Fig. 3From: Application of spectral CT combined with perfusion scan in diagnosis of pancreatic neuroendocrine tumorsFemale, 30 years old, weight 60 kg, the lesion of pNET is located body and tail of pancreatic. A–C are the arterial phase energy spectrum enhancement images 70 keV images, iodine-based images, and water-based images, respectively, with the lesion enhanced to a higher degree than the adjacent parenchyma; D is the arterial phase energy spectrum curve, in which the red line is the lesion curve and the pink line is the normal parenchyma curveBack to article page
