Arggh!!! I almost injured my muscle while doing the NT scan just now. I had 2 patients with thick adiposity which cost me a real struggle to get the right angle for NT. Unfortunately, I couldn't press too hard because of the previous scar. So, I only managed to get 1 good NT fro a really skinny patient (:o) and the other two, I just had to ask them to come again later this week hoping that luck will be on my side to get the Nt and get it done!
