Transrectal ultrasound imaging and prostate cancer

Prostate cancer is one of the most important causes of death from cancer in men. Ultrasound imaging is frequently used in the diagnosis of prostate cancer. This paper presents an overview of currently available ultrasound imaging techniques. The underlying principles and methods are discussed briefly and examples of the clinical application are presented. Techniques such as gray-scale imaging, Doppler imaging and contrast enhanced imaging techniques using power Doppler, color Doppler, harmonic imaging and intermittent imaging are discussed.
