Pancreatic Neuroendocrine Neoplasms: Magnetic Resonance Imaging Features and Correlation with Their Histological Grade

#1330

Introduction: Pancreatic neuroendocrine neoplasms (PanNENs) have different biological behavior and prognosis according to their histological grade. At present, few data are available regarding the value of imaging techniques in predicting the grade of PanNENs.

Aim(s): To describe magnetic resonance (MR) imaging features including diffusion-weighted imaging (DWI) of PanNENs according to their histological grade.

Materials and methods: Preoperative MR examinations of 50 PanNEN patients were retrospectively reviewed. Qualitative and quantitative MR features were evaluated by two radiologists by consensus. All MR features were compared between histological grades using chi-square/Fisher’s exact test and Student’s T/ANOVA test. P values <0.05 were considered statistically significant.
