Gummie,
No No, my detailed scan involved everything liao. We saw all the organs developing well. That includes spinal cord, brain, legs, hands, heart, blood flow, nose, lips, neck, etc etc. The gender was just a small part of it as we did not get to know the gender in week 15.
I dunno how many detailed scans there are. I only know there will be another one in week 30s.
Oh, the one u had previously was NT scan. That one only to check for thickness of the neck rite? A detailed scan takes a very long time to complete. Mine took around 45 mins.
