Description: This algorithm is a deep learning-based computer-aided detection and diagnosis model (Dual-Attention 3D U-Net), which was trained and validated using 1950 prostate bi-parametric (bpMRI) scans paired with PI-RADS v2 annotations. Its intended use is for research purposes only. Its input requires 3 axial/transverse MRI volumes in .mha format:

  1. T2-weighted imaging (T2W)
  2. High b-value diffusion-weighted imaging (HBV)
  3. Apparent diffusion coefficient map (ADC)

In return, the model generates a single, probabilistic heatmap for the likelihood of clinically significant prostate cancer, as its output prediction. While the input images (T2W, HBV, ADC) can be of different spatial resolutions, the algorithm assumes that they are co-registered or aligned reasonably well, and that the prostate gland is localized within a volume of 336 cm³ from their center coordinate.
