3D analysis of solitary pulmonary nodules based on contrast enhanced dynamic CT

In this paper we propose three strategies for analysis of solitary pulmonary nodules in contrast enhanced dynamic CT images. First we collect contrasted images with regale time interval, and we analyze their CT values with respect to the time variation. In the second, we compare the shape spectra characteristic of each contrasted image. The third strategy consists of subtracting the noncontrasted images from contrasted images. The results show that each starkly promise good differentiation between benign and malignant nodule. So we try differential diagnosis
