Diagnostic Performance of MRI as an Alternative to CT Following a Non-diagnostic Ultrasonography in Young Women With Acute/Subacute Abdominal Pain : a Prospective Multicenter Study
Diagnostic Performance of MRI as an Alternative to CT Following a Non-diagnostic Ultrasonography in Young Women With Acute/Subacute Abdominal Pain : a Prospective Multicenter Study
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.
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.
