    The colon can be examined quickly, efficiently, and without distress by using a single contrast barium technique. For the past year it has been our policy to investigate the colon with a single contrast barium enema technique in frail elderly patients. The use of low viscosity barium suspension, often combined with smooth muscle relaxants, has proved successful in imaging the entire colon. The dilute barium suspension is infused into the rectum under gravity and flows rapidly through …
