Fig. 5From: Detector-based spectral CT with a novel dual-layer technology: principles and applicationsImproved lesion conspicuousness. (a) Axial 120-kVp routine diagnostic CT image through the upper abdomen shows a vague ill-defined hypoattenuating lesion in the pancreatic head (arrow). (b) 50-keV VMI at the same level shows excellent contrast opacification of the pancreas, with much improved conspicuity of the hypoattenuating pancreatic head lesion (arrow)Back to article page
