摘要目的：分析彩色多普勒超声（CDUS）检查在甲状腺微小癌（TMC）诊断中的临床应用价值。方法选择97例 TMC 患者，在术前同时采用 CT 与 CDUS 对患者进行诊断，分析 CDUS 的应用价值。结果TMC 病灶共有112个，CT 确诊81个，CDUS 确诊99个，两者阳性率分别为72．32％、88．39％，两种方法诊断TMC 病灶阳性率差异有统计学意义（χ2＝9．146，P ＝0．002）；97例中淋巴转移13例，CT 诊断淋巴转移的符合率为53．85％，CDUS 为92．31％，CDUS 诊断 TMC 淋巴转移率明显优于 CT 诊断（χ2＝4．887，P ＝0．027）。结论CDUS 在 TMC 的诊断中有着重要的应用价值。

abstractsObjective To analyze the clinical value of CDUS in the diagnosis of thyroid cancer.Methods 97 patients with TMC were diagnosed by CDUS and CT,the clinical value of CDUS was evaluated.Results A total of 1 1 2 lesions TMC,CT diagnosis of 81 ,CDUS confirmed 99,the positive rates were 72.32%,88.39% respectively.In 97 cases,1 3 cases of lymph node metastasis,CT diagnosis of lymph node metastasis rate was 53.85%,CDUS of 92.31 %.CDUS in diagnosis of TMC was effective than CT diagnosis (χ2 =4.887,P =0.027).Conclusion CDUS has important value in the diagnosis of TMC.
