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

Figure 5

The three-dimensional scatter plots of dNIC between malignant and benign nodules in three phases. From the scatter plot, the dNIC distribution of malignant and benign nodules reflects distribution difference of iodine concentration.
