Correlation of transrectal ultrasound, computer analysis of transrectal ultrasound and histopathology of radical prostatectomy specimen

[Computer-aided analysis of transrectal ultrasound images of the prostate].

INTRODUCTION Prostate cancer is usually diagnosed by transrectal ultrasound (TRUS) biopsy. Nevertheless, suspicious images are frequently not found. Imaging analysis studies aim to identify ultrasound patterns characteristic of apparently hidden conditions. MATERIAL AND METHODS We digitally recorded 288 TRUS ultrasound guided transrectal biopsies and extracted 3 static images from the punctur...

Transrectal ultrasound-guided percutaneous radical cryosurgical ablation of the prostate.

BACKGROUND The two major treatments for prostate cancer, radical prostatectomy and radiation therapy, are associated with considerable morbidity and variable results. This article presents the preliminary results using percutaneous radical cryosurgical ablation under ultrasound guidance to treat prostate cancer. METHODS The patient group consisted of all patients with localized prostate cance...

Transrectal Ultrasound-guided Prostate Brachytherapy

Framework for 3D TransRectal Ultrasound

Introduction and Objective: Prostate biopsies are mainly performed under 2D TransRectal UltraSound (TRUS) control by sampling the prostate according to a predefined pattern. In case of first biopsies, this pattern follows a random systematic plan. Sometimes, repeat biopsies can be needed to target regions unsampled by previous biopsies or resample critical regions (for example in case of cancer...

Transrectal ultrasound appearances of granulomatous prostatitis.

Granulomatous prostatitis is an unusual, but well-recognized entity frequently mistaken for carcinoma on both digital rectal examination and transrectal ultrasound. The ultrasonographic findings of 11 patients with histologically-proven granulomatous prostatitis are reviewed.
