1. A non-transitory computer-readable storage device storing computer executable instructions that when executed by a computer control the computer to perform a method for distinguishing invasive adenocarcinoma (IA) from non-invasive adenocarcinoma (AIS), the method comprising: accessing a computed tomography (CT) image of a region of tissue demonstrating cancerous pathology; extracting a set of texture features from the CT image; providing the set of texture features to an automated IA classifier; receiving, from the IA classifier, a classification of the set of texture features; and classifying the region of tissue as IA or AIS, based, at least in part, on the set of texture features and the classification.
