This retrospective study aimed to evaluate the influence of pitch on the Dose Length Product (DLP) in CT Scan examinations used in urography imaging. The study utilized the Statistically Defined Low Contrast Detectability (SDLCD) parameter for analysis. Through this retrospective study, successfully optimizing urography images was achieved by optimizing pitch, resulting in a significant reduction in DLP, almost half of the initial value. The retrospective approach allowed for identifying acceptable parameters within the tolerance limits of good urography imaging while minimizing DLP. The findings of this research provide valuable information for optimizing radiation dosage in CT Scan urography while maintaining image quality. The study offers valuable data for radiology practitioners and experts to determine optimal urography CT scan imaging parameters. Moreover, the results can serve as a foundation for further research to improve radiation dose efficiency in medical imaging. Overall, this study makes a significant contribution to the effort of enhancing image quality and reducing radiation dose risk for patients. Keywords: Urography, CT Scan Optimization, DLP, Pitch, LCD.
