目的探讨超声造影及常规超声在肝局灶性病变(FLL)良恶性鉴别诊断方面的临床价值。方法通过回顾分析筛选出的难于常规超声可靠定性的88例肝脏局灶性病变,在根据常规超声初步判断其良恶性,然后给予超声造影,对造影结果进行分析。结果 88例病灶中病理结果显示33例良性病灶,55例为恶性病灶。超声造影在肝脏肿瘤的良恶性鉴别诊断的敏感性为92.3%,特异性为91.7%,准确性92.0%,明显优于常规超声(P<0.01)。结论超声造影技术极大地提高了肝局灶性病变良恶性的鉴别诊断。
Objective To investigate the clinical value of contrast-enhanced ultrasound and conventional ultrasound in differential diagnosis of benign and malignant focal liver lesions (FLL). Methods 88 cases of hepatic focal lesions, which were difficult to diagnose by conventional ultrasonography, were retrospectively analyzed. The benign and malignant lesions were initially identified according to conventional ultrasound, and then contrast-enhanced ultrasound was performed to analyze the contrast-enhanced results. Results Pathological findings in 88 lesions showed 33 cases of benign lesions and 55 cases of malignant lesions. The sensitivity and specificity of contrast-enhanced ultrasound in the differential diagnosis of benign and malignant tumors were 92.3%, 91.7% and 92.0%, respectively, which were significantly better than those of conventional ultrasound (P <0.01). Conclusion Contrast-enhanced ultrasound can greatly improve the differential diagnosis of benign and malignant focal liver lesions.
