摘要

在沙特阿拉伯,放射检查的使用正在迅速增加。据估计,沙特阿拉伯王国7.1%的人口是残疾人。在3294万公民中,有1445723万人(男性占52.2%,女性占47.8%)被认为是残疾人。残疾人经常接受医学成像程序,关于这些机器对残疾人的辐射暴露风险的研究还不够。本研究旨在量化医疗程序的频率,并估计残障个体的集体剂量,以预测医疗暴露的整体癌症风险。共对残疾患者进行了108次计算机断层扫描(CT)。手术包括脑部、胸部、腹部、骨盆和颈椎。本研究使用的128层CT机为Philips Ingenuity (Philips, Netherlands)。CT机定期接受质量控制测试,以确保符合国家建议。本研究在哈立德国王医院和苏丹王子中心的放射科对108例残疾患者进行了CT检查[女性11例(10.2%),男性97例(89.8%)]。脑、胸、腹、骨盆、颈椎每次CT扫描的平均辐射剂量[DLP (mg .cm)]分别为1183.4±187、352.8±88、654±73、803±800、527±186。估计的癌症风险是每1000到10000个CT手术中有1个癌症。患者的剂量与以前对正常患者进行的研究相当。然而,保护残疾患者免受不必要的辐射暴露对于减少预计的辐射风险和减少重复CT扫描和非生产性辐射暴露的次数至关重要。

Assessment of the Radiation Exposure and Cancer Risks of Disabled People Undergoing Different Computed Tomography Scans
The usage of radiological investigations is increasing rapidly in Saudi Arabia. It has been estimated that 7.1% of the populace in the Kingdom of Saudi Arabia is disabled. Out of 32.94 million citizens, 1,445,723 (52.2% males and 47.8% females) millions are considered disabled. Disabled individuals are frequently undergoing medical imaging procedures, and there are not enough studies regarding the risk of radiation exposure to disabled patients from these machines. This study aims to quantify the frequency of medical procedures and estimate the collective dose for disabled individuals to predict the overall cancer risk from medical exposure. A total of 108 computed tomography (CT) procedures were carried out for disabled patients. The procedures include the brain, chest, abdomen, pelvis, and cervical spine. A 128-slice CT machine was used in this study Philips Ingenuity (Philips, Netherlands). The CT machine is subjected to regular quality control tests to ensure compliance with national recommendations. In this study, 108 [11 (10.2%) females and 97 (89.8%) males] CT procedures were carried out for disabled patients at the radiology department, King Khalid Hospital and Prince Sultan Center. The average and standard deviation radiation dose per CT procedure [DLP (mGy.cm)] for the brain, chest, abdomen, pelvis, and cervical spine were 1183.4 ± 187, 352.8 ± 88, 654 ± 73, 803 ± 800, and 527 ± 186, respectively. The estimated cancer risk is 1 cancer per 1000 to 10,000 CT procedures. Patient doses are comparable with those of previous studies carried out for normal patients. However, the protection of disabled patients from unnecessary radiation exposure is crucial to reduce the projected radiation risks and minimize the number of repeated CT scans and unproductive radiation exposure.
