Spectral CT Analysis of Solitary Pulmonary Nodules for Differentiating Malignancy from Benignancy: The Value of Iodine Concentration Spatial Distribution Difference

Figure 4

An 80-year-old man with adenocarcinoma in the inferior lobe of right lung. Pseudocolor images of spectral CT on the artery phase can visually display distribution difference of iodine concentration based on blood supply in tumor by different colors. The color in proximal region was brighter than that of distal one.
