To explore the pathogenesis of anterior resection syndrome by magnetic resonance imaging rectal defecography

Figure 2 Utilization of magnetic resonance imaging scanning for the acquisition of dynamic and static rectal images. A: Rectum condition in preparation for defecation; B: Rectum deformation at the beginning of defecation; C: Rectum deformation during defecation; D: Rectum deformation after defecation: E: Rectum deformation at the end of defecation; F: Rectum returns to initial state after defecation (contrast agent downward filling in upper segment).
