i am so stoked that you and Jan get on! i love her to bits!

I guess though what she asked is: why would the parents want the scan at 20 weeks. this is sometimes different to why a 20 week scan is performed? maybe it's a way of disseminating what a parent wishes for and what is the role medically of a 20 week scan. (for example, finding gender could possibly be done in lieu of a morphology scan if parents wish it...ie. if they dont want baby exposed to the long morph US if they are only interested in gender...). dunno, i am probably paddling up the wrong river on that one
