hi, i'm getting ready for a procedure here and don't have time to go into it right now... maybe you can read some of my posts on the QA images (high contrast / low contrast) for CT... it's par for the course to obtain such data during physics acceptance testing done either annually or biannually for both fluoro and CT.

sometimes pulsed fluoro can be somewhat grainy, it's called "quantum mottle," it depends on patient thickness usually, however, we perform all our procedures in pulsed mode with an OEC c-arm... diagnostic images require better contrast...

however, pulsed fluoroscopy can also provide very clear images, again depends on patient thickness... the machine typically adjusts milliamperage to compensate...

long story short, likely not an issue at all...imho and per my dd and experience.

i refer you to please read about pulsed fluoroscopy:

Fluoroscopy: Patient Radiation

Mahadevappa Mahesh, PhD
Fluoroscopic procedures (particularly prolonged interventional procedures) may involve high patient radiation doses. The radiation dose depends on the type of examination, the patient size, the equipment, the technique, and many other factors. The performance of the fluoroscopy system with respect to radiation dose is best characterized by the receptor entrance exposure and skin entrance exposure rates, which should be assessed at regular intervals. Management of patient exposure involves not only measurement of these rates but also clinical monitoring of patient doses. Direct monitoring of patient skin doses during procedures is highly desirable, but current methods still have serious limitations. Skin doses may be reduced by using intermittent exposures, grid removal, last image hold, dose spreading, beam filtration, pulsed fluoroscopy, and other dose reduction techniques. Proper training of fluoroscopic operators, understanding the factors that influence radiation dose, and use of various dose reduction techniques may allow effective management of patient dose.
