Computer-aided diagnosis with a convolutional neural network algorithm for automated detection of urinary tract stones on plain X-ray

Table 2 The accuracy of the model for each urinary tract stone location

Urinary tract stone location	Number of TP	Number of FP	Number of FN	Sensitivity	PPV
Kidney	95	72	11	0.896	0.569
Proximal ureter	99	14	8	0.925	0.876
Mid-ureter	13	13	9	0.591	0.500
Distal ureter	24	19	6	0.800	0.558
All locations	231	118	34	0.872	0.662

TP true positive, FP false positive, FN false negative, PPV positive predictive value
