Effect of Bacillus Calmette-Guerin Exposure on Prostate Cancer Detection Using Magnetic Resonance Imaging: A Cohort Study.

Background: Granulomatous prostatitis is a medical condition that may mimic prostate cancer.

Purpose: Granulomatous prostatitis resulting from BCG-exposure can confound the diagnosis of prostate cancer based on prostate imaging and data system (PI-RADS) classification observed on multiparametric prostate magnetic resonance imaging (mpMRI).

Study Type, Population, Assessment And Statistical Tests: A cohort study was conducted, enrolling consecutive males at risk for prostate cancer who underwent an mpMRI-targeted prostate biopsy between February 2016 and August 2023.

Prevalence and grade of malignancy differences with respect to the area of involvement in multiparametric resonance imaging of the prostate in the diagnosis of prostate cancer using the PI-RADS version 2 classification.

Purpose: The peripheral zone is histologically different from the transitional zone. The aim of this study is to analyze the differences between the prevalence and grade of malignancy of mpMRI-targeted biopsies that involve the TZ with respect to the PZ.

Methods: A cross-sectional study of 597 men evaluated for PC screening between February 2016 and October 2022 was conducted.

Comparative study between 1.5 and 3 Tesla multiparametric MRI systems using the PIRADS version 2 classification in the diagnosis of prostate cancer.

Introduction: The 3-Tesla multiparametric MRI (mpMRI) system represents a diagnostic advance for prostate cancer. Our aim is to demonstrate that the results in 1.5-Tesla mpMRI are not inferior compared to the 3-Tesla for the correct diagnosis of prostate cancer.
