Contrast-enhanced MDCT in patients with pancreatic neuroendocrine tumours: correlation with histological findings and diagnostic performance in differentiation between tumour grades

•Contrast-enhanced MDCT-features correlate with tumour histology. •Size ≥ 20mm, arterial enhancement ratio <1.1 and late CE are predictive of G2 pNET. •The algorithm allowing the preoperative prediction of G2 pNET is proposed. Aim To identify the multidetector computed tomography (MDCT) features of pancreatic neuroendocrine tumours (pNETs), which correlate with tumour histology and enable preoperative grading. Materials and methods Thirty-nine...
