In patients with known malignant disease, 51% of liver lesions less than 1.5 cm turn out to be benign. Whether the probability of malignancy is high or low, further investigations are often necessary to definitely exclude malignancy. Contrast-enhanced ultrasonography has a prominent role in lesion characterization with a diagnostic accuracy comparable with computed tomography and magnetic resonance imaging. Anti-angiogenic treatment is common in most oncological institutions and the response evaluation is a new challenge with a research focus on the change in tumour vasculature and perfusion. In planning biopsies, CEUS can identify necrotic and viable areas of tumours and improve the diagnostic accuracy.
在已知患有恶性疾病的患者中，小于 1.5 厘米的肝脏病变有 51%为良性。无论恶性肿瘤的概率高低，通常都需要进一步检查以明确排除恶性肿瘤。超声造影在病灶特征描述方面具有重要作用，其诊断准确性可与计算机断层扫描和磁共振成像相媲美。抗血管生成治疗在大多数肿瘤学机构中很常见，而反应评估是一个新的挑战，研究重点是肿瘤血管和灌注的变化。在计划活检时，CEUS 可以识别肿瘤的坏死和存活区域，提高诊断准确性。
