| Outline of Final Research Achievements |
The purpose of the present study was to investigate the feasibility of determining the invasion depth of colorectal cancers by the quantitative evaluation of basal indentations on CT air-contrast enema images in CT colonography. CT colonography was performed for patients with colorectal cancers using 320-slice MDCT. We demonstrated that quantitative evaluation of basal indentation in CT colonography can improve the diagnostic accuracy of the invasion depth for early CRC.
