超声造影与彩色多普勒超声、常规超声在肝脏占位性病变诊断中的应用价值比较

Value comparision of contrast-enhanced ultrasonography, color Doppler ultrasonography and conventional ultrasonography in the diagnosis of liver space-occupying lesions

目的比较分析肝脏占位性病变的临床诊断中超声造影与彩色多普勒超声、常规超声的应用效果。方法选取2016年1月~2018年6月我院收治的78例疑似肝脏占位性病变的患者作为研究对象,经病理检查确认68例为肝脏占位性病变患者,入组患者分别接受超声造影、彩色多普勒超声和常规超声检查,将三种检查结果与活检病理检查结果进行比较,分析三种检查方式的诊断效果,以及对病灶大小和具体病症类型的检查诊断情况。结果超声造影检查诊断的灵敏度、特异度、阳性预测值、阴性预测值以及诊断符合率均明显高于彩色多普勒超声检查和常规超声检查;超声造影检查的病灶尺寸符合率为85.29%,显著高于彩色多普勒超声检查的55.88%和常规超声的41.18%,彩色多普勒超声检查病灶尺寸符合率高于常规超声(P<0.05);超声造影检查的病变类型符合率为85.29%,显著高于彩色多普勒超声检查的50.00%和常规超声的33.82%,彩色多普勒超声检查病变类型符合率高于常规超声(P<0.05)。结论在肝脏占位性病变的临床诊断中,超声造影检查结果更贴近穿刺活检病理结果,超声造影检查结果的敏感度、特异度、诊断符合率,以及对病灶尺寸和病变类型的诊断符合率,均明显高于彩色多普勒超声检查和常规超声检查,其中常规超声检查的诊断效果最差。

Objective To compare and analyze the effect of ultrasound and color Doppler ultrasound and conventional ultrasound in the clinical diagnosis of liver occupying lesions.Methods From January 2016 to June 2018,78 patients with suspected liver occupying lesions in our hospital were selected as the study subjects,and 68 patients with liver occupying lesions were confirmed by pathological examination.The patients in the group were received ultrasound,color Doppler and conventional ultrasound respectively.Three kinds of examination results were compared with those of biopsy pathology,and the diagnostic results of three kinds of examination methods were analyzed,as well as the diagnosis of the size of the lesion and specific types of diseases.Results The sensitivity,specificity,positive predictive value,negative predictive value and diagnostic coincidence rate of contrast-enhanced ultrasound were significantly higher than those of color Doppler ultrasonography and conventional ultrasonography.The coincidence rate of lesion size of contrast-enhanced ultrasound was 85.29%,significantly higher than that of color Doppler ultrasonography(55.88%)and conventional ultrasonography(41.18%).The coincidence rate of size was higher than that of conventional ultrasound(P<0.05);the coincidence rate of lesion types by contrast-enhanced ultrasound was 85.29%,significantly higher than that by color Doppler ultrasound(50.00%)and conventional ultrasound(33.82%).The coincidence rate of lesion types by color Doppler ultrasound was higher than that by conventional ultrasound(P<0.05).Conclusion In the clinical diagnosis of liver space-occupying lesions,the results of contrast-enhanced ultrasonography are closer to the pathological results of puncture biopsy.The sensitivity,specificity,diagnostic coincidence rate of contrast-enhanced ultrasonography,as well as the diagnostic coincidence rate of size and type of lesions,are significantly higher than those of color Doppler ultrasonography and conventional ultrasonography.The diagnostic effect of conventional ultrasonography is the worst.
