Abstract: Objective To explore the imaging findings of branch duct intraductal papillary mucinous neoplasms (BD-IPMNs). Methods A total of 45 BD-IPMNs were confirmed by pathology after surgery.The clinical data and imaging findings were retrospec-tively reviewed.Image analysis included characteristics and the nature of the lesions.Finally,an ROC curve was performed to evaluate the differential diagnostic efficacy between benign and malignant lesions using the imaging findings.Results There were statistically significant differences for differential diagnosis of malignant and benign BD-IPMNs in the maximum diameter of the lesions and the MPD,walls,wall nodules,shape,and the atrophy of pancreatic parenchyma (P < 0.05 ).The diagnostic sensitivity,specificity, AUC and Kappa value of benign and malignant BD-IPMNs were 94.3%,90%,92.1% and 0.81 (P =0.000 1)respectively.Conclu-sion The imaging technology is valuable in diagnosing and differentiating malignant from benign BD-IPMNs.
