5 Conclusion
The findings of this comprehensive study underscore the limitations of traditional methods for estimating radiation dose in CTPA examinations. The observed underestimation of patientspecific exposure using the standard CTDI highlights the need for more personalized dosimetry approaches that account for individual anatomical variations. The use of SSDE based on water-equivalent diameter demonstrated improved accuracy compared to effective diameter-based SSDE, yet notable variability persists, emphasizing the complexities of thoracic tissue composition. The strong correlations between patient lateral diameter and both SSDE metrics reinforce the importance of considering morphological factors in dose calculations. As CTPA utilization rises in the post-COVID-19 era, these insights contribute to ongoing efforts to enhance radiation safety through the refinement of dose estimation methodologies. Implementing personalized, sophisticated techniques will optimize radiation exposure while preserving the diagnostic efficacy of this critical imaging modality, ultimately improving patient care and outcomes.
