MRI Guided Prostate Biopsy

December 1, 2025 updated by: Kemal Tuncali, M.D., Brigham and Women's Hospital

Magnetic Resonance Imaging Guided Prostate Biopsy

This study aims to assess the feasibility of magnetic resonance (MR) guided prostate biopsy using a needle holder frame. This frame is used to help position the needle used for the biopsy. The feasibility in this study is defined as whether the needle holder frame enables accurate tissue sampling from a suspicious region in the prostate found on an MR image. If it does, a biopsy can be carried out with the needle holder frame safely in a clinical routine. The study will be conducted during a routine MR-guided prostate biopsy procedure with an investigational needle holder frame instead of a conventional needle-guiding template.

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.

Detailed Description

The study will be conducted during a routine MR-guided prostate biopsy procedure. The following protocol follows the workflow of the routine procedure, except that the needle holder frame is used in place of a conventional needle-guiding template. The treating physicians have decided that an MR-guided prostate biopsy is necessary under the participant's current condition. If the participant chooses to participate in this research study, the procedure will be done in an MR scanner with an investigational needle holder frame.

Before the MR-guided prostate biopsy, the participant already had a standard clinical prostate MRI, the images from which will be used during the procedure.

The MR-guided prostate biopsy procedure may require monitored anesthesia or sedation. The participant will meet with the study physician prior to the biopsy procedure. The study physician will decide the type of monitored anesthesia or sedation to be used in discussion with the participant.

When undergoing a study in the MRI system, the participant will lie motionless inside the gantry of the system. Occasionally, the machine will produce a loud banging noise, as if it were being pounded from the outside with a hammer. Earplugs are available to reduce this sound level.

While the participant is in the magnet, under the anesthetic, the study physician will do the biopsy. To do this, the study physician will use a needle holder frame, which will show us where to put the needle by lining up the correct place outside on the skin or rectal wall.

Like the routine procedure, the biopsy is done with a needle put through the skin under the participant's scrotum by the doctor. The location of the needle is confirmed by acquiring an MR image (confirmation image). Several biopsies are taken each time, from either side of the gland and from places where the MR images show shadows or abnormal areas. There can be a range of 6-15 locations to sample. Because the location of the needle is always confirmed on the confirmation image, like the routine procedure, the use of the needle holder frame will not compromise the sampling of MR-indicated abnormal areas. The participant will be in the study for about 1.5 hours, which is how long the biopsy procedure will take. After the procedure, the investigator will review the confirmation images to assess the accuracy of needle placement, though it will not change the health outcome (e.g., pathological findings).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Either an abnormal serum prostate-specific antigen (PSA) level (> 4ng/Ml) or a palpable nodule in the prostate on digital rectal examination or prostate MRI suspicious lesion..
  • Diagnostic MRI of the prostate gland.
  • Age > 30 years
  • Signed informed consent.
  • No contra-indications to MRI, i.e. no cardiac pacemaker.
  • No recent or ongoing active ischemic heart disease.

Exclusion Criteria:

  • Inability to give informed consent.

Experimental: MRI-guided prostate biopsy
Participants who receive biopsy under MRI-guidance and a needle holder frame.
Device: MRI-guided prostate biopsy using the needle holder frame.
A needle holding frame will be used during a routine MRI-guided prostate biopsy procedure, where tissue samples are obtained from each suspected region found on MRI using an MRI-conditional core biopsy needle. In this routine procedure, tissue sampling is performed in an MRI gantry and intraprocedural MRI is used to localize the regions.
