Table 4 SC rating normalization
From: Semantic characteristic grading of pulmonary nodules based on deep neural networks
SCs | Low level | High level |
|---|---|---|
Subtlety | Scale 1—2 Poor contrast between nodule and surroundings | Scale 3—5 High contrast between nodule and surroundings |
Calcification | Scale 1—5 Present of calcification | Scale 6 Absent of calcification |
Sphericity | Scale 1—2 Lesser roundness | Scale 3—5 Higher degree of roundness |
Margin | Scale 1—2 Poorly defined margin | Scale 3—5 Sharper margin |
Lobulation | Scale 1—2 None | Scale 3 – 5 Marked |
Spiculation | Scale 1—2 None | Scale 3 – 5 Marked |
