Abstract
In interventional radiological procedures, the individuals conducting the procedure and the patient are exposed to radiation, which is one of the disadvantages of interventional radiological interventions. However, it is crucial to know the exact amount of radiation exposure for both the patient and the physician, depending on their positions, to prevent early or long-term complications. In interventional radiology, medical personnel must protect themselves from radiation. Today, dosimeters are used to monitor the radiation exposure of medical personnel, with special personal radiation protection registration numbers used to control the dose. Furthermore, protective clothing has been shown to effectively shield against radiation, significantly reducing the amount of radiation absorbed by medical personnel. In the present study, the radiation dose was measured using five RaySafe Live dosimeters during port placement through fluoroscopic imaging in 30 patients (14 females, 16
males). Three dosimeters were placed in the upper collar area (right, center, left), one under the apron of the interventional radiologist, and one on the C-arm. Statistical
analyses and graphics were performed using JASP, Python, and Microsoft Office programs. The study results showed that the radiation dose varied significantly depending on the side on which the port placement was performed. For port placements on the left side of the patient, the radiation dose was approximately twice as high as for implantations on the right side. Four dosimeters were provided to the interventional radiologist, and it was determined that the measurements from these dosimeters significantly differed from each other in a statistical sense (p<.05). There was also a statistically significant correlation between the patients' body mass index, the cut-off time, the patients' radiation dose, and the three dosimeters placed on the collar area of the radiologist (p<.05). The protective equipment can be used for the entire body. However, the mobile lead glass shield, which provides very good radiation protection for the head and neck, can hardly or not at all be used for procedures like port placement, thus limiting protection in these cases. Nevertheless, the maximum annual effective radiation dose according to the International Commission of Radiological Protection standards cannot be reached through port placement alone.
