Tridimensional endoscopic ultrasound (3D-EUS) offers a better understanding of the spatial relations of examined lesions and allowing future assessment of the captured volume. 3D-EUS has been used with both radial and linear transducers, especially in an attempt to improve staging of esophageal, gastric, pancreatic or rectal tumors. The AIM of this clinical imaging article was to show the capabilities and perspectives of linear 3D ultrasound, including contrast-enhanced 3D-EUS. The 3D reconstruction images were acquired with a freehand technique through rotation (torque) of the EUS scope along its long axis. 3D acquisition of contrast-enhanced EUS images was also used. Esophageal, gastric and mediastinal tumors are easily visualized by 3D-EUS reconstructions and also, 3D-EUS facilitates anatomical interpretation of the images in the pancreatobiliary area. In conclusion, the advantages of 3D reconstructions in EUS are clear and multiple, especially in the assessment of the location of tumors and their relationships with neighboring organs and blood vessels.
三维内镜超声（3D-EUS）可以更好地了解检查病变的空间关系，并允许对捕获的体积进行未来评估。3D-EUS 已与径向和线性换能器一起使用，特别是在尝试改善食管、胃、胰腺或直肠肿瘤分期方面。本临床成像文章的目的是展示线性 3D 超声的功能和前景，包括对比增强 3D-EUS。3D 重建图像通过超声内镜沿其长轴旋转（扭矩）以自由手法获取。还使用了对比增强 3D-EUS 图像的 3D 采集。食管、胃和纵隔肿瘤可以通过 3D-EUS 重建轻松可视化，并且 3D-EUS 还便于对胰胆管区域的图像进行解剖解释。总之，EUS 中 3D 重建的优势明显且多样，特别是在评估肿瘤的位置及其与邻近器官和血管的关系方面。
