A one-plane view of the prostate can make it difficult to complete a biopsy regimen because it is not possible to be certain that the intended targets are being sampled. A simultaneous biplane view enables more correctly targeting of the sections for biopsies. For example, simultaneous biplane is excellent for taking biopsies in the peripheral zone of the prostate, where most cancers occur. In older men, the transition zone tissue tends to develop BPH and, by its growth, cause the peripheral zone to become thin and difficult to target. A real-time transverse image, together with a real-time sagittal image, provides a clear indication that the needle in the longitudinal plane is in the correct area, for quicker and more accurate biopsies. This is due to the fact that you can see the same structure in two planes at the same time. The wide sector angle on the Prostate Triplane Transducer 8818 easily accommodates both the right- and left lateral peripheral zone in one image. You cannot get nearly as good orientation to follow a particular biopsy scheme with only a one-plane view.
Why endfire imaging is suitable for apical biopsies
Any biopsy regimen must include at least two biopsies that are from the left and right apical area of the
prostate yet still close to the parasagittal plane. In some patients, however, simultaneous biplane has some
limitations for biopsies in the apical section of the prostate. Because the transducer features transverse and sagittal images, the biopsy channel must permit the biopsy path to be identified in two perpendicular planes. The biopsy channel cannot be placed over one of the transducer arrays when the transducer is set to simultaneous biplane mode, as this would prevent imaging from one of the arrays in that situation.
If you attempt apical biopsies with a dedicated simultaneous biplane biopsy channel, the needle may
end up piercing tissue at a small, but significant distance behind the sagittal image projection.
Examining the anatomy slightly caudal to the apex more closely identifies the puborectalis muscle complex
together with other muscles such as the urethral sphincter and the rectourethalis muscle.
