Quizplus · Accepted Answer

In a hypersthenic patient, the stomach is more transverse, and the RAO position will foreshorten the stomach and close the lesser curvature. The pylorus is typically centered in the exposure field, and the left lumbar zygapophyseal joints are positioned in the posterior third of the vertebral bodies.
