Evaluation of the 29 MHz Micro-Ultrasound Imaging for Prostate Cancer Diagnosis and Treatment

We describe our experience with four patients undergoing cryotherapy for treatment of prostate cancer. Micro-ultrasound was utilized in conjunction with standard transrectal ultrasound to intraoperatively assess lesions. In addition, the results were compared to preoperative mpMRI in several patients. The use of micro-ultrasound has been evaluated in clinical trials to include real-time imaging in the clinic for biopsies and fusion with prior mpMRI. We evaluated the technique in men with known prostate cancer undergoing cryoablation. Micro-ultrasound has the potential to replace the current clinical methods for targeted prostate biopsies and improve intraoperative monitoring.
