Fig. 5

Results of LN visual detection and radiomic analysis are represented together on DB1 (left panel) and DB2 (right panel). For each patient, GLSZM ZP and SOLIDITY values are shown. Blue circles correspond to patients with histologically negative lymph nodes, while red circles to patients with histologically positive lymph nodes. Patients with a ‘+’ in the red circle and with a ‘*’ in the blue circle are those which are misclassified by the LN visual detection: in particular, blue circles containing a ‘*’ are false positives at LN visual detection, while red circles containing a ‘+’ are false negatives. The grey area contains patients classified as positive by the univariate radiomic analysis (GLSZM ZP < 0.2755); therefore false positives are blue circles in the grey area, while false negatives are red circles in the white area. The curve line is an example of neural network trained on the 86 DB1 patients
