多层螺旋CT与彩色多普勒超声在诊断宫颈癌淋巴结转移中的临床价值分析

The clinical value of multislice spiral CT and Color Doppler ultrasound in the diagnosis of cervical cancer lymph node metastasis

目的 分析多层螺旋CT与彩色多普勒超声在诊断宫颈癌淋巴结转移中的临床价值。方法 选取50例宫颈癌淋巴结转移患者,分别应用彩色多普勒超声检查、多层螺旋CT检查,以手术病理诊断结果为金标准。比较彩色多普勒超声、多层螺旋CT的诊断结果,诊断准确率、敏感性及特异性。结果 50例宫颈癌淋巴结转移患者中,经彩色多普勒超声诊断出阳性14例,假阴性9例,阴性16例,假阳性11例。多层螺旋CT诊断出阳性21例,假阴性2例,阴性23例,假阳性4例。多层螺旋CT诊断的准确率、敏感性及特异性分别为88.00%(44/50)、91.30%(21/23)、85.19%(23/27),明显高于彩色多普勒超声诊断准确率、敏感性及特异性的60.00%(30/50)、60.87%(14/23)、59.26%(16/27),差异有统计学意义(P<0.05)。结论 将多层螺旋CT应用到宫颈癌淋巴结转移诊断中的价值较高,有助于提升疾病诊断的准确率,为患者诊治提供有力依据,值得推广与应用。

Objective To analyze the clinical value of multislice spiral CT and Color Doppler ultrasound in the diagnosis of cervical cancer lymph node metastasis. Methods 50 patients with cervical cancer lymph node metastasis were examined by ultrasonography and multi-slice spiral CT respectively. The diagnostic accuracy, sensitivity and specificity of Color Doppler ultrasound and multi-slice spiral CT were compared. Results Among 50 cases of cervical cancer with lymph node metastasis,14 cases were positive, 9 cases were false negative, 16 cases were negative, and 11 cases were false positive. MSCT diagnosed 21positive cases, 2 false negative cases, 23 negative cases and 4 false positive cases. The diagnostic accuracy, sensitivity and specificity of multi-slice spiral CT were 88.00%(44/50), 91.30%(21/23) and 85.19%(23/27), respectively. It was significantly higher than the diagnostic accuracy, sensitivity and specificity of Color Doppler ultrasound 60.00%(30/50), 60.87%(14/23), 59.26%(16/27), and the difference was statistically significant(P<0.05). Conclusion The application of multi-slice spiral CT in the diagnosis of lymph node metastasis of cervical cancer is of high value, which is helpful to improve the accuracy of disease diagnosis and provide a strong basis for the diagnosis and treatment of patients.
