Abstract：Objective To analyze the CT histogram features of cystic fluid in different types of pancreatic cystic neoplasm (PCN),
and provide reference for clinical classification and diagnosis of PCN. Methods A total of 64 patients who were diagnosed as PCN
by postoperative biopsy, including 23 patients with intraductal papillary mucinous neoplasm (IPMN), 21 patients with serous cystic
neoplasm (SCN) and 20 patients with solid pseudopapillary neoplasm (SPN), the clinical data and imaging enhanced CT images of
all patients were analyzed. Results The imaging characteristics of IPMN, SCN and SPN enhanced CT were significant different.
There were statistically significant differences in entropy, 25%, 50% and 75% groups (all P<0.05); multivariate binary logistic
regression analysis combined with receiver operating characteristic to predict the diagnosis of different groups, the results showed
that 25% quantile and the 50% quantile were significantly different between IPMN and non-IPMN. IPMN, SCN and non-SCN, SPN
and non-SPN groups had diagnostic value (P<0.05), and 50% quantile had the best diagnostic efficacy for IPMN and non-IPMN
groups, and 25% quantile had the best diagnostic performance for SCN and non-SCN, SPN and non-SPN groups, with AUCs of 0.918
and 0.838, respectively. Conclusion Different types of PCN cyst fluid CT histogram related parameters have significant differences,
and have good diagnostic performance in differentiating different types of PCN, which can provide a basis for clinical improvement
of the accuracy of non-invasive diagnosis of different PCN types.
