title: Computed tomographic air enema technique to demonstrate colonic neoplasms.
abstract: The use of intravenous glucagon and the judicious introduction of air into a clean colon offer additional help in the confirmation of the larger intracolonic tumors on computed tomographic examination. The procedure is simple and may aid in the differentiation of an intrinsic colonic tumor from other pathologic conditions, particularly those that are extracolonic in origin.
