The growing concern for environmental and patient safety in medical imaging has driven significant advancements in radiological techniques aimed at reducing radiation exposure. This review explores these developments, emphasizing the dual focus on minimizing harm to patients and addressing the broader environmental impact of radiological practices. Recent innovations include the optimization of imaging protocols, the introduction of low-dose imaging technologies, and the integration of advanced software algorithms that enhance image quality while reducing the need for higher radiation doses. The implementation of iterative reconstruction techniques, for instance, has allowed for significant dose reductions in computed tomography (CT) scans without compromising diagnostic accuracy. Additionally, the use of alternative imaging modalities such as magnetic resonance imaging (MRI) and ultrasound, which do not involve ionizing radiation, is increasingly recommended where clinically appropriate, further mitigating radiation risks. Furthermore, the shift towards personalized imaging protocols, where radiation doses are adjusted based on individual patient characteristics, marks a critical advance in patient safety. This approach not only reduces unnecessary exposure but also enhances the overall effectiveness of diagnostic procedures. Environmental safety considerations have also led to the development of more sustainable radiological practices, including the safe disposal of radioactive materials and the reduction of energy consumption in imaging facilities. These efforts are aligned with broader healthcare initiatives to lower the carbon footprint of medical practices. The advancements in radiological techniques to reduce radiation exposure reflect a growing commitment to patient-centered care and environmental stewardship in healthcare. As technology continues to evolve, ongoing research and collaboration between medical professionals, physicists, and environmental scientists will be crucial in furthering these goals. By continuing to innovate and implement safer radiological practices, the medical community can significantly mitigate the risks associated with radiation exposure, ensuring better health outcomes for patients and reducing the environmental impact of radiological services.
