I guess I should clarify further - gamma rays are not technically in the 
light spectrum- they are electromagnetic radiation, therefore are in the 
electromagnetic spectrum, along with radio waves, microwave, infrared, 
visible light, UV, and x-ray.  

sorry- physics OCD kicked in.

Steve 

I actually had this come up not that long ago and discussed it with a cath 
lab/nuclear tech. 

Nuclear heart tests use a radioactive dye and gamma rays to image. None of 
which should be affected by fluorescein. Gamma rays higher in the light 
spectrum than x-rays, whereas fluorescein light absorption and excitation 
is in the 485-500 nm range. Hope this helps

 Hi all. I ran across something today that I haven't encountered in over 15 
years in ophthalmic photography, which is surprising in this case. A 
physician ordered an FA on a patient who was scheduled to have an IVP of 
sorts ( the patient called it a nuclear test on their heart ) at 12:00 the 
same day.  The question is, is there any contraindications to having an 
IVFA 3 hours prior to the "NUCLEAR HEART TEST" We opted out of the FA for 
today as a precaution. Does anyone have a good answer?     Thanks  Steve
