PURPOSE: To compare sonoelasticity imaging versus ultrasound (US) in detection of prostate cancer. MATERIALS AND METHODS: Sonoelasticity and US were performed on 10 prostatectomy specimens which cancer was detected at previous biopsy. Six patients had no palpable lesions digital rectal examination. Specimens imaged axially the apex, middle, base gland to correlate with location pathologic sections. All images interpreted blindly prospectively, results compared findings. RESULTS: Sensitivity specificity 85% 84%, respectively, 30% 100% standard when Sixty-four percent pathologically confirmed tumors isoechoic conventional images. CONCLUSION: In this limited study, more sensitive for tumor accurate assessment than US.
