1. Dual energy CT can help to enhance subtle tissue characteristics in the bowel in both benign and malignant disease processes (infectious, inflammatory, GI bleed, small bowel obstruction and neoplasms) with use of iodine map and iodine overlay images. 2. Use of dual energy CT protocols and post processing can be integrated in daily clinical routine to add further insights in bowel imaging.

1. Brief primer of dual energy physics with attention to three-material decomposition and calculation of iodine content for display of iodine maps and virtual noncontrast images. 2. Case-based review of benign and malignant disorders of the bowel in both conventional gray-scale CT images and iodine maps. Emphasis on improved ability to detect and characterize bowel disease through use of dual-energy iodine content information, including the range of infectious, inflammatory, ischemic, and neoplastic bowel pathology. 3. Potential use of dual energy CT and iodine maps in monitoring response to treatment and modulating therapy in patients with benign and malignant bowel diseases.
