| Abstract:: |
| Objective To investigate the relevant data on radiation dose in interventional radiodiagnosis and radiology of adults in Beijing and to provide a basis for establishing relevant diagnostic reference levels (DRLs) in this region. Methods A total of 30 medical institutions in Beijing were surveyed, covering interventional radiodiagnosis and radiology surgeries for coronary artery, structural heart diseases, permanent cardiac pacemaker implantation, electrophysiological study and radiofrequency ablation, nervous systems, abdominal systems, and the blood vessels of the lower limbs. The primary parameters investigated included the air kerma area product (PKA) and incident air kerma (Ka,r). The 75th percentiles of radiation dose were considered DRLs, which were analyzed at both the overall and individual medical institution levels. Results A total of 3 331 cases of the abovementioned radiodiagnosis and radiology surgeries were collected. The DRLs (i.e., PKA and Ka,r) of various diagnostic examinations were 37.87 Gy·cm2 and 509.00 mGy for coronary artery, 9.34 Gy·cm2 and 48.00 mGy for electrophysiological study and radiofrequency ablation, 218.50 Gy·cm2 and 901.70 mGy for nervous systems, 81.00 Gy·cm2 and 302.20 mGy for the abdominal system, and 83.37 Gy·cm2 and 214.69 mGy for the blood vessels of the lower limbs. In contrast, the DRLs (i.e., PKA and Ka,r) for interventional radiodiagnosis and radiology were determined at 135.00 Gy·cm2 and 1 897.58 mGy for coronary artery, 26.91 Gy·cm2 and 172.30 mGy for structural heart diseases, 27.77 Gy·cm2 and 87.75 mGy for permanent cardiac pacemaker implantation, 34.46 Gy·cm2 and 247.00 mGy for electrophysiological study and radiofrequency ablation, 214.36 Gy·cm2 and 1282.80 mGy for the nervous system, 196.64 Gy·cm2 and 875.71 mGy for abdominal system, and 108.25 Gy·cm2 and 523.25 mGy for the blood vessels of the lower limbs. Conclusions The DRLs of radiation dose in interventional radiodiagnosis and radiology in Beijing were determined through a survey and statistic analysis. These findings suggest that for certain interventional procedures, the optimized radiation protection should be enhanced. |
