The next generation of prostate care

Targeted MR/ultrasound biopsy is poised to become a new standard in prostate care. The UroNav Fusion Biopsy System from Invivo fuses pre-biopsy MR images of the prostate with ultrasound-guided biopsy images in real time, for excellent delineation of the prostate and suspicious lesions, as well as clear visualization of the biopsy needle.


The traditional approach

Current methods of prostate cancer screening, such as prostate-specific antigen (PSA) tests and digital rectal exams (DRE), are somewhat unreliable and can lead to many uncertainties for both patient and urologist. Prostate biopsy, the most reliable method of detection, is a challenge because of the difficulties in visualizing not only the entirety of the prostate, but also the location of the biopsy needle. Trans-rectal ultrasound-guided prostate biopsy (TRUS), the current biopsy standard, commonly suffers from poor image resolution, and the biopsy needle often passes through tumor-free areas of the prostate - potentially missing the tumor entirely.

A better way

UroNav brings the power of MRI to the Urology suite as prostate and lesion segmentation data from Radiology are quickly and easily transferred to UroNav for review and target identification. This critical exchange of diagnostic information fosters enhanced collaboration between Radiology and Urology in the assessment and biopsy of suspicious prostate lesions.

We work how you work

With UroNav, there is no need for complex mechanical devices or complicated, time-consuming setup routines. UroNav keeps the targeted MR/ultrasound biopsy procedure in your hands with a simple workflow and unique features designed around you and your clinical needs.

A small, electromagnetic navigation sensor attaches to your existing ultrasound transducer. Simply position the tracking and navigation system above the patient and you’re ready to take advantage of UroNav’s simple, guided workflow, which follows the same TRUS biopsy procedure that you are used to.

Transrectal or transperineal – We have you covered from every angle

UroNav supports both transperineal and transrectal biopsy approaches - providing the flexibility necessary to incorporate fusion-guided biopsy into your preferred biopsy method. When UroNav is used in combination with the UroNav mobile stepper system and two navigation sensors, the system will automatically detect that a transperineal biopsy approach is being initiated. UroNav then presents an intuitive, guided workflow and interface optimized to support a transperineal biopsy.

No MRI?  No problem.

The new ultrasound-only workflow allows for tracking of biopsy locations under ultrasound guidance without an MRI.  Biopsy locations can be registered with a future MRI and then targeted for resampling.  Ultrasound-only procedure data, including biopsy location data, can be exported to DynaCAD Prostate for further review and analysis.

Current/Prior fusion workflow

UroNav automatically copies biopsy locations from prior procedures as references into the current MR fusion biopsy procedure. UroNav allows for review and adjustment of the prior-to-current registration, including an optional image-based elastic deformation.  Additionally, UroNav allows new targets to be added on-the-fly based on the locations of prior biopsies.
