"One of the most important considerations for a single contrast barium enema is the density of the barium sulfate or water-soluble contrast. If it is too dense, then not only will the fluoroscopic tube "burn out" the background image and obscure overlapping loops, it will also obscure smaller (and sometimes large!) colonic lesions. You want contrast that is dense enough to see filling defects, but not too dense. Where this optimal density lies is dependent on one's fluoroscopic equipment and available contrast solutions. In general, 20% w/v is not a bad target. Water-soluble contrast media (e.g. Gastrografin) should also be diluted to approximately 20%."
"Some radiologists also prefer giving the patient 1 mg of glucagon (IV or SC) before the exam to relax the colon, but this is not mandatory and has questionable utility."

"There are few contraindications. If evaluation of the colonic mucosa is what is clinically desired, then a double contrast barium enema is preferred. If screening for colon cancer, then CT colonography is preferred."
