Figure 3

A 69-year-old man with prostate cancer (A) and a 53-year-old woman with breast cancer (B). The patient with prostate cancer had multiple metastases that were correctly identified by BN2, and the BSI was increased with BN2 compared with EB. The patient with breast cancer did not have metastasis, and both ANN and BSI were reduced by the revised versions with Japanese training databases. Red hot spots denote high-risk lesions, namely high probability of metastases, whereas blue hot spots denote low-risk lesions.
