Question

Fluoroscopy cannot be done without a dye.

(a) True

(b) False

I got this question in exam.

The above asked question is from Fluoroscopy in chapter Diagnostic Investigation via Imaging Techniques of Clinical Science

Answer 1

Right answer is (a) True

The best I can explain: Fluoroscopy is a process that depends upon the radioactivity of the dye to show the image. When the dye is injected or ingested, it emits radioactive waves which are captured/recorded using devices. Thus, for fluoroscopy, dye is a necessity.
