MRI with nuclear injection

[COYW]

Hi all. Had another stress test today but this time with an injection containing an isotope that shows up in your heart when you have an MRI afterwards. Since then I’ve been starving and totally knackered 😀 Anyone else had this?

Hi, yeah i had 2 Myocardial Perfusion Scans recently, one with a stress test and the other one was a resting test. I was more hungry after the resting test 😁 and absolutely knackered after the stress test. The stress test included an injection to speed up my heart and cycling on pedals. I had severe chest pain and severe breathlessness for the full 6 mins which probably caused the knackeredness 🤔😂😥

Thanks. I’ve just slept 12 hours. I wonder if the isotope has an effect?
