Radiation exposure for operators during fluoroscopically controlled vertebroplasty is higher than anticipated, particularly to the hands. This study measured doses, revealing significant hand exposure despite lead apron use, suggesting potential risks of deterministic radiation effects.

Area of Science:

  • Interventional Radiology
  • Medical Physics
  • Occupational Health

Background:

  • Fluoroscopically controlled vertebroplasty is a common procedure.
  • Operator radiation exposure is a concern during interventional procedures.
  • Assessing radiation dose is crucial for preventing deterministic effects.

Purpose of the Study:

  • To measure radiation dose absorbed by operators during vertebroplasty.
  • To evaluate the risk of deterministic radiation effects to the operator.
  • To compare hand dose with lead apron measurements.

Main Methods:

  • 11 consecutive vertebroplasty procedures were monitored.
  • Thermoluminescent ring dosimeters were used for hand dose measurement.
  • Electronic dosimeters measured dose inside and outside lead aprons.

Related Experiment Videos

Main Results:

  • Doses outside lead aprons ranged from 0.022-3.256 mGy.
  • Doses inside lead aprons ranged from 0.01-0.47 mGy.
  • Operator hand doses were significantly higher, ranging from 0.5-8.5 mGy.

Conclusions:

  • Operator hand exposure during vertebroplasty can exceed expectations.
  • Traditional lead apron measurements may underestimate total operator dose.
  • Further investigation into hand shielding and dose reduction strategies is warranted.
