摘　　要：目的探讨甲状腺良恶性结节临床诊断中应用超声弹性成像(UE)和常规超声诊断的对照结果。方法便利选择该院2015年5月—2017年5月收治的经临床病理证实为甲状腺结节的患者60例(80个结节)作为研究对象,纳入对象有完整资料,均接受常规超声与超声弹性成像检查与诊断,将病理结果作为标准,比较常规超声与超声弹性成像诊断良性与恶性结节准确率,并分析二者诊断的影像学特点。结果超声弹性成像诊断甲状腺良性结节与恶性结节准确率均明显高于常规超声诊断(良性为96.15%vs 80.77%,χ2=5.093,P<0.05;恶性为89.28%vs 67.86%,χ2=4.673。P<0.05);常规超声诊断甲状腺良恶性结节声像图特点主要为良性结节多为规则形态(43个)、微钙化较少(10个)、RI<0.7为主(47个),而恶性结节为不规则形态(23个)、微钙化较多(23个)、RI≥0.7为主(24个),两组差异显著(χ2=31.877、29.724、45.607,P<0.05);超声弹性成像声像图特点为良性结节以1级最多(26个),其次为2级(15个),而恶性结节则多为4级(8个)与5级(19个)。结论甲状腺良恶性结节临床诊断中采取超声弹性成像技术诊断,相比常规超声诊断能取得更好的诊断准确率,同时声像图也有明显差异,可进行鉴别诊断,为临床提供不错的参考依据,值得借鉴。Objective To investigate the contrast between ultrasound elastography（UE） and conventional ultrasound in the diagnosis of benign and malignant thyroid nodules. Methods 60 patients（80 nodules） who were confirmed by clinical pathology as thyroid nodules from May 2015 to May 2017 in the hospital were selected conveniently as subjects. Subjects included complete data, all underwent conventional ultrasound and ultrasound, elastography examination and diagnosis, using pathological results as a standard, compared the accuracy of benign and malignant nodules diagnosed by conventional ultrasound and ultrasound elastography, and analyzed the imaging features of the two diagnoses. Results The accuracy of ultrasound elastography in diagnosing benign nodules and malignant nodules was significantly higher than that of routine ultrasonography（96.15% vs 80.77% for benign, χ^2=5.093; 89.28% vs. 67.86% for malignant, and χ^2=4.673, P〈0.05）; Conventional ultrasound diagnosis of benign and malignant thyroid nodules was mainly characterized by benign nodules with mostly regular morphology（43）, less microcalcification（10）, and RI0.7 dominated（47）. The malignant nodules were irregular（23）,slightly calcified（23）, and RI≥0.7（24）. The difference between the two groups was significant（χ^2=31.877, 29.724, 45.607,P〈0.05）; ultrasound elastography sonographic characteristics of benign nodules with a maximum of 1（26）, followed by 2（15）,while malignant nodules are mostly 4（8） and 5（19）. Conclusion The diagnosis of benign and malignant thyroid nodules was diagnosed by ultrasound elastography. Compared with conventional ultrasound diagnosis, better diagnostic accuracy can be achieved. At the same time, there are obvious differences in sonograms. Differential diagnosis can be performed, which provides a good reference for clinicians and worth learning from.
