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 value of shear wave elastography with ~(99)Tc~m-MIBI SPECT imaging in the diagnosis of thyroid cancer. Methods 118 thyroid nodules were used as study objects, shear wave elastography and ~(99)Tc~m-MIBI SPECT imaging. Using pathology as the gold standard, the diagnostic sensitivity (sensitivity), specificity, accuracy, positive predictive value, and negative predictive value of the thyroid cancer nodules by the two methods were calculated and compared, and the rates were compared. Results The sensitivity (sensitivity), specificity, accuracy, positive predictive value, and negative predictive value for the diagnosis of thyroid cancer by shear wave elastography and ~(99)Tc~m-MIBI SPECT imaging 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), the differences were statistically significant (P<0.05). Conclusions Shear wave elastography is superior to 99% Tc~m-MIBI SPECT imaging in the diagnosis of thyroid cancer.
