Objective: To determine the sensitivity and specificity of detecting prostate cancer by TRUS when compared to histopathology report. Subjects and Methods: This cross-sectional analytical study was carried out within six months from October 2010 to March 2011 in the Department of Radiology/Histopathology, Shaikh Zayed Hospital Lahore. One hundred and ten patients, age above 40 years having abnor...
AIM To explore the potential of transrectal magnetic resonance image- (MRI-) guided biopsies of the prostate in a patient cohort with prior negative ultrasound guided biopsies. PATIENTS AND METHODS Ninety-six men with suspected prostate cancer underwent MRI-guided prostate biopsies under real-time imaging control in supine position. RESULTS Adenocarcinoma of the prostate was detected in 39 ...
Realistic medical procedure simulators improve the learning curve of the clinicians if they can reproduce real conditions and use. This paper describes the improvement of a transrectal ultrasound guided prostate biopsy simulator by adding the simulation of real-time prostate movements and deformations. A discrete bio-mechanical model is used to modify a 3D texture of an ultrasound image volume ...
OBJECTIVE: To determine the role of transrectal ultrasound, especially in association with color Doppler, in the diagnosis of prostate cancer. MATERIALS AND METHODS: Eighty-four cases of patients who underwent transrectal biopsy were prospectively analyzed. In all patients, besides the traditional gray-scale sonogram, color Doppler study was performed in search of hypervascular foci. The result...
OBJECTIVES To determine how high-resolution transrectal ultrasound (HiTRUS) compares with conventional TRUS (LoTRUS) for the visualization of prostate cancer. METHODS AND MATERIALS Twenty-five men with known prostate cancer scheduled for radical prostatectomy were preoperatively imaged with both LoTRUS (5MHz) and HiTRUS (21MHz). Dynamic cine loops and still images for each modality were saved...
