Abdominal versus vaginal ultrasound

Colleagues-

A patient of mine presented to the emergency department (ED) one night complaining of light vaginal bleeding at 6 weeks gestational age. She was concerned about a possible miscarriage. The ED doctor ordered a pelvic ultrasound as part of the work-up, but the patient, who has a medical background, refused the foley catheter and abdominal ultrasound. Instead, she asked for a vaginal ultrasound. The radiologist on call demanded that an abdominal scan (with foley catheter in place) be performed first, followed by a vaginal ultrasound to "make sure that nothing is missed."

I have found this unusual, and I think faulty, logic at every hospital I have been to. The radiologists claim that some things can be missed by vaginal ultrasound and that it's the standard of care to perform both an abdominal, and then a vaginal, ultrasound.

Why put the patient through the discomfort of the catheter with a full bladder, and the (probably small) risk of urinary tract infection when doing an abdominal scan when a vaginal ultrasound is much better at providing information with a 6 week pregnancy? The radiologist seemed to think I was out of my mind for suggesting he bypass abdominal scans on all my future patients with similar complaints. Any thoughts from the group?

Thanks,
