Lesion-vessel spatial relationship: a significant indicator for differentiation and evaluation of pulmonary ground-glass nodules.

ABSTRACT:

Background

The role of the lesion-vessel relationship in neoplastic and non-neoplastic ground-glass nodules (GGNs) remains unclear. Thus, this study aimed to investigate the spatial relationship between lesions and vessels of different diameters for differentiating and evaluating GGNs.

Methods

Between January 2019 and September 2023, a total of 1,038 patients with 531 neoplastic GGNs and 531 non-neoplastic GGNs were retrospectively examined. The lesion-vessel spatial relationship was classified into three types: adherence (type I), where a nearby vessel is in contact with the margin of a GGN; surrounding (type II), where the GGN encircles the vessel; and combined (type III). The clinical data, computed tomography (CT) features, and lesion-vessel relationships concerning vary
