Target localization in MRI-guided prostate biopsy
Prostate cancer is a worldwide health concern for men. Needle biopsy is the most definitive form of cancer diagnosis. Target-specific biopsies can be performed under magnetic resonance imaging (MRI) guidance. However, needle placements are often inaccurate due to intra-operative prostate motion and …

The experiences of men receiving results of a prostate biopsy: a service evaluation
… enables men to telephone for the result of their prostate biopsy. The service has evolved over time initiated by patients need to know quickly whether or not they have cancer. Current guidance recommends that a cancer diagnosis should be explained face to face. Evaluation of the service in 2007 by …

A 3-D Multiparametric Ultrasound Elasticity Imaging System for Targeted Prostate Biopsy Guidance
<p>Prostate cancer is the most common cancer and second-leading cause of cancer death among men in the United States. Early and accurate diagnosis of prostate cancer remains challenging; following an abnormal rectal exam or elevated levels of prostate-specific antigen in serum, clinical guidelines …

The accuracy of prostate biopsy to assign patients with low-grade prostate cancer to active surveillance
PURPOSE: To determine the accuracy of prostate biopsy Gleason score (GS) compared to prostatectomy GS. To determine whether a biopsy is a satisfactory diagnostic procedure to offer active surveillance for patients with low-grade prostate cancer. METHODS: This study was conducted in Tuft Medical …

Risk Factors for Acute Prostatitis after Transrectal Biopsy of the Prostate
… with acute prostatitis after transrectal prostate biopsy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 923 transrectal ultrasound-guided needle biopsy of the prostate on 878 patients performed in our institution from June 2004 to May 2009. The indications for …

A review of transrectal ultrasound guided prostate biopsies is there still a role for finger-guided prostate biopsies?
Prostate cancer is the most common male malignancy amongst black males in South Africa and the second commonest amongst white males (1,2). Prostate biopsy, via the rectum, is an essential part of diagnosing and treating this disease. Traditionally needle biopsies of the prostate were performed …

Electrical Impedance Spectroscopy with Multi-modal Tissue Discrimination for Ultrasound-Guided Targeted Biopsy
Prostate cancer diagnosis has undergone considerable evolution in recent years. Men with significant lesions observed via magnetic resonance imaging (MRI) typically undergo targeted biopsy. In a prostate biopsy procedure, ultrasound (US) is used to place a biopsy needle in lesion(s) identified via …

Evaluating Human Performance for Image-Guided Surgical Tasks
… for two different interventional tasks; targeted prostate biopsy tasks using a tracked biopsy device, and external ventricular drain placement tasks using a mobile-based augmented reality device for visualization and guidance. In both tasks, a human performance methodology was utilized which …

Does the use of video improve patient satisfaction in the consent process for local-anaesthetic urological procedures?
… recruitment: flexible cystoscopy with or without biopsy, transrectal ultrasound-guided prostate biopsy or flexible cystoscopy with insertion or removal of a ureteric stent. Audio-visual media were developed for each procedure, with each script translated from English into isiXhosa and Afrikaans. …

Hospitalization Itself Decreases the Serum Prostate-specific Antigen Values Compared to the Outpatient Values in Patients with Benign Prostatic Diseases
… AND METHODS: Transrectal ultrasound-guided prostate biopsies were performed for detecting prostate cancer in 2,017 patients between February 2001 and April 2011 at our institution. Among them, 416 patients who were hospitalized for prostate biopsies, whose serum PSA values were checked at …

A Retrospective Audit Of Biojet® Prostate Fusion Biopsies Amongst Patients Seen In A High-Volume Private Referral Centre In Cape Town Between January 2017 And April 2020
Introduction: The field of prostate cancer has seen a dramatic change in its approach to diagnosis, from the advent of PSA in the 1980s to the transrectal ultrasound guided 12 core biopsies with a false negative rate of approximately 30%. Recent advances in this field involve fusing MRI images with …

Detection of prostate cancer using multi-parametric magnetic resonance
A multi-channel statistical classifier to detect prostate cancer was developed by combining information from 3 different MR methodologies: T2-weighted, T2-mapping, and Line Scan Diffusion lmaging(LSDI). From these MR sequences, 4 sets of image intensities were obtained: T2-weighted(T2W) from …

Obesity and Aggressive Prostate Cancer: Bias and Biology
… metabolic and sex steroid hormones involved in prostate development as well as oncogenesis. However, the current observational evidence linking obesity to aggressive PC is inconsistent or conflicting, and there is growing concern that much of the heterogeneity across studies may be the result of …

Retrospective review: diagnostic performance of PI-RADS V2.1 4 and 5 lesions in predicting clinically significant prostate cancer at Groote Schuur Hospital, South Africa
Background: Multiparametric MRI (mpMRI) prostate has become a fundamental part of prostate cancer primary diagnosis, active surveillance, and lesion localization. PI-RADS reporting lexicon is used to report mpMRI prostate examinations and is a risk- adjusted reporting structure designed by the …
