: We describe our experience in prostate biopsy using a new standardized cognitive fusion techniques, that we call "cognitive zonal fusion biopsy". This new technique is based on two operative options: the first based on target biopsies, the Cognitive Target Biopsy (CTB) if the same target was detected with transrectal ultrasound (TRUS) and multiparametric magnetic resonance (mpMRI); the second based on saturation biopsies, the Zonal Saturation Biopsy (ZSB) on anatomical zone/s containing the region of interest if the same target was not evident with TRUS and MRI...

For various reasons, prostate cancer is a major public health problem. It is a very common cancer, but has a very low mortality rate because it comprises two types of disease: one insignificant, indolent, and much more common, and the other aggressive, significant, and much less common. The routine diagnostic approach to prostate cancer has been systematic blind biopsies, which has low detection rates and might detect low risk, insignificant prostate cancer, leading to overdiagnosis and overtreatment of indolent cancers...

INTRODUCTION: The recent literature has focussed predominantly on prostate cancer detection which has been revolutionized by multiparametric magnetic resonance imaging (mpMRI). Due to an overlap of features, prostatitis may mimic prostate cancer on MRI, especially in patients with chronic prostatitis. We retrospectively analysed our in-gantry MRI-guided biopsy (MRGB) results to determine incidental detection rate of prostatitis in Prostate Imaging Reporting and Data System (PIRADS) 3, 4 and 5 foci reported on diagnostic MRI of the prostate...

Conventional prostate cancer staging strategies have limited accuracy to define the location, grade, and burden of disease. Evaluations have historically relied upon prostate-specific antigen levels, digital rectal examinations, random systematic biopsies, computed tomography, pelvic lymphadenectomy, or (99m)technetium methylene diphosphonate bone scans. Today, risk-stratification tools incorporate these data in a weighted format to guide management. However, the limitations and potential consequences of their uncertainties are well known...

BACKGROUND: Targeted prostate biopsies are changing the landscape of prostate cancer (PCa) diagnosis with the degree of suspicion on multiparametric magnetic resonance imaging (mpMRI) being a strong predictor of targeted biopsy outcome. Data regarding the rate and potential causes of false-negative magnetic resonance imaging-transrectal ultrasound (MRI-TRUS) fusion-targeted biopsy in patients with highly suspicious mpMRI findings are lacking. OBJECTIVES: To determine the rate of clinically significant PCa detection in repeat targeted biopsy or surgery in patients with highly suspicious mpMRI findings and in an initial negative MRI-TRUS fusion-targeted biopsy...

In recent years, the development of diagnostic methods based on metabolic imaging has been aimed at improving diagnosis of prostate cancer (PCa) and perhaps at improving therapy. Molecular imaging methods can detect specific biological processes that are different when detected within cancer cells relative to those taking place in surrounding normal tissues. Many methods are sensitive to tissue metabolism; among them, positron emission tomography (PET) and magnetic resonance spectroscopic imaging (MRSI) are widely used in clinical practice and clinical research...

PURPOSE: Multiparametric MRI (mpMRI) of the prostate is an evolving technology that provides functional information of the prostate that helps distinguish benign from malignant lesions. We hypothesized that mpMRI is rapidly adopted in the US to fill the unmet need for a non-invasive, accurate screening tool. The aim of this study is to assess the increasing utilization of mpMRI for the diagnosis and management of prostate cancer. METHODS: We conducted a retrospective review of an institutional clinical data repository of four million patients...

Multiparametric magnetic resonance (mpMRI) imaging has assumed a larger role in the diagnosis and management of prostate cancer. The current method of detecting prostate cancer relies on blind systematic biopsy, guided only by transrectal ultrasound that generally directs the needle biopsy to sextants of the prostate rather than specific lesions. MpMRI is playing an increasing role in the detection of primary cancer as it can visualize cancers and direct biopsies. However, even mpMRI is inherently nonspecific and numerous biopsies performed under MR guidance prove to be negative...

INTRODUCTION: The utility of T2-weighted magnetic resonance imaging (MRI) in the local staging of prostate cancer is controversial. Due to the success of multiparametric MRI in cancer localization, there is renewed interested in MRI (± functional sequences) for local staging. Guidance on pre-treatment local staging of prostate cancer by MRI was developed using systematic review methodology and expert consultation. METHODS: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and other databases were searched to identify studies comparing: (1) MRI staging vs...
