Outline of Final Research Achievements

The purpose of this study was to develop and evaluate the effectiveness of a computerized approach that detects metastatic diseases in lympha node, liver, and lung from colorectal cancer. For that, we performed the following four subprojects; (1) establishing a database of torso CT images with contrast material and diagnosis reports, (2) developing a structure analysis method of vessel network in torso organs, (3) developing a detection method of metastatic diseases in lymapa node, liver, and lung through vessel network analysis, and (4) developing computer-aided detection system of metastatic diseases. Preliminary experimental results using the established database suggested that the quantitative analysis of vessel network structures in torso organs can characterize indications of metastatic diseases which are spread from colorectal cancer.
