Dystocia, difficult birth due to either a big baby, small maternal pelvis, or malposition of the presenting part is an important obstetric problem and a major cause of emergency caesarean section and birth injury. The risk of caesarean section is 30% for first time mothers who have had their labour induced. We have developed an MRI protocol to assess fetal size and maternal pelvic measurements in supine and upright positions to determine whether they can be used as a predictor of a woman's risk of emergency C-section after the induction of labour.
