Abstract: (17 Views) |
Background: The number of fluoroscopy-guided pain procedures using C-arm devices has risen in parallel with the increasing prevalence of spine-related disorders. Although these procedures reduce complications and discomfort for patients, they also increase radiation exposure for patients and medical staff. Materials and Methods: The primary radiation dose received by patients and the secondary radiation dose received by medical staff when a C-arm device used were measured using a variety of dosimeters (XR multidetector, ion chamber gamma survey meter, thermoluminescent dosimeter (TLD). Doses absorbed by patient organs were calculated using MCNP based ALARA-F (mathematical stylized geometry phantom based software). Utilizing the data obtained, permissible daily numbers of procedures were estimated based on radiation dose limits for medical staff and general public. Results: The primary radiation dose directly absorbed by the patient during the C-arm procedure was, on average, 1.5 times higher than the secondary dose measured 30 cm away from the patient. From these observations, the permissible number of procedures per day was calculated to be one for medical staff and zero for the general public without protective gear. However, wearing lead goggles or a lead apron would allow medical staff to conduct up to 28 and 1,000 procedures, respectively, while general public wearing this equipment could attend 6 and 200 procedures, respectively. Conclusion: This study determines radiation exposure levels during C-arm-guided pain relief procedures and advocates for the adoption of protective measures such as lead goggles and an apron to protect medical staff. |
