超声造影应用于肝脏局灶病变良恶性定性诊断中的临床价值

Clinical value of contrast-enhanced ultrasonography in the qualitative diagnosis of benign and malignant liver focal lesions

目的探究超声造影应用于肝脏局灶病变良恶性定性诊断中的临床价值。方法选择因肝脏占位病变于我院接受手术或穿刺活检并行病理学检查确诊的117例患者作为研究对象。所有患者采用常规超声及超声造影检查,比较两种诊断方式与病理结果诊断的一致性、诊断符合率、灵敏度、特异度及肝脏良恶性病灶的造影参数。结果超声造影与病理诊断结果的一致性、诊断符合率、灵敏度和特异度均高于常规超声,且超声造影显示肝脏恶性病灶始增时间、达峰时间和增强时间均短于良性病灶(P<0.05)。结论超声造影有利于提高对肝脏局灶病变良恶性的定性诊断能力,应用价值高。

Objective To explore the clinical value of contrast-enhanced ultrasound in the qualitative diagnosis of benign and malignant liver focal lesions. Methods A total of 117 patients with liver space-occupying lesions confirmed by surgery or puncture biopsy and pathological examination in our hospital were selected as the study objects. All patients underwent conventional ultrasound and contrast-enhanced ultrasound. The consistency between the two diagnostic methods and pathological diagnosis, diagnostic coincidence rate, sensitivity, specificity, and the angiographic parameters of benign and malignant liver lesions were compared. Results The consistency and diagnostic coincidence rate, sensitivity and specificity of contrast-enhanced ultrasound and pathological diagnosis were higher than those of the conventional ultrasound (P<0.05). Contrast-enhanced ultrasound showed that the initial time, peak time and enhancement time of malignant liver lesions were shorter than those of the benign liver lesions (P<0.05). Conclusion Contrast-enhanced ultrasonography is beneficial to improve the qualitative diagnosis of benign and malignant lesions in the liver, with high application value.
