Background: Cystic fibrosis (CF), a hereditary disorder affecting the respiratory and digestive systems, poses intricate challenges in diagnosis and management. Objective: The primary aim was how anatomical location and observer experience influence chest tomosynthesis visibility in CF patients in Pakistan. Methodology: This prospective observational study was conducted at MCM/ Muhammad Teaching Hospital in Peshawar. The sample size comprised 6 CF patients, determined through statistical calculations, ensures representation of observer experience levels and anatomical variations. Independent variables include anatomical location and observer experience, while the dependent variable is the visibility of structures in chest tomosynthesis images. Statistical analyses, including ANOVA and regression using SPSS (version 27), are complemented by qualitative analysis of observer feedback. Results: The study reveals a significant impact of anatomical location on visibility (p < 0.05). Novice observers demonstrate lower visibility percentages than Intermediate and Expert observers, emphasizing the pivotal role of observer expertise. Key results include specific visibility percentages for Novice (Upper Chest: 82%, Middle Chest: 90%, Lower Chest: 85%), Intermediate (Upper Chest: 88%, Middle Chest: 92%, Lower Chest: 87%), and Expert (Upper Chest: 97%, Middle Chest: 95%, Lower Chest: 100%) observers. Correlation and regression analyses indicate a moderate positive correlation (r=0.65) between observer experience and overall visibility. Conclusion: The study underscores the necessity of tailored imaging strategies in Pakistan, emphasizing the diminished visibility among novice observers and highlighting the critical role of experienced healthcare professionals, contributing valuable insights for refining cystic fibrosis diagnostic practices and advocating continuous improvement in imaging methodologies for enhanced patient outcomes.
