New quick MRI could slash prostate cancer scan costs by 30%
NCT ID NCT05046782
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to test an abbreviated MRI method (using restriction spectrum imaging plus T2-weighted images) for detecting prostate cancer, comparing it to the standard multiparametric MRI. The goal was to see if the faster, cheaper scan could find cancer just as well, while avoiding contrast dye and reducing scan time and cost. However, the study was withdrawn before any participants were enrolled, so no results were obtained.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- restriction spectrum imaging (RSI) MRI device
- What this could lead to
- If successful, this could provide a faster, cheaper, and safer MRI option for prostate cancer detection, reducing scan time and cost by up to 40%.
- What could go wrong
- The study was withdrawn before enrolling any participants, so no results are available. The approach may not prove as accurate as standard MRI in practice.

-Inclusion Criteria: Primary Objective Cohort * Treatment naïve patients with histologically confirmed clinically significant prostate cancer (defined as Gleason score \> 3+4 and a maximum cancer core length of \> 4mm (42)) with a clinical indication for prostate mpMRI for pre-treatment tumor detection and staging * Patients with anticipated clinical follow-up who are anticipated to undergo surgery at MD Anderson. Secondary Objective Cohort * Treatment naïve patients with histologically confirmed intermediate risk prostate cancer (defined as Gleason score \> 3+4 and a maximum cancer core length of \> 4mm (42)) with a clinical indication for prostate mpMRI, who are to undergo target selection for fusion guided biopsy. * Patients who are anticipated to undergo fusion guided biopsy at MD Anderson. Exclusion Criteria: * Patients who have already received androgen deprivation therapy or undergone prior surgery, radiotherapy or focal ablative therapies to the prostate * Patients whose weight exceeds 400 pounds * Patients allergic to gadolinium * Patients with pacemakers or other implantable devices or conditions that are a contraindication to MRI * Patients with conditions precluding MR imaging at 3T * Patients less than 18 years of age * Patients unable to provide informed consent * Patients unable to tolerate an endorectal coil * Patients who have undergone prostate biopsy less than 6 weeks prior to their MRI
