恶性结节20例,良性结节30例;甲状腺恶性结节单发、不规则、边界模糊、砂粒样钙化、邻近结构侵犯分别占80.00%、70.00%、75.00%、55.00%、55.00%,均显著高于良性结节的33.33%、26.67%、26.67%、20.00%、0.00%,差异有统计学意义(P0.05);甲状腺恶良性结节直径、囊变、密度大小比较差异无统计学意义(P0.05)。MSCT对甲状腺恶性结节诊断敏感度、特异度、准确度分别为85.00%、90.00%、88.00%。结论 64层螺旋CT检查通过结节数目、形态、边界、邻近结构侵犯与否等征象显示有利于甲状腺结节良恶性鉴别。
[Abstract]:Objective to investigate the imaging features and differential value of 64-slice spiral CT in benign and malignant thyroid nodules. Methods the clinical and 64-slice spiral CT images of 50 patients with thyroid nodular lesions were retrospectively analyzed, and the imaging features (diameter, number, shape, boundary) of thyroid nodules of different nature (benign and malignant) were observed and compared. The sensitivity, specificity and accuracy of 64-slice spiral CT in the diagnosis of thyroid nodule were analyzed. Results 20 cases of malignant nodules and 30 cases of benign nodules were confirmed by pathology. The adjacent structure invasion accounted for 80.0075.00 and 55.00, which were significantly higher than that of the benign nodule 33.3326.67 and 26.670.000.The difference was statistically significant (P0.05A); there was no significant difference in the diameter, cystic degeneration and density of the benign thyroid nodule (P 0.05N); the sensitivity and specificity of MSCT in the diagnosis of thyroid malignant nodules. The accuracy was 85.00, 90.00and 88.00, respectively. Conclusion 64-slice spiral CT examination is helpful to distinguish benign and malignant thyroid nodules from benign and malignant ones by means of the number, shape, boundary and adjacent structure of thyroid nodules.
