Transrectal Photoacoustic Imaging of the Prostate
An observational study of Prostate Cancer, run by Stanford University at 1 site in United States.
Trial summary
The purpose of this study is to image human prostate tissue using a new transrectal photoacoustic imaging probe and correlate this with ultrasound and MRI imaging performed once the specimen has been surgically removed. We hope to see what we can visualize with our device as this has never been done before. Read more about this study

About this study
The purpose of this study is to image human prostate tissue using a new transrectal photoacoustic imaging probe and correlate this with ultrasound and MRI imaging performed once the specimen has been surgically removed. We hope to see what we can visualize with our device as this has never been done before. Eventually, we hope to use a similar device to image the prostate in men being seen by their doctor for prostate cancer.

Questions about this trial
What is this clinical trial studying?
An observational study of Prostate Cancer, run by Stanford University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 14 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: PI passed away). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quality of images obtained (time frame: 18 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jun 2022; AzTrials last refreshed its copy on 7 Nov 2026.
