Images in a 64-year-old male patient who underwent MRI for clinical suspicion of prostate cancer

Caption

Images in a 64-year-old male patient who underwent MRI for clinical suspicion of prostate cancer (external test set). The patient was subsequently diagnosed with clinically significant prostate cancer in the left anterior transition zone at the base of the prostate gland. The model’s output (patient-level probability) was 0.97. The radiologist graded this examination as Prostate Imaging Reporting and Data System 3 for the left lobe lesion. (A) T2-weighted image (representative section). (B) Apparent diffusion coefficient map (representative section, left) and high-b-value diffusion-weighted image (representative section, right). (C) T1 dynamic contrast-enhanced images (representative sections). (D) Volumetric composite of T2-weighted images (rows 1 and 2), diffusion-weighted images (rows 3 and 5), and apparent diffusion coefficient maps (row 4), with superimposed gradient-weighted class activation maps (rows 2 and 5). All images are in the transverse plane.
