3D CT reconstruction shows ties to malignant pulmonary nodule growth

3D reconstruction of CT images could aid in follow-up strategies for pulmonary nodule screening, a study published November 15 in the Journal of Cardiothoracic Surgery found. Researchers led by Wenfei Xue from Hebei Province General Hospital in Shijiazhuang, China, found through such reconstruction that the tumor blood vessel diameter of ground-glass opacity (GGO) lesions are tied to the growth of malignant pulmonary nodules. “The identification of ground-glass nodule (GGN) growth is a complicated task,” Xue and co-authors wrote. “However, the pulmonary nodules growth with GGO can be predicted by considering the clinical responses and morphological features in CT images, such as parents’ age and the diameter of tumor blood vessels.” While blood perfusion has a significant role in assessing tumor progression, this relationship is unclear in patients with persistent pulmonary nodules with GGO. In CT imaging, GGO refers to the increased density inside the lungs. This presents as a foggy or frosty shadow, but not enough shadow to mask the vascular and bronchial texture, the researchers noted. Xue and colleagues investigated the relationship between tumor blood vessel and the growth of persistent malignant pulmonary nodules with GGO. To reveal the morphological features from collected CT images, the team performed multiplane reconstruction and 3D volume-rendered using PACS system (Neusoft Medical Systems) and a commercially available 3D reconstruction system (InferRe...
