Definition

A biopsy procedure that combines the pictures from an MRI scan and an ultrasound to create a detailed 3-D image of the prostate. This procedure makes it easier to see an abnormal area of tissue in order to guide the biopsy needle into the abnormal area. A sample of tissue can then be removed and checked under a microscope for signs of cancer. A fusion biopsy may help find prostate cancer cells that may be missed with other types of biopsies. It may help find cancer at an early stage and plan cancer treatment. Also called MRI ultrasound fusion-guided biopsy.
