Dynamic magnetic resonance imaging and transperineal sonography in the assessment of patients presenting primarily with evacuatory difficulty: a short position paper.
Patients presenting with primary evacuatory difficulty have a multiplicity of pelvic floor and perineal soft tissue anomalies. The radiological assessment of these patients requires modalities which monitor the dynamic interaction of pelvic organs during provocative manoeuvres such as straining and simulated defaecation. The advantages and disadvantages of these complementary modalities, (dynamic magnetic resonance imaging, dynamic transperineal sonography and dynamic 2- and 3-dimensional endoanal sonography) are provided in this position paper.
