Fig. 5From: Differential diagnosis of benign and malignant patchy ground-glass opacity by thin-section computed tomographyA 41-year-old male with benign patchy GGO. a An ill-defined patchy pGGO locates in the subpleural zone of the right lower lobe. Multiple peripheral vessels can be detected in it. Coronal (b) and sagittal (c) images show that the lesion has a wide base. d VR image shows that the lesion is located in the subpleural zone, the adjacent big vessels are not involved. GGO, ground-glass opacity; pGGO, pure ground-glass opacity; VR, volume renderingBack to article page
