ABSTRACT:
A method and system of CT colonography is presented that includes the acquisition of energy sensitive or energy-discriminating CT data from a colorectal region of a subject. CT data is acquired and decomposed into basis material density maps and used to differentiate and enhance contrast between tissues in the colorectal region. The invention is particularly applicable with the detection of colon polyps without cathartic preparation or insufflation of the colorectal region. The invention is further directed to the automatic detection of colon polyps.
