Towards More Structure: Comparing TNM Staging Completeness and Processing Time of Text-Based Reports versus Fully Segmented and Annotated PET/CT Data of Non-Small-Cell Lung Cancer

Table 1

Description of label sets. The specific T-label stage is followed by a morphological descriptor that is stage defining. The N-label is defined by stage (first) and region (second) according to the IASLC lymph node map [35]. The M-label is defined by M stage and metastasis location. Additional findings that are non-NSCLC-related: T_benign referred to a benign lesion, T_other is another primary tumor, N_inflammation is an inflammatory/reactive lymph node, N_other is a nodal metastasis from another primary tumor.
