Evaluation of the quality of chest x-ray imaging in Benghazi Hospitals

Abstract

Chest radiography (CXR) remains the most fundamental and frequently performed diagnostic imaging procedure in clinical practice. However, its diagnostic efficacy is highly dependent on technical and procedural factors, ranging from patient positioning to exposure optimization. In developing regions, inconsistencies in these variables can lead to poor image quality, potentially compromising diagnostic accuracy and increasing patient radiation dose through unnecessary repeat exposures. Aim of the Study: This study aims to evaluate the overall quality of chest X-ray imaging in Benghazi hospitals. It focuses on assessing technical, procedural, and diagnostic image quality parameters to determine the level of adherence to international clinical and radiological standards. Methodology: A descriptive cross-sectional study was conducted using a structured questionnaire distributed to 120 healthcare professionals. The sample included radiographers, radiologists, consultants, and pulmonologists from both public (67.5%) and private (32.5%) hospitals in Benghazi. Data regarding imaging systems (digital, conventional, and computed), technical practices, and common procedural challenges were analyzed using the Statistical Package for the Social Sciences (SPSS).Results: The findings revealed that the Posteroanterior (PA) projection is the most utilized technique (53.3%). Significant challenges were identified, including difficulties with patient positioning (34.2%) and equipment-related problems (56.7%) that directly affect image quality. The most common technical issues reported were artifacts (37.5%) and underexposure (32.5%). While awareness of radiation dose criteria was generally positive (37.5% reported "Yes"), the use of standardized technique charts varied significantly, showing a statistical association with the age and experience of the radiographer (p = 0.001). Conclusion: The study concludes that while fundamental imaging protocols are generally understood, image quality in Benghazi hospitals is frequently compromised by equipment limitations and procedural artifacts. There is a clear need for regular equipment calibration, the implementation of structured Quality Assurance (QA) programs, and targeted professional training to minimize repeat examinations and enhance diagnostic accuracy.
