摘要
目的比较剪切波弹性成像与^(99)Tc^m-MIBI SPECT显像诊断甲状腺癌的价值。方法以118个甲状腺结节作为研究对象,行剪切波弹性成像及^(99)Tc^m-MIBI SPECT显像。以病理为金标准,计算并比较两种方法对甲状腺癌结节的诊断敏感度(灵敏度)、特异度、准确度、阳性预测值及阴性预测值,并进行率的比较。结果剪切波弹性成像与^(99)Tc^m-MIBI SPECT显像诊断甲状腺癌的敏感度(灵敏度)、特异度、准确率、阳性预测值及阴性预测值分别为88.57%(31/35)和62.86%(22/35)、89.16%(74/83)和65.06%(54/83)、88.98%(105/118)和64.41%(76/118)、77.50%(31/40)和43.14%(22/51)、94.87%(74/78)和80.60%(54/67),差异均有统计学意义(P<0.05)。结论剪切波弹性成像对甲状腺癌的诊断效能优于^(99)Tc^m-MIBI SPECT显像。
Objective To compare the diagnostic value of shear wave elastography and 99Tcm-MIBI SPECT in diagnosis of thyroid cancer. Methods Totally 118 thyroid nodules had enrolled, which were checked by shear wave elastography and 99Tcm-MIBI SPECT imaging. Taking pathology as gold standard, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value in diagnosis of thyroid nodules were calculated and compared. Results The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of shear wave elastography and 99Tcm-MIBI SPECT imaging in diagnosis of thyroid cancer were 88.57% （31/35） and 62.86% （22/35）, 89.16% （74/83） and 65.06% （54/83）, 88.98% （105/118） and 64.41% （76/118）, 77.50% （31/40） and 43.14% （22/51）, 94.87% （74/78） and 80.60% （54/67）, which had statistical difference between both methods （all P〈0.05）. Conclusion The diagnostic value of shear wave elastography of thyroid cancer is higher than those of 99 Tcm-MIBI SPECT imaging.
