Examples of DL-CAD diagnosis using f-DWI (a) and z-DWI (b). The red or orange ROIs indicate highly suspected PCa lesions detected by the system. Cases without ROIs indicate no suspected PCa lesion was detected. Case 1. A 77-year-old man with an inflammatory lesion in the central zone (CZ). DL-CAD using f-DWI detected a fake cancer lesion in PZ, which was a rectal artifact. Case 2. A 62-year-old man with a PCa lesion (Gs = 3 + 4) in the right PZ, which was missed by DL-CAD with the use of f-DWI possibly due to rectal distortion and artifacts. Case 3. A 71-year-old man with an inflammatory lesion in the right PZ, which was detected by DL-CAD using z-DWI. Case 4. A 73-year-old man with a PCa lesion (Gs = 4 + 3) in the transition zone (TZ) which was missed by DL-CAD using z-DWI
