| [ Summary ] |
The advent of multi-slice computed tomography (MSCT) has brought greater speed of acquisition and higher resolution images, with resultant enhancement of image quality and reduced motion artifacts. We have applied MSCT to the visualization of gastric cancer. Various imaging modes of MSCT gastrography, including MPR views for detecting metastatic lesions, will be enhanced with further development of MSCT. However, there are severe limitations to the diagnosis of advanced scirrhous cancer, because metastasis of peritoneal dissemination often happens in these cases. Laparoscopic cytology is still essential for determining proper therapeutic methods. It is important to improve diagnostic performance for determining peritoneal dissemination by utilizing high resolution CT image data from MSCT scanning. MSCT gastrography can become an effective diagnostic tool in scirrhous cancer cases to determine not only clinical staging, but also adaption of laparoscopic cytology. |
