CT纹理技术及目标基因检测鉴别甲状腺结节良恶性的可行性分析

目的探讨甲状腺良恶性结节实施CT纹理技术及目标基因鉴别检测的可行性。方法对本院20例甲状腺结节患者(2019年1月到2019年6月间)均实施CT纹理技术及目标基因表达分析,分析诊断结果。结果恶性结节中熵值与良性结节对比更高(P<0.05)。CT纹理分析及目标基因联合诊断对甲状腺结节诊断敏感性、特异性、准确性最高,分别为90.0%、94.4%、92.9%。结论甲状腺良恶性结节实施CT纹理技术及目标基因联合诊断效果更好。

A stochastic discrete model of tissue and its ultrasonic backscattering coefficient

The discrete scatterer model is improved to take into account the random distribution of the size and the acoustic impedance of scatterers. The backscattering coefficient and its dependence on the frequency are calculated and analyzed. An experiment with a liver mimic phantom is conducted to verify the theoretical model.
