Transrectal ultrasound-guided core prostate biopsy is a key event in the diagnosis of prostate cancer, transient side events such as local pain, haematuria, haematospermia, dysuria, and rectal bleeding are reported in a large number of patients. Antimicrobial agents lower the incidence of postbiopsy infectious complications. The timing and duration of the regimen and the route of administration...

Ultrasound elevation beamwidth is the out of plane thickness causing image artefacts normally appearing around anechoic areas in the medium. These artefacts could also cause uncertainties in localizing objects (such as a surgical needle) in the ultrasound image slices. This thesis studies the clinical significance of elevation beamwidth artefacts in needle insertion procedures. A new measuremen...

Abstract Background and study aims Transgastric endoscopic ultrasound (EUS)-guided drainage and, if needed, necrosectomy is the preferred treatment in patients with pancreatic walled-off necrosis. EUS-guided transcolonic or transrectal may serve as a minimally invasive alternative cases which transgastric percutaneous either impossible fails to secure sufficient drainage. In this paper, we retr...

INTRODUCTION Ultrasound-guided transrectal prostatic biopsy is generally a well-tolerated radiological technique with low overall complication ratio. If post-biopsy rectal bleeding occurs, conservative management is effective in the majority of cases. Endoscopic or interventional treatment is rarely required. CASE PRESENTATION We report the case of an 82-year-old white man presenting with mas...

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...

Purpose: Prostate specific antigen levels can be normalized by the prostate volume to give a prostate specific antigen density (PSAd). Magnetic resonance imaging (MRI) can more accurately determine prostate zonal anatomy and prostate volumes compared to transrectal ultrasound, and hence may lead to more accurate PSAd measurements. Methods: Imaging and pathology of men undergoing prostate MRI fr...
