Objectives:
The goals of this study is to evaluate and compare the irradiation received by the practitioner when performing percutaneous vertebroplasty or kyphoplasty guided by CT and fluoroscopy, for precise anatomical sites.
Methods:
For each intervention, radiothermoluminescent dosimeters were carefully positioned on both orbitals, both hands, and both ankles of the practitioner.
Results:
Twenty-four vertebroplasties were performed in 18 patients and nine kyphoplasties on seven patients. The anatomical site that is most exposed to radiation is the right hand. The two other sites subjected to irradiation are the left hand and the left orbital. This study demonstrates a significant correlation between the irradiation dose and fluoroscopy duration, reflecting both the quantity of primary-beam radiation and backscattered radiation.
Conclusion:
The radiation dose to radiologist is more important for kyphoplasty procedures than vertebroplasty.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
