If a PSA or DRE test detects an abnormality, your doctor may recommend a prostate biopsy. A prostate biopsy can be performed with a standard transrectal ultrasound or a MRI/Ultrasound Fusion Guided Biopsy. Your doctor will discuss which approach is right for you.
- Transrectal ultrasound (TRUS): Using ultrasound images for guidance, the Urologist will remove small samples (biopsy) which are then looked at under a microscope. Most urologists will take about 12 core samples from different parts of the prostate. This is done in the office setting.
- MRI/Ultrasound Fusion Biopsy: The MRI/Ultrasound fusion biopsy begins with a MRI of the prostate. The MRI images are read by a trained Radiologist and abnormal areas are outlined if present. These images from the MRI are fused with the real time ultrasound at the time of the biopsy. Any abnormal areas that have been identified are targeted. In addition to the targeted biopsy, an additional standard sampling of the prostate (12 biopsy cores, as above) will be performed. If no suspicious areas were identified on the MRI, only the standard 12 core transrectal ultrasound-guided non-targeted biopsy will be performed.
