[Invited Talk] Computer-aided Detection of CT Colonography

Abstract (in Japanese) (See Japanese page) 
(in English) Computer-aided detection (CAD) for CT colonography is an automated process that detects configurations of the colon wall that might represent polyps. It is a method that has the potential to increase the diagnostic performance of radiologists in detecting polyps and cancers at CTC and to decrease the inter- or intra-observer variability of diagnostic accuracy among readers without significantly increasing the reading time. Preliminary studies have demonstrated that CAD programs are capable of identifying some polyps missed by CTC readers, but at the expense of false-positive findings. Such studies indicate that CAD has the potential to reduce perceptual errors with a relatively low false-positive rate, but further improvements in technology are required. Some of the current challenges faced by CAD researchers are optimizing the trade-off between sensitivity and specificity, establishing a strategy for reading paradigm, developing programs that detect polyps in patients who have undergone stool and fluid tagging, developing other algorithms that are tuned to detect flat polyps or cancers, and insuring that the programs are robust even when ultra-low radiation dose CTC techniques are used.
