Acute abdominopelvic pain is a common concern during pregnancy. The differential diagnosis for pelvic pain is extensive and includes multiple non-obstetric etiologies. MRI is effective in evaluating pregnant patients with acute abdominopelvic pain.
MRI provides a complete cross-sectional evaluation of the abdomen and pelvis without radiation exposure or the need for intravenous contrast. MRI can help with the diagnosis in pregnant women with acute pelvic pain expediting treatment, especially when ultrasound results are indeterminate. MRI can also prevent unnecessary surgical exploration which carries a high risk to the pregnancy secondary to preterm uterine contractions.
We provide a list and MR imaging examples of differential diagnoses of acute non-obstetric pelvic pain in pregnancy.
