Among the 175 patients with resected IPMN in our study, 101 (57.7%) patients have been previously reported. Previous study focused on the postoperative death or recurrence based on the MRI features. In the current study, we compared diagnostic abilities between CT and MRI for predicting malignant IPMNs, focusing on the identification of the high-risk stigmata and worrisome features of pancreas IPMN on each imaging modality.
