Table 6.

Using pixel PPI—FFN test set accuracy and AUROC or macro $F1$ (age, BMI, and patient type) for controlled tests. Using full image, CNN test set accuracy and AUROC or macro $F1$ (age, BMI, and patient type) for controlled tests. Single make/model of modality, KVP = 120, exposure mAs = 1 to 4.
