[Targeted MRI prostate biopsies]

Prostate cancer is the first cancer and the second cause of cancer death in men in France. It is now a major public health issue, particularly given the increase of life expectancy. If screening is based on blood PSA and clinical examination (DRE), diagnosis requires the histological analysis of prostate samples. In current clinical routine, these biopsies are performed by endorectal through ultrasound guidance. In most cases, the cancer is not visible in the ultrasound image and the latter is used to make a dozen samples (or core), distributed as best as possible in the prostate. To increase the accuracy and the contribution of these biopsies, the use of data acquired by the magnetic resonance imaging (MRI), as well as the fusion of ultrasound and MRI images, is a therapeutic undergoing validation, and today performed in many institutions with dedicated tools. The objective of this work is to present the practical arrangements for the implementation of these biopsies using the image fusion, and discuss the advantages and benefits.
