Abstract
Purpose
To evaluate, experimentally and clinically, the radioprotective effects of a semicircular X-ray shielding device for operators during CT fluoroscopy-guided IR procedures.
Materials and Methods
During experimentation, the reduction rates of scattered radiation rates from CT fluoroscopy were evaluated using a humanoid phantom. Two shielding device positions were tested: “shielding close to the CT gantry” and “shielding close to the operator”. The scattered radiation rate without shielding was also evaluated. The clinical study retrospectively evaluated the operator’s radiation exposure during 314 CT-guided IR procedures. With a semicircular X-ray shielding device (with shielding group, n = 119) or without it (no shielding group, n = 195), CT fluoroscopy-guided IR procedures were performed. Radiation dose measurements were taken using a pocket dosimeter placed near the operator’s eye. For shielding and no shielding groups, the procedure time, dose length product (DLP), and the operator’s radiation exposures were compared.
Results
Experimentation revealed the respective mean reduction rates of “shielding close to the CT gantry” and “shielding close to the operator” as 84.3% and 93.5% compared with the no-shielding setting. Although no significant differences were found in the procedure time and the DLP between “no shielding” and “with shielding” groups in the clinical study, the operators’ radiation exposure in the “with shielding” group (0.03 ± 0.04 mSv) was significantly lower than in the “no shielding” group (0.14 ± 0.15 mSv; p < .001).
Conclusion
The semicircular X-ray shielding device provides valuable radioprotective effects for operators during CT fluoroscopy-guided IR.
