Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to find out how best to detect clinically significant lesions of prostate cancer by using micro-ultrasound technology (ExactVu) and by multiparametric magnetic-resonance imaging (mpMRI).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a pilot clinical trial with 30 patients with either: 1) suspected prostate cancer (based on elevated PSA or abnormal digital rectal exam (DRE), or 2) known low-risk prostate cancer being managed with active surveillance.

Enrolled patients will undergo MRI fusion biopsy and standard-template 12 core TRUS biopsy as the standard-of-care. Patients will also undergo micro-ultrasound evaluation and targeted biopsy if lesions are identified. Detection rates of clinically significant lesions by ExactVu and by MRI will be compared.

Standard of Care Biopsy

Patients will be evaluated with multiparametric MRI prostate followed by ExactVu micro-ultrasound to identify target lesions all of which will be biopsied by the examiner

Intervention Type PROCEDURE

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Patients scheduled to undergo biopsy and with one of the following:

* Men with suspicion of prostate cancer
* Men on active surveillance
2. Age ≥18 \[30\]
3. Have available multiparametric prostate MRI
4. Able to provide written, informed consent
5. No significant medical illness which in the opinion of the Investigator would preclude entry to study procedures
6. Be willing and able to comply with scheduled visits

Exclusion Criteria

1. Previously confirmed prostate cancer diagnosis with Grade Group \>= 2
2. Unable to undergo prostate biopsy
3. Prostate MRI unable to be evaluated using the PI-RADS v2 criteria
4. Men with contraindication for MRI or a prostate biopsy
5. Prostate biopsy within 8 weeks prior to mpMRI.
6. Any history of prostate treatment
