| Research Abstract |
Using a dual-energy(80 and 140 kVp) mode of a dual-source CT scanner, we confirmed that Iodine concentration in areas with ground-glass attenuation(GGA ;-100 to-700 Hounsfield Unit) could be measured on phantom examination. As a clinical study this method was applied to pre-operative lung cancer patients with or without diffuse lung diseases including a finding of diffuse GGA. The Iodine concentration within the areas of diffuse GGA could also be evaluated and we found a few unknown and interesting CT findings of Iodine concentration of diffuse pulmonary GGA.
