BACKGROUND For patients with an elevated prostate specific antigen (PSA) level or a suspected lesion detected by digital rectal examination, transrectal ultrasound-guided (TRUS) prostate biopsy is the standard procedure for prostate cancer diagnoses. In Taiwan, TRUS prostate biopsy has not been well-studied on a nationwide scale. This article aimed to study TRUS prostate biopsy in Taiwan and it...

BACKGROUND To improve the accuracy of ultrasound-guided biopsy of the prostate, the non-rigid registration of magnetic resonance (MR) images onto transrectal ultrasound (TRUS) images has gained increasing attention. Mutual information (MI) is a widely used similarity criterion in MR-TRUS image registration. However, the use of MI has been challenged because of intensity distortion, noise and do...

Methods 56 patients (pat.) with mostly at least one prior negative TRUS-guided biopsy and persistent suspicion of PCa with at least one mpMRI-defined identifiable cancer suspicious lesion were included in this study between 2012 and 2013. MpMRI: 1.5 T/e-coil/T2WI/DWI, b-values 2012: 0-1500, 2013: 100-1500/DCE-MRI]. MRGB: inbore. Characteristics of lesions (ADC, ESUR PIRADS) were statistically c...

Background/Aim: The aim of this study was to evaluate the cancer detection rate (CDR) using magnetic resonance imaging-transrectal ultrasound (MRI-TRUS) fusion-guided transperineal targeted biopsy (TB). Patients and Methods: We included 401 consecutive patients, which 161 were biopsy-naïve. All underwent prebiopsy bi-parametric MRI; patients with positive MRI [prostate imaging reporting data sy...

Prostate segmentation in trans rectal ultrasound (TRUS) and magnetic resonance images (MRI) facilitates volume estimation, multi-modal image registration, surgical planing and image guided prostate biopsies. The objective of this thesis is to develop shape and region prior deformable models for accurate, robust and computationally efficient prostate segmentation in TRUS and MRI images. Primary ...

PURPOSE To evaluate the feasibility of the use of real-time magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) fusion guided high-dose-rate brachytherapy (HDR-BT) +/- external beam radiation therapy (EBRT) in patients with histologically-proven local relapse after radical prostatectomy. MATERIAL AND METHODS We retrospectively reviewed 13 patients treated with real-time MRI-TRUS fu...

Several reports show increasing incidence of bacterial resistance in patients with sepsis after TRUSguided biopsy.1-3 Preprocedure screening of high-risk patients using cultures from rectal swabs would allow targeted prophylaxis.4,5 We performed a retrospective audit of all men undergoing a TRUS-guided prostate biopsy by one of nine urologists in Newcastle, New South Wales, to assess the incide...

Objective: Transrectal ultrasound (TRUS)-guided prostate biopsy is the standard technique for diagnosing prostate cancer and is one of the most commonly performed procedures by practicing urologists. Despite its widespread use, there are still no universally recognized standards for number of biopsy cores obtained, antibiotic and bowel preparation, or PSA threshold for recommending biopsy. In t...
