From: Spectral CT-based radiomics signature for distinguishing malignant pulmonary nodules from benign
Developed integrated model nomogram. The integrated model nomogram was built in training dataset with Zeff-AP and a Rad-score of the selected radiomics features incorporated. Zeff-AP, effective atomic number in arterial phase; Rad-score, the score of spectral CT-based radiomics model combining radiomics scores based on 65 keV images of arterial phase and venous phase
