Option 1 is incorrect as a marker indicating the time elapsed since the last image is not needed for a PA small intestine projection. Option 3 is also incorrect as the images should be obtained until the barium reaches the terminal ileum, not the right colic flexure. Option 2 is correct as the timing of images starts after the patient ingests the contrast. Option 4 is also correct as the shoulders and ASISs should be positioned at equal distances from the imaging table. Therefore, the best choice is B, which includes options 2 and 4 only.
