Painless, safe, precise
Transperineal 3D biopsies go hand in hand with MRIs for maximum accuracy. With three times the accuracy of a normal punch biopsy, a 3D biopsy makes it possible to create histology maps of the entire prostate. Because of this, 3D biopsies are not only the method of choice for initial diagnosis or exclusion of a suspected carcinoma, but also essential for planning modern focal therapy.
When and why to do a biopsy
With the enormous technical progress embodied in MRI (Magnetic Resonance Imaging) and the extremely brilliant images it produces nowadays, it may seem strange that tissue samples still have to be taken manually.
Well, in this case, “have to” is relative. As a first step, an MRI is always the most precise and non-invasive method. If the MRI does not show any suspicious zones, a biopsy is usually not worthwhile. But if the MRI images show suspicious zones, more clarification is necessary. Although MRI images provide good information and have the greatest statistical precision of all imaging technologies, an MRI cannot show individual cells.
But exactly this is necessary for two reasons:
- to confirm that it really is a tumor (MRI images only show various degrees of suspicion)
- to grade the tumor, i.e. determine how aggressive it is
A 3D biopsy produces a precise 3D histological map of the prostate that can be represented in various ways. This is an essential tool for a physician in planning focal therapy, but also in reaching a solid therapy decision.
