Fluoroscopy New Update EXAM Questions with
100% Correct Answers
-What does Dynamic means:
-Always active or changing.
-Having or showing a lot of energy.
-Of or relating to energy, motion, or physical force.
Fluoroscopy allows for?
-Imaging of the movement of internal structures. Can visualize function and motion in real time.
-Commonly used for GI, vascular, and urinary studies, ect.
-This often requires the use of contrast media.
When and by whom was fluoroscopy invented?
-Thomas Edison.
-1896
What is the typical X-ray tube current in fluoroscopy?
-5 mA
-Can range from .5 to 5 mA
-Compare this to a radiograph which can range from 50-1200 mA.
