Abstract Objective: To compare the image quality between iterative model reconstruction(IMR) algorithm and hybrid iterative reconstruction algorithm(iDose3) in the low-dose pelvic trauma CT scan. Methods: A total of 25 pelvic trauma patients underwent pelvis CT scan, with tube voltage 80 kV and automatic tube current. After scanning the date were reconstructed with IMR and hybrid iterative reconstruction iDose3 simultaneously, each named group A and group B. Objective noise and subjective image quality were statistically compared between the two groups with IBM SPSS Statistics 19.0. Results: The image quality of the two groups both met the diagnostic requirement. Both objective and subjective evaluation scores of image quality were higher in group A than group B, the difference was statistically significant(P<0.05). Conclusion: IMR can significantly improve the image quality and reduce the radiation dose in low dose CT scan of pelvic trauma.
