About this trial

This is an interventional diagnostic trial for Acute Abdominal Pain focused on measuring MRI, Acute abdominal pain, Pelvic pain, Diagnostic performance, Young women

Eligibility Criteria

18 Years - 40 Years (Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Women aged 18-40 years old
  • Women referred to CT following a non contributive ultrasonography
  • Women with acute non traumatic abdominopelvic pain (less than 5 day-duration)
  • Women with informed consent
  • Women with affiliation to health insurance

Exclusion Criteria:

  • Women who underwent abdominopelvic surgery in the previous month
  • Suspicion of vital emergency such as shock preventing any delayed management caused by MRI examination
  • Contra-indication to MRI, including pace maker, ferro-magnetic material, foreign bodies with risk of mobilization during MRI examination
  • Women yet included in the study or included in another study
  • Women pregnant (positive beta chorionic gonadotrophic hormone testing) or breastfeeding
  • Women unable to undergo informed consent (vulnerable or protected by law)

5. Study Description

Brief Summary
Objective : To demonstrate diagnostic performances of Magnetic Resonance Imaging (MRI) as compared to Computed Tomography (CT) as a second intention imaging modality in young women with acute non traumatic abdominopelvic pain and non contributive ultrasonography.
Detailed Description
Methods : Consecutive women aged 18-40 years old with acute abdominopelvic pain referred to CT by the emergency Physician or gynaecologist after a non contributive ultrasonography will be included. After obtaining informed consent, all patients will undergo standard CT followed by an additional MRI examination, performed using a short MRI protocol and within 6 hour from CT. The gold standard or reference diagnosis will be established in consensus by an expert panel at 3 months follow up using a standardized diagnosis form. A retrospective reading will be performed independently for CT and MRI by radiologists blinded to the reference diagnosis, using the same standardized diagnosis form. CT and MRI accuracies will be compared.
