Three-dimensional (3D) images can be generated using thin sections from multi-detector row computed tomography (CT) and computer software, simulating images obtained using conventional ultrasonography (US). This software allows easy diagnosis of abdominal lesions and subsequent treatment of focal liver lesions such as hepatocellular carcinoma (HCC). The present study used newly developed virtual US software for diagnose and treatment of hepatobiliary disease.
The software was used to create virtual US images in 10 subjects. Radiofrequency ablation (RFA) was performed by virtual US in seven patients with HCC.
Slices were easily reconstructed from various angles, and each slice was continuously animated as with conventional US in all subjects. Moreover, when seven patients with HCC were examined using virtual US, HCC nodules were visualized and could be treated with RFA.
Virtual US should prove useful for visualization of HCC nodules that cannot be seen under conventional US. Virtual US is a useful tool for US-guided treatment of HCC.
使用多排探测器计算机断层扫描（CT）的薄层扫描和计算机软件可生成三维（3D）图像，模拟使用传统超声检查（US）获得的图像。该软件便于诊断腹部病变以及后续治疗诸如肝细胞癌（HCC）等肝脏局灶性病变。本研究使用新开发的虚拟超声软件来诊断和治疗肝胆疾病。
该软件用于为10名受试者创建虚拟超声图像。7例HCC患者通过虚拟超声进行了射频消融（RFA）。
在所有受试者中，切片易于从各个角度重建，并且每个切片都能像传统超声一样连续动态显示。此外，当使用虚拟超声检查7例HCC患者时，HCC结节清晰可见，并且可以进行RFA治疗。
虚拟超声对于显示传统超声下无法看到的HCC结节应是有用的。虚拟超声是用于超声引导下HCC治疗的一种有用工具。
