不同模式下C形臂X射线机在腰椎神经根管造影术中产生的辐射剂量比较
Comparison of radiation doses between different modes of C-arm X-ray apparatus applied to lumbar nerve root canal radiography
摘要
Abstract
Objective To compare the effective radiation doses for operators during the single segmental lumbar nerve root canal radiography between pulsed fluoroscopy mode and high contrast fluoroscopy mode of C-arm X-ray apparatus so as to explore the safer fluoroscopy mode of C-arm X-ray apparatus during the operation.Methods Forty-six patients with single segmental lumbar spinal stenosis were randomly divided into Group A(n=24) and Group B(n=22).And the patients of group A and group B received lumbar nerve root canal radiography under high contrast fluoroscopy mode and pulse fluoroscopy mode of C-arm X-ray apparatus respectively.All cases were performed by the same operator.The operative time and fluoroscopy time were recorded,and the effective radiation doses of right opisthenar, left chest and neck were measured for the operator.Results There was no statistical difference in the mean operation time or mean fluoroscopy time between two groups(P>0.05).The mean effective radiation doses of right opisthenar,left chest and neck in Group A were (0.142 ±0.012)mSv,(0.066 ±0.011)mSv and (0.031 ±0.005)mSv,respectively,while in Group B were (0.102 ±0.009)mSv, (0.059 ±0.005) mSv and (0.030 ±0.004) mSv,respectively.The mean effective radiation doses of right opisthenar and left chest in Group B were lower than those in Group A(P<0.05).There was no statistical difference in the mean effective radiation dose of neck between two groups(P>0.05).Conclusion During the lumbar nerve root canal radiography,the pulse fluoroscopy mode is a safer mode and produces lower radiation dose for operator compared to the high contrast fluoroscopy mode.关键词
