超声造影在慢乙肝肝内中小型局灶性病变的诊断价值

Diagnostic value of contrast-enhanced ultrasound in small and medium-sized liver lesions of chronic hepatitis B

目的:探讨慢性乙型病毒性肝炎患者肝内中、小型局灶性病变在超声造影表现典型与否对临床处理的指导意义。方法:对85例慢性乙型病毒性肝炎患者肝内单个占位性病变(≤5.0 cm)进行超声造影,根据病灶是否为典型增强模式而行不同的临床处理。结果:85例病灶中,72例行手术或随访追踪,13例行穿刺活检。运用此法诊断各种病灶的灵敏度、特异性、阳性预测值和阴性预测值平均值分别是90.8%、99.2%、98.0%和95.3%。结论:慢性乙型病毒性肝炎患者肝内中、小局灶性病变的超声造影增强模式典型与否对指导临床处理具有重要价值。

Objective:To explore the significance of contrast-enhanced ultrasound in the diagnosis of chronic hepatitis B.Methods:85 cases of chronic hepatitis B patients with single occupying lesion of the liver(less than 5.0cm)were detected by ultrasound contrast,then they were given different clinical treatment according to the typical enhancement pattern.Results:Among the 85 lesions,72 cases underwent operation or follow-up,and 13 cases underwent biopsy.The sensitivity,specificity,positive predictive value and negative predictive value of this method for diagnosing various lesions were 90.8%,99.2%,98.0%and 95.3%respectively.Conclusion:The model of enhanced ultrasound contrast enhancement in liver and small focal lesions in patients with chronic hepatitis B has great value for guiding clinical treatment.
