目的:探讨超声造影在肝脏低回声病变中的诊断价值。方法:选择在本院诊治的肝脏低回声病变患者68例为研究对象,所有患者均实施超声造影检查,并与临床病理诊断结果对比,分析超声造影诊断的准确率和误诊率。结果:超声造影检查结果显示良性病灶48例,恶性病灶18例,2例病变性质不明确。临床病理分析确诊良性病灶48例,恶性病灶17例,2例不明确性质为炎性病灶,1例病理不明确。超声造影检查良性病变48例和17例恶性病变与病理诊断相符,超声造影诊断准确率为95.58%,1例患者实为血管瘤造影误诊为肝癌,误诊率为2.94%。结论:超声造影技术是一项辨别性高、安全性强、无创伤性的检查诊断技术,能有效提高临床诊断准确率,避免误诊漏诊的现象发生,为临床尽早治疗提供可靠诊断依据,值得在临床推广应用。
Objective: To investigate the diagnostic value of contrast-enhanced ultrasound in hypoechoic lesions of the liver. Methods: Sixty-eight patients with hypoechoic lesions were selected for study. All patients underwent contrast-enhanced ultrasonography. Comparing with the clinicopathological results, the diagnostic accuracy and misdiagnosis rate of contrast-enhanced ultrasound were analyzed. Results: Contrast-enhanced ultrasound showed 48 cases of benign lesions, 18 cases of malignant lesions and 2 lesions of unknown characteristics. Clinicopathological analysis confirmed 48 cases of benign lesions, 17 cases of malignant lesions, 2 cases of indefinite nature of inflammatory lesions, 1 cases of pathology is not clear. 48 cases of benign lesions by ultrasound contrast and 17 cases of malignant lesions were consistent with the pathological diagnosis. The accuracy of contrast-enhanced ultrasonography was 95.58%. One case was misdiagnosed as hepatoma with angiography, the misdiagnosis rate was 2.94%. Conclusion: Contrast-enhanced ultrasound is a highly accurate, safe and noninvasive diagnostic technique that can effectively improve the accuracy of clinical diagnosis and avoid misdiagnosis and missed diagnosis. It provides a reliable basis for early clinical treatment and is worthy of Clinical application.
