摘要: In this study, the anatomy of anorectum in relation to surrounding structures and anorectal angle were analyzed with magnetic resonance (MR) imaging at rest, during perineal contraction, straining 10 asymptomatic subjects. The intra- inter-observer interpatient variations measurements angle, position junction, plica Kohlrausch rectum established straining. values for junction obtained MR compared standard radiography defecography findings. It was shown that has potential measuring these parameters a more precise patient-friendly way than defecography. Unlike dynamic defecography, is able depict mobility posterior rectal wall. A descent over 20 mm from rest should be considered pathologic. Thi...
