Conclusion
♦This work studied crucial factors affecting cephalic doses to IRs such as
- the type of the procedure
- the standing position of IR
- the IR’s experience
- the use of radiation protection tools
♦Doses to the left head side were significantly higher than corresponding ones to the right side (p=0.005),
reflecting IR’s position (Figures 2-4)
♦The highest dose per procedure was recorded to the left eye lens in vertebroplasties (1762 μSv) (Figure 4)
♦Data presented in Figure 5 suggest a more effective use of radiation protection equipment by experienced physicians
♦ The strong linear relationship between eye lens dose and ipsilateral forehead dose suggest that measurement of the lens dose can provide a good estimation of the forehead dose and vice verca (Figure 6)
♦The non-use of the appropriate radiation protection tools,
such as lead glasses,
may result in exceeding the new occupational dose limit for the eye lens (Figures 7 & 8)
♦It is imperative that a strict educational program on radiation protection is applied in all interventional radiology departments
