目的比较超声造影与增强CT扫 描在诊断及鉴别肝脏占位性病变的临床 价值。方法 随机选取2012年3月-2015年 3月我院收治的60例肝脏占位性病变患者 作为研究对象，所有患者均接受超声造影 与增强CT扫描，并与手术病理结果对照， 分析超声造影与增强CT的诊断效能。结 果 肝脏良性病变超声造影参数RT、TTP、 mTT均高于恶性病变，PI指数则低于恶性 病变组，良恶性肝脏病变超声造影各参数 对比差异均有统计学意义(P<0.05)；恶性 肝脏病变患者以Ⅰ型曲线形态多见，各类 良性病变则以Ⅱ-Ⅲ型曲线形态多见；超 声造影诊断敏感度与符合率分别为90.5% 与95.0%。结论 超声造影可从形态学、动 态曲线变化及数据测量方面反映肝脏占位 病变影像学信息，诊断符合率高，值得推 广。

Objective To compare the clinical value of ultrasound contrast and enhanced CT scan in differential diagnosis of hepatic lesions. Methods A total of 60 patients of hepatic lesions which admitted into the hospital during March 2012 to March 2015 were selected as the research objects radomly. All patients underwent ultrasound contrast and enhanced CT scan and were compared with pathological findings. The application value of ultrasound contrast and enhanced CT scan in the diagnosis of hepatic lesions was analyzed. Results The ultrasound contrast parameters like RT, TTP and mTT of patients with hepatic benign lesions were higher than those of patients with hepatic malignant lesions while PI index was lower than that in the malignant lesion group. The contrast differences in ultrasound contrast parameters between benign and malignant lesions were statistically significant (P<0.05). Patients with hepatic malignant lesions mainly showedⅠtype curve shapes while various benign lesions mainly showedⅡ-Ⅲ type curve shapes. The diagnostic sensitivity and coincidence rate of ultrasound contrast were 90.5% and 95.0%, respectively. Compared with enhanced CT scan, the difference was statistically significant (P<0.05). Conclusion Ultrasound contrast can reflect the imaging information of hepatic lesions in terms of morphology, changes of dynamic curve, and data measurement. The dianostic coincidence rate is high. It and is worth to be popularized.
