Utility of Adding MR Fusion to Standard US Guided Prostate Biopsy

November 25, 2025 updated by: University of Arizona

Improved Detection and Localization Accuracy of Early Aggressive Prostate Adenocarcinoma Using Novel MR-directed Ultrasound-guided (MRdUSg) Prostate Biopsy Technique

The purpose of this study is to utilize this technology in the early detection and staging of pathologic states within prostate cancer patients using the information obtained on mpMRI and serum biomarkers from the patient's blood (if collected). Ultimately, investigators hope to improve the diagnostic accuracy and treatment selection process for these patients. Applying the fusion software which adds mpMRI to ultrasound images in real time, to an otherwise clinically standard but non-targeted ultrasound-guided prostate biopsy procedure will help with accurate and early diagnosis of prostate cancer.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult male patients undergoing diagnostic work up for suspected or recurrent prostate cancer as standard of care.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
All subjects
The experimental conditions will include a standard prostate biopsy using an FDA-approved ultrasound machine with application of the experimental (non-FDA approved) image fusion software.
Diagnostic test: TRUS biopsy
The biopsy procedure will be completed using an FDA-approved ultrasound machine with the addition of an investigational (non-FDA approved) image fusion software.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Evaluate investigational fusion software.
Time Frame: Through study completion, planned 5 year duration.
To evaluate the sensitivity of the investigational software to aid in targeted biopsy of prostate lesions seen on pre-biopsy mpMRI.
Through study completion, planned 5 year duration.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assess accuracy of mpMRI.
Time Frame: Through study completion, planned 5 year duration.
To assess the diagnostic accuracy of Multiparametric Magnetic Resonance Imaging (mpMRI) provided Prostate Imaging Reporting and Data System (PIRADS) with pathology as the reference standard. The research-only procedure of collecting blood will be drawn during the scheduled biopsy visit, using no more than 15 minutes when the subject would already be at the visit. TRUS biopsy is standard of care. Experimental software will be added during the TRUS biopsy, at the time of needle localization. The software performs a computation on the ultrasound machine that fuses the pre-biopsy mpMRI images with the real-time ultrasound images.
Through study completion, planned 5 year duration.
Assess sensitivity of software.
Time Frame: Through study completion, planned 5 year duration.
To assess the sensitivity of the investigation software in successfully targeting clinically significant prostate cancer, defined as Gleason score of 3+4 or greater. The research-only procedure of collecting blood will be drawn during the scheduled biopsy visit, using no more than 15 minutes when the subject would already be at the visit. TRUS biopsy is standard of care. Experimental software will be added during the TRUS biopsy, at the time of needle localization. The software performs a computation on the ultrasound machine that fuses the pre-biopsy mpMRI images with the real-time ultrasound images.
Through study completion, planned 5 year duration.
Correlation of imaging with biomarkers.
Time Frame: Through study completion, planned 5 year duration.
To correlate Prostate Imaging Reporting and Data System (PIRADS) score from Multiparametric Magnetic Resonance Imaging (mpMRI) with cellular/ molecular biomarkers of aggressive cancer in the biopsy tissue samples. The research-only procedure of collecting blood will be drawn during the scheduled biopsy visit, using no more than 15 minutes when the subject would already be at the visit. TRUS biopsy is standard of care. Experimental software will be added during the TRUS biopsy, at the time of needle localization. The software performs a computation on the ultrasound machine that fuses the pre-biopsy mpMRI images with the real-time ultrasound images.
Through study completion, planned 5 year duration.
