Objective: The aim of our study was to analysis the pictures of conventional magnetic resonance imaging (MR), dif usion-weighted imaging (DWI) and dynamic enhanced magnetic resonance imaging (DEMRI) of pancreatic endocrine tumors (PETs), and evaluate diagnostic value of MR, DWI and DEMRI for diagnosing PETs. Methods: DWI and DEMRI scanning toward 13 patients with PETs being confirmed by surgical pathology before surgery on the basis of conventional MR scanning were carried out, and MR findings was analyzed retrospectively. Results: Of 13 patients with PETs there was 11 cases with single lesion, 2 with multiple, and had 15 lesions altogether, of which there were 3 lesions in pancreatic head, 1 in its neck, 2 in its body, 4 in its body and tail, 5 in its tail. MR findings: (1) T1WI signal was low or slightly lower (9/15), and equal ones (5/15); (2) T2WI showed high or slightly higher signal (10/15), and equal ones (5/15); (3) T1WI with fat suppression: the signal was low (11/15), mixed signal (2/15), and equal ones (2/15); (4) DWI: normal pancreatic tissue exhibited homogeneous intermediate signal, al 15 lesions were high or slightly higher signal, the measuredADC values of tissue of PETs was (1.124 ± 0.252) × 10-3 mm2/s, and the ADC value of normal pancreatic tissue (1.873 ± 0.157) × 10-3 mm2/s; (5) Enhanced (M3D/LAVA) scanning: among 13 patients with PETs there were 12 pancreatic lesions with significantly enhanced signals in the arterial phase in al 15, and significantly higher than normal pancreatic tissue, and two slight enhancement was slightly higher signal;and 1 no enhancement. Enhanced pattern: homogeneous enhancement were 6 lesions, and the heterogeneous 4, and the edge ring 5. Conclusion: MR and DWI combining with DEMRI help qualitative diagnosis of pancreatic endocrine tumors.
