Impact of exposure parameters on CT image distortion: Clinical study at Al-Sadr educational hospital, Najaf, Iraq

In this research study, the exposure parameters of kilovolt-peak (kVp) and milliampere-second (mAs) were recorded for 20 samples collected from patients who visited Al-Sadr Educational Hospital in Najaf, Iraq, during the period from February to April 2024, which this study aimed to investigate the impact of these exposure parameters on the computed tomography (CT) machine’s image distortion and, consequently, the accuracy of diagnosis. It was found that these exposure parameters are closely related to the accuracy of the resulting image at different rates from one examination to another, so this all leads to the presence of a degree of distortion in the resulting radiographic image, which in turn generates diagnostic errors that affect the treatment plan, which necessitates reviewing the examination protocols of the CT machine to reduce distortion in the radiographic image while maintaining a low absorbed dose, as well as using artificial intelligence (AI) in processing radiographic images to increase image accuracy and thus obtain a better diagnosis.
