Endourethral MRI Guidance for Prostatic RF Ablation

Abstract

Prostate cancer constitutes a major health problem. Although the medical techniques currently in use to diagnose prostate cancer are successful, the methods to stage the cancer and visualize the invasion and spread of the cancer are inadequate. MRI is known to be the best method for staging but it does not offer image resolution that is acceptable, especially for detecting disease in the anterior prostate. In the first year of the project, we have developed a phased array coil setup that enabled us imaging of the prostate with 160 microns image resolution. The second year, we have developed a mechanical setup that enabled placement of the needles in the prostate with 1mm accuracy. Both of these are published in high impact journals. Developed methods for imaging temperature changes in the prostate with high accuracy. In the last year of the project, we will test the performance of this setup on animals in precise RF ablation of the prostate.
