Title
Determining the prevalence and misclassification of perifissural nodules in the NLST.
Summary
Intra-pulmonary lymph nodes are defined by certain morphological features on a CT, though without pathological confirmation such an abnormality is commonly termed perifissural nodule (PFN). Previous observer studies have shown that nodules labeled as PFNs have a negligible chance of being malignant. This project aims to determine whether the results of this classification system also applies to NLST scans.
Aims

- To estimate the prevalence of perifissural nodules in the NLST.
- To determine how often cancers are misclassified as PFNs.
- To attempt modifying and testing other versions of the PFN classification system.
