Ultrasound and MRI are the two main types of imaging used to aid prostate cancer diagnosis, and the use of multipara metric 3T MRI presents a major advancement in prostate cancer detection and diagnosis because of its superior imaging ability over ultrasound alone. Fusion is a process that blends these technologies to create a detailed, 360° prostate map by merging previously captured MRI images with live TRUS images while the ultrasound wand is inserted.
