| Core Tip |
This study aimed to describe magnetic resonance imaging features of pancreatic neuro-endocrine neoplasms by comparing them to histo-pathology and to determine the accuracy in predicting tumor grade and biological behavior. Beside vascular infiltration and liver metastases, ill-defined margins had high specificity for the identification of G2-3 and stage Ⅲ-Ⅳ tumors (90.3% and 96%, respectively). Lesion size above 17.5 mm had a 91.7% sensitivity in the identification of G2-3 tumors; apparent diffusion coefficient values below 1.21 and 1.28 × 10-3 mm2/s had high sensitivity (70.8% and 80.7%) for the identification of G2-3 and stage Ⅲ-Ⅳ tumors. |
