This study was carried out to ascertain the clinical usefulness and problems of three-dimensional (3D) images obtained with the ultrasound probe.
Eighteen resected specimens and 21 patients were examined. After the images were recorded on video, 3D displays were produced using a workstation.
In the in vitro study the surface images were quite consistent with the macroscopic findings in 17 cases. In 2 esophageal cancers, 7 of 10 gastric cancers, and 2 colonic cancers the depth of tumor invasion was assessed accurately from the reconstructed images. In the in vivo study although 3 D display had some limitations, it was useful in esophageal and rectal lesions.
This new diagnostic method could visualize the 3D extent of gastrointestinal lesions and appears to have a useful clinical application.
本研究旨在确定超声探头获取的三维（3D）图像的临床实用性及问题。
对18个切除标本和21例患者进行检查。在将图像记录到视频后，使用工作站生成三维显示。
在体外研究中，17例表面图像与宏观发现相当一致。在2例食管癌、10例胃癌中的7例以及2例结肠癌中，可从重建图像准确评估肿瘤浸润深度。在体内研究中，尽管三维显示有一些局限性，但对食管和直肠病变有用。
这种新的诊断方法可以可视化胃肠道病变的三维范围，似乎具有有用的临床应用价值。
