Author | Training set | Internal test set | External test set | Performances |
|---|---|---|---|---|
Wang et al.25 | 5007 nodules | 351 nodules, including 151 nodules < 1 cm | N/A | CNN showed significantly higher specificity and AUC than radiologists with comparable sensitivity |
In the subgroup of nodules < 1 cm, CNN also showed significantly higher specificity than radiologists | ||||
Li et al.19 | 42,952 patients | 1118 patients | 1574 patients | CNN showed significantly lower sensitivity and higher specificity than radiologists in both internal and external test sets |
Buda et al.22 | 1278 nodules | 99 nodules | N/A | CNN showed significantly higher specificity than inexperienced radiologists who did not use ACR TIRADS |
CNN showed similar AUC, sensitivity, and specificity to expert radiologists on the ACR TIRADS committee | ||||
Kim et al.24 | Commercially available CAD | 218 nodules ≥ 5 mm | N/A | CNN showed significantly lower specificity and AUC than radiologists with comparable sensitivity |
Park et al.20 | 4919 nodules ≥ 5 mm | 286 nodules ≥ 5 mm | N/A | No significant difference in diagnostic performance between the CNN and radiologists |
Ko et al.18 | 439 nodules ≥ 1 cm and < 2 cm | 150 nodules ≥ 1 cm and < 2 cm | N/A | No significant difference in diagnostic performance between the CNN and radiologists |
Koh et al.21 | 13,560 nodules ≥ 1 cm | 200 nodules ≥ 1 cm | 600 nodules ≥ 1 cm | CNN showed significantly higher AUC in the internal test set, while no significant difference was shown in the external test sets |
CNN showed significantly lower sensitivity and higher specificity than radiologists in the internal test set and one of the four external test sets | ||||
Han et al.23 | Commercially available CAD | 454 nodules ≥ 1 cm | N/A | CNN showed significantly lower specificity and AUC than radiologists with comparable sensitivity |
