Abstract

BACKGROUND

Iterative reconstruction algorithm (IR) techniques were developed to maintain a lower radiation dose for patients as much as possible while achieving the required image quality and medical benefits. The main purpose of the current research was to assess the level and usage extent of IR techniques in computed tomographic (CT) scan exams. Also, the obligation of practitioners in several hospitals in Saudi Arabia to implement IR in CT exams was assessed.

MATERIAL AND METHODOLOGY

The recent research was based on two studies: data collection and a survey study. Data on the CT scan examinations were retrospectively collected from CT scanners. The survey was conducted using a questionnaire to evaluate radiographers' and radiologists' perceptions about IR and their practices with IR techniques. The statistical analysis results were performed to measure the usage strength level of IR methods.

RESULTS AND DISCUSSIONS

The IR strength level of 50% was selected for nearly 80% of different CT examinations and patients of different ages and weights. About 46% of the participants had not learned about IR methods during their college studies, and 54% had not received formal training in applying IR techniques. Only 32% of the participants had adequate experience with IR. Half of the participants were not involved in the updating process of the CT protocol.

CONCLUSION

The results indicate that the majority of radiographer and radiologist at four different hospitals in Saudi Arabia have no explicit or understandable knowledge of selecting IR strength levels during the CT examination of patients. There is a need for more training in IR applications for both radiologists and radiographers. Training sessions were suggested to support radiographers and radiologists to efficiently utilize IR techniques to optimize image quality. Further studies are required to adjust CT exam protocols effectively to utilize the IR technique.

摘要

背景

迭代重建算法(IR)技术的开发旨在尽可能为患者维持较低的辐射剂量,同时实现所需的图像质量和医疗效益。当前研究的主要目的是评估IR技术在计算机断层扫描(CT)检查中的应用水平和使用程度。此外,还评估了沙特阿拉伯几家医院的从业者在CT检查中应用IR的义务。

材料与方法

近期研究基于两项研究:数据收集和调查研究。从CT扫描仪回顾性收集CT扫描检查的数据。通过问卷调查进行这项调查,以评估放射技师和放射科医生对IR的看法及其对IR技术的应用情况。进行统计分析结果以衡量IR方法的使用强度水平。

结果与讨论

近80%的不同CT检查以及不同年龄和体重的患者选择了50%的IR强度水平。约46%的参与者在大学学习期间未了解过IR方法,54%的人未接受过应用IR技术的正规培训。只有32%的参与者对IR有足够的经验。一半的参与者未参与CT协议的更新过程。

结论

结果表明,沙特阿拉伯四家不同医院的大多数放射技师和放射科医生在对患者进行CT检查时,对选择IR强度水平没有明确或可理解的认识。放射科医生和放射技师都需要接受更多关于IR应用的培训。建议举办培训课程,以支持放射技师和放射科医生有效利用IR技术来优化图像质量。需要进一步研究以有效调整CT检查协议,从而利用IR技术。
