New imaging technologies involving MRI are emerging that are helping urologists more accurately target prostate cancer lesions in men diagnosed with prostate cancer. Over the past couple of years MRIs have become more refined, allowing for more accurate diagnoses of malignant tumors. Now, MRI is able to be fused with other new devices with real-time imaging produced by ultrasound. As a result, doctors are able to perform a biopsy with direct guidance of the needle to the suspicious lesion. The procedure is called a fusion biopsy.
