Cardiology: is the so-called warm flush feeling one gets from a coronary cta exam the same feeling as the fast hr of a nuclear stress test, or not?

Same & different: The warm flush of a nuclear stress if from regadenoson or adenosine. A coronary CTA uses iodinated x-ray contrast agent - completely different. However, the feeling may feel similar. A flush is a flush. Niacin can do this too. So can being embarrassed.

Not likely: The warm flushing you are getting from a CTA is likely secondary to the IV dye.
