Chi-square goodness of fit test

Hi all,

I'm currently conducting research at a radiology department. The setup of our research is that we let 2 radiologists indicate their preference for a scan (either the left of the right scan) with the scan information etc. hidden.

We want to show that the preference for 1 type of scan is significantly different compared to the other type. My question is, what is the best statistical way to show this?

I was thinking about using the Chi-square goodness of fit test, but haven't really come across this test in articles. Perhaps you have additional suggestions?

Thanks for your time.

the simplest way would be to just calculate the percent left scans, say, and do a one sample p test against 50%
