| 目的 评价超声弹性成像技术定性诊断甲状腺结节的价值。方法 对68例甲状腺结节患者的90个甲状腺结节进行常规超声和超声弹性成像检查,并进行硬度分级,计算病灶弹性成像图与灰阶声像图面积比值,将诊断结果与手术后病理结果进行对比。结果 甲状腺恶性结节弹性成像硬度评分高于良性结节,恶性结节弹性成像图与灰阶声像图的面积比值高于良性病灶(P均<0.05)。若以硬度分级≥4级、病灶弹性成像图与灰阶声像图面积比值≥1.48作为诊断恶性结节的标准,则弹性成像硬度分级联合面积比值诊断甲状腺恶性结节的敏感度、特异度、准确率分别为94.44%(17/18)、88.89%(64/72)、90.00%(81/90)。结论 超声弹性成像硬度分级能判断甲状腺结节的相对硬度,结合结节弹性成像图与灰阶声像图面积比值有助于鉴别诊断甲状腺结节的良恶性。 |

| Objective To assess the value of elastosonography in qualitative diagnosis of thyroid nodules. Methods A total of 68 patients with 90 thyroid nodules underwent conventional ultrasonography and elastosonography. The elastograms of 90 thyroid nodules were scored, and the area ratios of nodules on elastogram and grey-scale images were calculated. The results of the nodule scores and area ratio were compared with pathological findings. Results The elastographic scores and the area ratios of nodules on elastograms and on grey-scale images of malignant thyroid nodules were higher than those of benign ones (both P＜0.05). Taking the cut-off value of the elastographic scores ≥4 and the area ratios ≥1.48 as the diagnostic standards, the sensitivity, specificity and accuracy was 94.44% (17/18), 88.89% (64/72) and 90.00% (81/90), respectively. Conclusion The elastographic scores combined with the area ratios of nodules on elastograms and on grey-scale images are helpful in differentiating benign and malignant thyroid nodules. |
