How much X-ray exposure is there in epidural steroid injection?

Great Question. Depends on type of c-arm used and whether or not physician/x-ray tech continuously steps of pedal or presses button or is more cautious. I use a setting called low-dose pulse and often the exposure is less than 1/100 of a chest x-ray.
Very low. While they use a fluoroscope to guide injection the exposure of areas other than the target tissue exposure of other tissues are negligible.
Very Little. You get way more Xray exposure with a chest Xray...
Very Little. The patient only gets a few brief bursts of xray exposure. Overall it is very little.
