In this monograph the author has attempted to show the value of the roentgenologic "relief picture" of the colonic mucosa.
The technic for the preparation of the patient for study of the colon is described. The bowel should be entirely empty. This is accomplished by giving enemas several times during the two days preceding the examination. As contrast material the author uses a mixture of three parts of barium sulphate prepared for x-ray work and seven parts of water. The contrast enema is given under fluoroscopic control with the patient in the prone position. The detail studies are made after the bowel has been emptied as completely as possible, the mucosa being covered with only a thin film of the contrast material.
After a short discussion of the anatomy and physiology of the normal colon, the roentgenographic appearance is described and illustrated. Three types are distinguished, namely, the quietly segmenting,
