[Innovative approaches in prostate cancer ultrasound].
Today, systematic random biopsies have virtually replaced ultrasound as an imaging tool in the early diagnosis and staging of prostate cancer. Transrectal ultrasonography (TRUS) is now utilized almost only to guide the biopsy needle into the correct anatomical or topographical region of the prostate. Nevertheless, a large number of clinically significant carcinomas are not discovered despite of multiple systematic biopsies. This has led to a dramatic increase in the number of biopsy samples taken, with 6, 10, 12 to 143 being taken during one session depending on the site. Newer modalities and innovative techniques are being investigated in order to accurately identify patients with prostate cancer at different stages of the disease. Innovative ultrasonography techniques may improve the diagnosis and staging of current imaging techniques.
