Pancreatic neuroendocrine tumors: Correlation between the contrast-enhanced computed tomography features and the pathological tumor grade

Highlights • Updated WHO classification divided pancreatic neuroendocrine tumors into G1, G2, and G3. • We investigate the relationship between CT findings and pathological tumor grades (G1 and G2). • A larger tumor size was associated with G2 pancreatic neuroendocrine tumors (PanNETs). • Non-hypera...

Zusammenfassung:	Highlights • Updated WHO classification divided pancreatic neuroendocrine tumors into G1, G2, and G3. • We investigate the relationship between CT findings and pathological tumor grades (G1 and G2). • A larger tumor size was associated with G2 pancreatic neuroendocrine tumors (PanNETs). • Non-hyperattenuation during the portal venous phase was associated with G2 PanNETs.
