Abstract

Posteroanterior (PA) chest radiography is one of the most commonly performed radiographic procedures to evaluate the lungs and heart. Although considered a low-dose examination, repeated and uncontrolled radiation exposure may still pose risks to patient safety. Therefore, dose estimation is important to ensure that exposure techniques comply with radiation protection principles, particularly the ALARA principle (As Low As Reasonably Achievable).This study aims to estimate the radiation dose using the Dose Area Product (DAP) parameter and analyze the correlation between patient body weight and DAP values. A total of 260 patients undergoing PA chest radiography were included in this retrospective study. Patient characteristics such as body weight, age and sex were recorded along with exposure parameters (kV and mAs) . A normality test was performed, and due to non-normal data distribution, the Spearman correlation test and the Mann Whitney U test were used for statistical analysis. The results showed a statistically significant correlation between body weight and DAP values (ρ = 0.214, p = 0.001), indicating that patients with higher body weight tend to receive slightly higher radiation doses. No significant correlation was found between age and DAP (ρ = –0.083, p = 0.184). Additionally, the comparison of DAP values between male and female patients showed no statiscally significant difference (p = 0.051), although male patients had slightly higher median DAP values.

Abstract

The cross-table lateral projection in femur radiography plays a crucial role in diagnosing lower limb trauma, particularly in critically ill patients who cannot be optimally repositioned. The main challenge in this procedure is maintaining limb stability to achieve optimal image quality while avoiding repeat exposures. Various fixation device innovations have been developed to enhance patient comfort, examination efficiency, and image quality. This study is a systematic literature review conducted using the PRISMA 2020 guidelines, with literature searches performed in PubMed, SpringerLink, and Google Scholar. Keywords included fixation device, cross-table lateral femur radiography, and trauma imaging. Out of 250 identified articles, 35 met the inclusion criteria and were thematically analyzed based on innovation type, design, materials, and clinical effectiveness. Results indicate innovation trends such as portable designs, adjustable modular systems, and the use of lightweight materials like aluminum and velcro straps. Clinically, these devices effectively reduce examination time, improve positional stability, enhance image quality, and minimize operator radiation exposure. In conclusion, innovative fixation devices significantly contribute to optimizing cross-table lateral femur radiography, with recommendations for further prototype development and direct clinical trials.
