A new deep learning model, PSNet, analyzes micro-ultrasound power spectrums to detect prostate cancer. Combining PSNet with PSA measurements significantly improves diagnostic accuracy for clinically significant prostate cancer.

Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Oncology

Background:

  • Micro-ultrasound (micro-US) offers high-resolution imaging for prostate biopsies.
  • Interpreting micro-US images during live biopsies presents a significant challenge.

Purpose of the Study:

  • Develop a convolutional neural network (CNN) to classify prostate tissues from micro-US power spectrums (PS).
  • Distinguish between benign tissues and clinically significant prostate cancer (csPCa).
  • Create a tool for automated interpretation during image-guided prostate biopsies.

Main Methods:

  • A custom CNN, PSNet, was developed using retrospective micro-US data from 491 men.
  • PS were derived from raw micro-US data, avoiding prostate segmentation.
  • Model performance was evaluated against traditional CNNs using B-mode images, with histopathology as the ground truth.

Detection and Isolation of Cancer in Prostate Biopsies Using Stimulated Raman Histology and Artificial Intelligence

Published on: June 10, 2025

Main Results:

  • PSNet achieved an ROC-AUC of 82% for classifying benign vs. csPCa from PS alone.
  • Incorporating prostate-specific antigen (PSA) improved ROC-AUC to 85% at the frame level.
  • At the patient level, PSNet with PSA achieved a high ROC-AUC of 91% and specificity of 99%.

Conclusions:

  • Deep learning can identify prostate cancer from micro-US acoustic properties without segmentation.
  • PSA measurements enhance the diagnostic value of micro-US data, particularly specificity.
  • This approach shows potential for guiding targeted prostate biopsies more effectively.
