Results: Training set sensitivity was 0.83 (10 of 12; 95% confidence interval: 0.51, 0.97), with an FPR of 7.4 per patient. Oftentimes, small holes result from osteolysis. These holes in the bone are referred to as osteolytic lesions or lytic lesions. Lytic lesions can weaken the bones and increase the risk of breakage or other problems.
