Contrast enhanced ultrasound has recently been introduced and is recommended in daily practice in many circumstances, mainly for the detection and characterization of focal liver lesions. Also, contrast enhanced ultrasound has the potential of becoming the primary liver-imaging modality, preceding CT or MR, for the diagnosis of hepatocellular carcinoma in patients with cirrhosis, detection of liver metastases in oncology patients and guidance and assessment of the outcome of percutaneous tumor ablation procedure. Recently, a new imaging technique that combines in real-time, transabdominal ultrasound with CT or MR, has been introduced in clinical practice. Real-time virtual sonography uses a magnetic positioning system attached to the ultrasound probe in order to calculate the spatial position and to display both imaging methods in real-time. Benefits include an increased diagnostic confidence, direct comparison of the lesions using different imaging modalities, more precise monitoring of interventional procedures and reduced radiation exposure. We describe the role of real-time contrast-enhanced and real-time virtual sonography in the assessment of malignant liver lesions.
超声造影技术最近已经问世，在许多情况下，包括肝脏局灶性病变的检测和定性，都已被推荐应用于临床实践。此外，超声造影技术可能成为原发性肝脏成像方式，在 CT 或 MRI 之前，用于诊断肝硬化患者的肝细胞癌、检测肿瘤患者的肝转移，以及引导和评估经皮肿瘤消融术的结果。最近，一种新的成像技术，将实时经腹超声与 CT 或 MRI 相结合，已经引入临床实践。实时虚拟超声使用附在超声探头的磁性定位系统来计算空间位置，并实时显示两种成像方式。其优势包括增加诊断信心、使用不同成像方式直接比较病变、更精确地监测介入性操作和减少辐射暴露。我们描述了实时对比增强和实时虚拟超声在恶性肝脏病变评估中的作用。
