Aim: The aim of this study is the reduction of effective dose for CT scan of brain on traumatic patients in NIMS Hospital, Jaipur, Rajasthan.
Methods: It was an observational descriptive study. A total of 384 patients from the department of Radio-diagnosis and Imaging, NIMS Hospital, Jaipur, were selected and scan was taken at different technical factors.
Result: Out of 384 patients selected for the study, 275 (71.61%) were males and 109 (28.38%) were females. The outcome shows that out of all three groups, males are the most affected traumatic patients when compared to females. Out of the result obtained based on image quality, Group A (with 120 kVp and 450 mAs) and Group B (with 120 kVp and 400 mAs) serves 100% excellent quality images whereas Group C (with 100 kVp and 350 mAs) serves 98.44% average quality images.
Conclusion: Although better image quality needs to be maintained on contradict to this, radiation dose to the patients cannot be compromised for better image quality. Thereby according to cardinal principles for radiation protection, ALARA principles1 need to be implemented at all times. Optimization of technical factors yielded a difference is image quality and Group-B gave the best image quality.
