| Outline of Final Research Achievements |
Currently, there is an immediate need for computer-aided diagnosis software that can assist radiologists accessing tumor response to cancer therapy, in particular molecular targeted therapy, because radiologists have to examine a quite large number of images in daily practice by using some complicated diagnostic criteria. We tested a novel machine learning technique named CARTA (Clustering-Aided Rapid Training Agent) for classifying MR images of various animal models, including pancreatic and colorectal cancer models. We acquired MR images of these animal models by using high-field (3.0 or 9.4 tesla) MR scanners. Our results showed that CARTA is a promising technique to classify MR images based on the similarity in image features. We contend that CARTA can produce software that can predict tumor response to various cancer therapies including molecular targeted therapy and radiation therapy based on MR image features.
