MRI-guided Prostate Biopsy

Improved accuracy through MRI-supported biopsy
Prior to the actual biopsy, the patient's prostate is first imaged in a multiparametric MRI (mpMRI). This creates a kind of "map" in which areas suspected of being tumorigenic are marked, which we use as a guide when taking tissue samples. The actual biopsy then takes place in a second step under the control of a high-resolution transrectal ultrasound, fusing the MRI map with the ultrasound images. 

The combination of both methods allows a higher degree of diagnostic accuracy to be achieved. As current studies show, the detection rate of 41 percent for prostate carcinoma in an MRI-guided biopsy after tissue removal is significantly higher than the 10 to 20 percent for a biopsy under transrectal ultrasound alone.

A further advantage is that the treatment can be highly targeted by precisely determining both the localization and the aggressiveness of the individual tumor foci in the prostate. Especially for modern therapies, such as brachytherapy, in which not the entire prostate is removed, but rather irradiated with pinpoint accuracy, the MRI-supported biopsy provides valuable additional information.
