摘要
探讨超声造影与彩色多普勒超声在肝实质性肿块诊断中的应用价值。对难以定性的37例共45个肝实质性肿块均采用超声造影与彩色多普勒超声检查,并将检查结果与手术病理结果对照。结果显示:37例病患的45个肝实质性肿块中,超声造影的检出率为86.67%,较彩色多普勒的检出率44.44%具有明显优势。其中超声造影检测出原发性肿瘤有26例,而彩色多普勒超声仅检测出13例,漏诊较多。而用两种方法对肝实质性肿块进行检测发现,对>30 mm肿块的准确率两种方法都达到了100%的准确度,但对于10~30 mm和<10 mm的肿块,彩色多普勒超声的准确率明显处于弱势,其对10~30 mm的肿块的检出准确率仅为76.19%,而超声造影对<10 mm的肿块的检出准确率都有77.86%,其对10~30 mm的肿块检出准确率更是高达90.48%。37例患者均成功进行超声造影检查,除2个肝孤立性坏死结节外,45个肝实质性肿块中43个病灶均在不同时相出现不同程度的强化现象,造影剂无退出可能为良性病灶,造影剂早期退出病灶可能为恶性病灶;超声造影对肝实质性肿块的检出率显著高于彩色多普勒超声(p<0.05),且对其大小的检测准确率也显著高于彩色多普勒超声。与彩色多普勒超声相比,超声造影技术诊断难以定性的肝实质性肿块的准确率较高,对鉴别诊断肝实质性肿块的良恶性具有重要意义,可为临床诊断治疗提供重要的影像学依据。
The aim of this study was to investigate the value of contrast-enhanced ultrasonography and color doppler ultrasonography in the diagnosis of hepatic parenchymal masses. 37 cases patients about 45 cases of hepatic parenchymal tumors, which were difficult to be identified, were examined by contrast enhanced ultrasonography and color doppler ultrasonography, and the results were compared with the results of operation and pathology. The results showed that the detection rate of CEUS was 86.67% in 45 liver parenchymal masses of37 patients, and the detection rate of color doppler ultrasound was 44.44%, so CEUS had obvious advantages.There were 26 cases of primary tumors detected by CEUS, while only 13 cases were detected by color doppler ultrasound with many missed diagnosis. When the liver tumors were detected by two methods, the accuracy of the two methods on tumors 30 mm all reached 100%, but for 10-30 mm and 10 mm mass, the accuracy rate of color doppler ultrasound was lower. The accuracy rate of the detection of 10-30 mm mass was only 76.19%, the accuracy rate of CEUS in detection of tumor 10 mm was 77.86%, and the 10-30 mm mass detection accuracy rate was as high as 90.48%. 37 cases were successfully performed ultrasound examination, except the 2 solitary necrotic nodule of liver. Of the 45 hepatic parenchymal masses, 43 lesions showed different enhancement at different phases. No withdrawal of the contrast medium might be a benign lesion, and an early withdrawal of the contrast agent might be a malignant lesion. The detection rate of contrast-enhanced ultrasound in hepatic parenchymal masses was significantly higher than color doppler ultrasound（p〈0.05）, and the detection rate of the tumor size was also higher than that of color doppler ultrasound. Compared with color doppler ultrasound,contrast-enhanced ultrasound had higher accuracy ratein diagnosis of liver tumors that were difficult to quantify,which had important significance for differential diagnosis of benign and malignant liver tumors, and could
