About this study

Official title: Optimization of PCaVision: A Prospective Study for CAD-based Detection of Clinically Significant Prostate Cancer Using mpUS and Contrast Agents

This prospective clinical study aims to retrain and validate the PCaVision AI algorithm for the detection and localization of clinically significant prostate cancer (csPCa) using multiparametric ultrasound (mpUS) with two different ultrasound contrast agents: Sonovue and Optison. Data will be collected using a commercial version of the LOGIQ E10 ultrasound machine, with full histopathological correlation in patients undergoing radical prostatectomy.

Read the detailed description

The PCaVision CAD system was initially developed using Sonovue contrast and a research-only ultrasound machine (LOGIQ E10 R3). In this study, the algorithm will be retrained using data acquired from the LOGIQ E10 R4, a commercially available system, and using both Sonovue and Optison as contrast agents. The goal is to enhance generalizability and enable broader clinical adoption. The study includes two cohorts: patients scheduled for radical prostatectomy (for training and voxel-level validation) and patients with a negative prostate MRI (for patient-level specificity evaluation). All participants will undergo 3D transrectal mpUS with both contrast agents in a single session. Full prostate histology from RP specimens will serve as the reference standard.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity and Specificity of PCaVision Algorithm (Sonovue and Optison) Compared to Histopathology

    Sensitivity and specificity of the PCaVision algorithm in detecting and localizing clinically significant prostate cancer (csPCa, Gleason Grade Group ≥2) at the voxel level, based on 3D multiparametric ultrasound (mpUS) images using Sonovue and Optison, validated against full prostate histology after radical prostatectomy.

    Measured: From baseline imaging to histopathology report (typically within 2-4 weeks post-surgery)

Secondary outcomes (2)
  1. Specificity of PCaVision in MRI-Negative Cohort

    Evaluation of the specificity of the PCaVision algorithm for csPCa detection at the patient level in men with a negative prostate MRI (PI-RADS ≤2), using mpUS imaging with Sonovue and Optison.

    Measured: From baseline imaging to completion of image processing and analysis (within 2 weeks of scan)

  2. Diagnostic Performance Comparison Between Sonovue and Optison

    Head-to-head comparison of diagnostic performance (sensitivity, specificity, AUC) of PCaVision on mpUS scans obtained with Sonovue versus Optison, using RP histopathology as reference. Evaluated at voxel level and using simulated biopsy protocols.

    Measured: Imaging and analysis completed within 4 weeks post-surgery

Individual data sharing
No: Individual participant data (IPD) will not be shared for this study because the imaging data and histopathology are linked to highly sensitive clinical records. Due to privacy concerns and the risk of re-identification, even in coded form, sharing of raw participant-level data is not planned. Data will only be used internally for algorithm development and validation under strict confidentiality agreements.
