Abstract：Objective To investigate the effects of micro-CT target reconstruction and IMR reconstruction on pancreatic image
quality. Methods Fifty consecutive patients who underwent pancreatic enhanced CT were divided into three groups according
to the reconstruction method. Group A was the conventional reconstruction method FBP and FOV300; group B was FBP and
FOV150; group C was IMR and FOV150. The scan parameters and reconstruction parameters were the same. The two groups
of image quality were scored by two experienced physicians and the measurements were recorded. The non-parametric test and
analysis of variance were used to compare the image quality of the three groups of patients. Results The three groups (group
A, group B, group C) of abdominal aortic intensive CT were 266.6±25.2, 267.5±26.4 and 267.1±25.8, respectively. There was
no statistical difference between the three groups. The three groups (A group, B group, C group) of image noise were 12.2±2.8,
13.1±3.3, 6.1±1.9, and the noise in group B was larger than that in group A, but there was no statistical difference between the two
groups. Group C The noise was lower than that of group A, and the two groups were statistically different. The SNR and CNR of
group C were significantly greater than those of group A. P was less than 0.05. The scores of group C in the image quality score of the
two doctors were 2.8, which was statistically significant compared with group A and group B. Conclusion Target reconstruction
and IMR reconstruction can significantly improve pancreatic CT image quality and lesion detection rate.
