text_1: Patient in the hospital with premature rupture of membranes and twins.  I read the RADIUS (Routine Antenatal Diagnostic Imaging With Ultrasound) trial in the New England Journal of Medicine.  I never used to do routine ultrasound but here everybody does it.  I felt vindicated when RADIUS (Routine Antenatal Diagnostic Imaging With Ultrasound) was published.  But I recently went to an OB talk and they were bad mouthing the study.  This patient wanted to know the sex so I ordered the ultrasound and she turned out to have twins.  So now I'm uncertain about whether I should be doing routine prenatal ultrasound.
