Could a simple ultrasound replace MRI for spotting dangerous prostate cancer?
NCT ID NCT06183905
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study compares two imaging methods—multiparametric ultrasound (mpUS) and multiparametric MRI (mpMRI)—to see which better detects clinically significant prostate cancer in men scheduled for their first biopsy. Participants receive both scans before biopsy, and if either shows a suspicious area, targeted biopsies are taken alongside standard systematic samples. The goal is to determine whether the less expensive and more widely available ultrasound can match MRI's accuracy in finding aggressive cancers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Multiparametric ultrasound (mpUS) imaging
- What this could lead to
- If mpUS proves as accurate as MRI, it could offer a faster, cheaper, and more accessible way to detect significant prostate cancer, reducing the need for MRI scans.
- What could go wrong
- Ultrasound may not match MRI's sensitivity, and results depend on operator skill. This is a single-center study, so findings may not apply broadly.

Inclusion Criteria: 1. Scheduled for prostate biopsy; 2. Signed the informed consent. Exclusion Criteria: 1. Contraindications to MRI, such as metal implants, claustrophobia, etc; 2. Contraindications to ultrasound, such as acute myocardial infarction, acute cerebral infarction and rectal tumor after Miles operation; 3. Contraindications of prostate biopsy, such as abnormal routine urine test, coagulation function and electrocardiogram 4. Any medical condition or other event that may significantly reduce the chances of obtaining reliable data, achieving the purpose of the study or completing the study and follow-up; 5. The study doctor thinks it is not suitable to participate in this study.
