| ［摘要］ 目的 研究甲状腺病变采用超声弹性成像应变率比值法（下称比值法）的可行性。方法 选取196例患者共238个甲状腺结节，对比该研究方法与病理诊断结果的差异性。结果 病理学诊断结果显示良性结节196个，恶性结节42个。比值法诊断良性结节190个，恶性结节48个。比值法以<3.3为良性，≥3.3为恶性，诊断恶性结节特异性为85.71%，敏感性为93.88%。比值法结果与病理诊断结果比较差异无统计学意义（P>0.05）。结论 超声弹性成像应变率比值法可有效鉴别甲状腺病变状态，临床上可结合病理诊断降低误诊率。 |

| Abstract: |
| ［Abstract］ Objective To study the feasibility of ultrasound elastography strain rate ratio method in the diagnosis of thyroid lesions.Methods A total of 196 patients with 238 thyroid nodules, were selected for comparing the difference in the diagnosis of thyroid lesions between the ratio method and pathological diagnosis.Results Pathological diagnosis showed 196 benign nodules, 42 malignant nodules. The ratio method showed 190 benign nodules, 48 malignant nodules; When ratio method took <3.3 as benign, ≥3.3 as malignant, for diagnosis of malignant nodules the specificity of ratio method was 85.71%, the sensitivity was 93.88%. There was no significant statistically differences in the diagnosis results between two methods(P>0.05).Conclusion Ultrasound elastography strain rate ratio method can effectively identify thyroid lesions, clinically it can be combined with pathological diagnosis to reduce misdiagnosis rate. |
