Prostate Imaging & Biopsy

Ultrasound Anatomy of the Prostate

Sectional View

Ultrasound Examination of the Prostate: Transrectal ultrasound (TRUS) of the prostate is the standard method used to examine and biopsy a prostate.

See All Sections of the Prostate: Precise biopsies largely depend on how the prostate is presented in the ultrasound image. This is why BK Medical created triplane imaging and developed the simultaneous biplane technique.

Triplane: Triplane combines simultaneous biplane and endfire in one transducer.

Transverse Section

Simultaneous Biplane: Real-time images of the prostate in both the sagittal and transverse planes. If you see the prostate in two planes, it’s easier to target the sections you need for biopsies.

Endfire: For biopsies close to the apex of the prostate, an endfire view and a biopsy guide designed for use in endfire view are ideal for precise, safe biopsies.

Triplane: Triplane combines simultaneous biplane and endfire in one transducer.

Triplane Imaging

With the Prostate Triplane Transducer E14C4t or 8818, you can easily switch between imaging views and choose the biopsy imaging technique you need. The Prostate Triplane transducer supports simultaneous biplane and endfire imaging.

Biplane Imaging

See the prostate in both the sagittal and transverse planes simultaneously with the Prostate Biplane Transducer 8808e. Sterile single-use needle guides are available for the prostate biplane transducer.

Endfire Imaging

Endfire imaging for apical biopsies with the Endfire Curved Array Transducer 8667, Endovaginal Transducer 8819, Endocavity E10C4, or the high-resolution Endfire E13C2 transducer.  Sterile, single-use needle guides are available*.

Transrectal and Transperineal Biopsies

For more than 25 years, PSA testing and transrectal ultrasound-guided prostate biopsy (TRUS-Bx) has been the primary diagnostic pathway for prostate cancer. Advances in diagnostic imaging and TRUS-guided biopsy techniques have the potential for more accurate localization of cancers within the prostate, and there is growing interest in the concept of focal therapies driven by downward stage migration, improved biopsy and imaging techniques, and the prevalence of unifocal dominant cancers.

Transperineal biopsies (TPUS Bx) offer a systematic and targeted method for diagnosing prostate cancer in some patients. Transperineal biopsies enable you to target and sample the whole of the peripheral zone, where 96% of cancers develop.

* Sterile, single-use needle guides for the endfire curved array transducer are only available in EU countries.
