Dat scan on Thursday- will I get results right away?

I’m a 45 year old female who was diagnosed about 3 months ago based on my clinical exam. They put me on ropinirole and I’ve had great results, which I’m so thankful for. The MDS wanted me to have a DaT scan. The imaging department has given me zero info. They said I get an infusion at 9am and then the scan at 1pm. They didn’t mention drinking anything to protect my thyroid which I read about it online. I was wondering if I will get the results the same day. Just curious about others experience. Thanks in advance!
