目的比较结合弹性成像的改良甲状腺影像学报告及数据系统（TI- RADS)分级法与TI- RADS分级法、弹性成像评分法对甲状腺微小癌（TMC）检出率的诊断效能。方法对经手术病理证实的71例患者共117枚小结节的TI- RADS分级、弹性成像评分、结合弹性成像的改良TI- RADS分级进行比较，并与病理结果相对照，分别计算灵敏度、特异度、阳性似然比。结果TI- RADS分级法诊断TMC的灵敏度、特异度、阳性似然比分别为80.88%、71.47%、2.8；弹性成像评分法诊断TMC的灵敏度、特异度、阳性似然比分别为73.53%、65.31%、2.1；改良TI- RADS分级法诊断TMC的灵敏度、特异度、阳性似然比分别为94.12%、77.55%、4.2。改良TI- RADS分级法诊断TMC的灵敏度、特异度较高。改良TI- RADS分级法诊断TMC的灵敏度分别与TI- RADS分级法、弹性成像评分法的灵敏度比较，差异均有统计学意义（均P＜0.05）。结论改良TI- RADS分级法对TMC的诊断有重要的临床价值。

Objective To compare thyroid imaging reporting and data system(TI- RADS) classification, ultrasound e-lastography (UE) and TI- RADS combined with UE (improved TI- RADS) in diagnosis of thyroid microcarcinoma (TMC). Methods Seventy one patients with thyroid nodules underwent surgical resection and the removed 117 nodules were diagnosed histopathologically. With histopathological diagnosis as gold standard the diagnostic value of TI- RADS classification, UE score and improved TI- RADS for thyroid microcarcinoma was compared in terms of sensitivity, specific, positive likelihood ratio. Re-sults The sensitivity, specificity and positive likelihood ratio of TI- RADS in diagnosis of TMC were 80.88%, 71.47%and 2.8 re-spectively;those of UE were 73.53%, 65.31%and 2.1 respectively;and those of improved TI- RADS were 94.12%, 77.55% and 4.2 respectively (P<0.05). Conclusion Combination of TI- RADS classification with UE score has better diagnostic value for thy-roid microcarcinoma than the single method.
