About 10 years ago, I had an MRI/Ultrasound fusion biopsy done at the National Institutes of Health under a study developing this technology. The hope was that it could not only improve the detection of prostate cancer from the archaic random sampling method, but eventually lead to effective non-invasive testing. This newer study of the results shows that the technology is improving. There is also an indication that the technology may help focal therapy techniques to avoid the radical and sometimes unnecessary major surgery to completely remove the prostate.
Among men undergoing biopsy for suspected prostate cancer, targeted MR/ultrasound fusion biopsy, compared with standard extended-sextant ultrasound-guided biopsy, was associated with increased detection of high-risk prostate cancer and decreased detection of low-risk prostate cancer. Future studies will be needed to assess the ultimate clinical implications of targeted biopsy. “
