Conduct Of The Examination (cont.)

11. Roll the patient supine or RPO. Take a spot image of cecum with graded compression.
    
    

12. Turn the patient over to the prone position.

Raise the head of the x-ray table to +45&deg.

Put the enema bag between the patient's legs, and, for a third time, drain barium from the rectosigmoid.

13. Return the table to a horizontal position.  

Add air slowly until the entire colon is well filled. (Let the distension of the transverse colon be your guide.)  

Then, have the technologist take overhead radiographs.
