Quizplus · Accepted Answer

The left posterior oblique (LPO) position will best demonstrate the right colic flexure by separating it from the superimposed small intestine. In this position, the patient is lying on their right side with the left leg slightly flexed and the right leg straight. The beam is directed through the right iliac crest and exits the left side of the patient. This position allows for the separation of the ascending colon from the small intestine, making it easier to visualize any defects or abnormalities.
