The purpose of this study was to evaluate the usefulness of ultrasound-computed tomography (US-CT) 3D dual imaging for the detection of small extranodular growths of hepatocellular carcinoma (HCC). The clinical and pathological profiles of 10 patients with single nodular type HCC with extranodular growth (extranodular growth) who underwent a hepatectomy were evaluated using two-dimensional (2D) ultrasonography (US), three-dimensional (3D) US, 3D computed tomography (CT) and 3D US-CT dual images. Raw 3D data was converted to DICOM (Digital Imaging and Communication in Medicine) data using Echo to CT (Toshiba Medical Systems Corp., Tokyo, Japan), and the 3D DICOM data was directly transferred to the image analysis system (ZioM900, ZIOSOFT Inc., Tokyo, Japan). By inputting the angle number (x, y, z) of the 3D CT volume data into the ZioM900, multiplanar reconstruction (MPR) images of the 3D CT data were displayed in a manner such that they resembled the conventional US images. Eleven extranodular growths were detected pathologically in 10 cases. 2D US was capable of depicting only 2 of the 11 extranodular growths. 3D CT was capable of depicting 4 of the 11 extranodular growths. On the other hand, 3D US was capable of depicting 10 of the 11 extranodular growths, and 3D US-CT dual images, which enable the dual analysis of the CT and US planes, revealed all 11 extranodular growths. In conclusion, US-CT 3D dual imaging may be useful for the detection of small extranodular growths.
本研究旨在评估超声计算机断层扫描（US-CT）3D 双重成像在检测肝细胞癌（HCC）小的结节外生长中的作用。对 10 例接受肝切除术的单结节型 HCC 伴结节外生长（结节外生长）患者的二维（2D）超声（US）、三维（3D）US、三维 CT 和 3D US-CT 双重图像的临床和病理特征进行了评估。使用 Echo to CT（东芝医疗系统株式会社，东京，日本）将原始 3D 数据转换为 DICOM（医学数字成像和通信）数据，并将 3D DICOM 数据直接传输到图像分析系统（ZioM900，ZIOSOFT 株式会社，东京，日本）。通过将 3D CT 体数据的角度数（x、y、z）输入 ZioM900，以类似于常规 US 图像的方式显示 3D CT 数据的多平面重建（MPR）图像。在 10 例中，病理上共检测到 11 个结节外生长。2D US 仅能描绘出 11 个结节外生长中的 2 个。3D CT 能够描绘出 11 个结节外生长中的 4 个。另一方面，3D US 能够描绘出 11 个结节外生长中的 10 个，而 3D US-CT 双重成像，能够同时分析 CT 和 US 平面，可显示所有 11 个结节外生长。总之，US-CT 3D 双重成像可能有助于检测小的结节外生长。
