Simple abdomen radiographs show (A) three segments of the colon (right, left, and rectosigmoid colon) and distribution of radiopacity markers (arrows), and (B) before and (C) after 2 weeks of transabdominal functional magnetic stimulation. Three segments were divided with imaginary lines starting from the spinous process of a 5th lumbar vertebra to the upper spinous processes, to passing the right pelvic outlet, and to passing the left iliac crest. To calculate the colon transit time, the number of remaining radiopacity markers were counted and multiplied by 1.2 [15].
