Hilly or mountainous surface: a new CT feature to predict the behavior of pure ground glass nodules?

Publication date: 2018Source: European Journal of Radiology Open, Volume 5Author(s): Andrea Borghesi, Silvia Michelini, Francesco Bertagna, Alessandra Scrimieri, Stefania Pezzotti, Roberto MaroldiAbstractPersistent pure ground-glass nodules (pGGNs) typically show an indolent course with very slow growth rates. These slow-growing lesions exhibit different growth patterns regardless of their initial computed tomography (CT) features. Therefore, predicting the aggressive behavior of pGGNs on initial CT remains a diagnostic challenge. The literature reports that computerized analysis and various quantitative features have been tested to improve the risk stratification for pGGNs.The present article describes the long-term follow-up of two pGGNs with different behavior and introduces, for the first time, a new computerized method of analysis that could be helpful for predicting the future behavior of pGGNs.Graphical abstract
