A Pilot Trial Using BR55 Ultrasound Contrast Agent in the Assessment of Prostate Cancer

Ultrasound is a diagnostic imaging test widely used to diagnose many diseases in the body. A rectal ultrasound examination is a safe and routinely used diagnostic method which images the prostate through the rectum. BR55 is a new experimental ultrasound contrast agent. BR55 has been developed for use as a contrast agent to make the images created using ultrasound equipment clearer to see and understand. The purpose of this research study is to demonstrate whether an ultrasound with BR55 will make any lesions in the prostate more visible.
