Corrected entry: Abby diagnosis a 'piece of metal in his spleen' when treating Susan's husband who has just collapsed. She puts the ultrasound machine beside his right hip when the spleen is located behind the last rib on the left. Also metal would not show up on ultrasound.
Corrected entry: None of the babies that are born in this episode have umbilical chords.
Correction: I think you'll find that Dr Weaver's baby has an umbilical chord as Neela asks her if she'd like to cut it.
Correction: Actually, since ultrasound scans are based upon the principle that high frequency soundwaves are reflected, metal shows up very well on an ultrasound. It would appear as bright white since it is dense and would reflect soundwaves very efficiently. Also, they can still use the machine even in that position.
