PURPOSE: To determine if 'saturation' of the index-lesion during MRI-TRUS fusion-guided (fusion) biopsy decreases rate of pathological upgrade from biopsy to radical-prostatectomy (RP). MATERIALS/METHODS: A prospectively maintained single institution database was analyzed for patients who underwent both fusion and systematic biopsy followed by RP (2010-16). Index-lesion was defined as lesion with largest diameter on T2W-MRI. Patients with saturation of the index-lesion (SIL) had transrectal fusion biopsy targets obtained at 6mm intervals along the long axis of index-lesion; patients with nonsaturation of the index-lesion (NSIL) had only one target obtained from the lesion...

PURPOSE: The purpose of this study was to evaluate (18)F-FACBC PET/CT, PET/MRI, and multiparametric MRI (mpMRI) in detection of primary prostate cancer (PCa). METHODS: Twenty-six men with histologically confirmed PCa underwent PET/CT immediately after injection of 369 ± 10 MBq (18)F-FACBC (fluciclovine) followed by PET/MRI started 55 ± 7 min from injection. Maximum standardized uptake values (SUVmax) were measured for both hybrid PET acquisitions. A separate mpMRI was acquired within a week of the PET scans...

PURPOSE: To evaluate the negative predictive value (NPV) of a negative prostate multi-parametric magnetic resonance imaging (mpMRI) in ruling out clinically significant prostate upon 12-core systematic biopsy. METHODS: We retrospectively reviewed 114 men evaluated at our institution who underwent systematic 12-core biopsy within 1 year of a negative prostate mpMRI. Clinicopathologic features were evaluated and NPV was calculated for detection of clinically significant (Gleason ≥ 7) cancer...

RATIONALE AND OBJECTIVES: This study aimed to assess a novel method of three-dimensional (3D) co-registration of prostate magnetic resonance imaging (MRI) examinations performed before and after prostate cancer focal therapy. MATERIALS AND METHODS: We developed a software platform for automatic 3D deformable co-registration of prostate MRI at different time points and applied this method to 10 patients who underwent focal ablative therapy. MRI examinations were performed preoperatively, as well as 1 week and 6 months post treatment...

PURPOSE: To evaluate the role of 3T-MRI-guided adaptive high-dose-rate (HDR) combined intracavitary and interstitial brachytherapy for cervical cancer using a novel intracavitary split-ring (ICSR) applicator adapter. METHODS AND MATERIALS: We retrospectively reviewed all HDR brachytherapy cases from 2013 to 2015 using an ICSR applicator. Initial optimization was performed using 3T multiparametric MRI (mpMRI) series with an applicator in place. The mpMRI series were discretionarily acquired before subsequent fractions for possible target adaptation...

OBJECTIVE: To describe the technique of transrectal biopsy with a new device that fuses multiparametric magnetic resonance (mpMRI) and ultrasound images in real time to guide target biopsies and to evaluate our initial experience. METHODS: Patients with persistent suspicion of prostate cancer despite a previous negative biopsy and who had an mpMRI before the biopsy were selected. All patients underwent target biopsy plus standard systematic biopsy. Significant prostate cancer (sig PCa) was defined according to the Epstein criteria for standard biopsy and Gleason grade of >7 and a positive core length of >5 mm for target biopsy...

OBJECTIVE: To provide insights into the role of mpMRI for predicting oncological control following two focal ablation (FA) templates for selective cases of prostate cancer (PCa). MATERIALS AND METHODS: 59 radical prostatectomies were performed between 2012 and 2016 on cases that fulfilled criteria for FA. The Gleason score (GS), extent of Gleason pattern (GP) 4, maximum linear cross sectional length (MLCSL) and location of tumor foci were recorded and related to scale on corresponding 3mm transverse slice prostate maps...

INTRODUCTION: The classical pathway for the diagnosis of prostate cancer is transrectal ultrasound-guided (TRUS) biopsy of the prostate initiated on the basis of a raised prostate-specific antigen (PSA). An alternative pathway is to perform multi-parametricMRI (MPMRI) to localise cancer and to use this information to influence the decision for, and conduct of, a subsequent biopsy, known as an MPMRI-targeted biopsy. An MPMRI pathway has been shown to detect a similar or greater amount of clinically significant cancer as TRUS biopsy but has several advantages, including the potential to biopsy fewer men with fewer cores...

OBJECTIVES: To analyse the detection rates of primary MRI-fusion transperineal prostate biopsy using combined targeted and systematic core distribution in three tertiary referral centres. PATIENTS AND METHODS: Multicentre, prospective outcome study of 807 consecutive biopsy-naïve patients having undergone MRI-guided transperineal prostate biopsy as the first diagnostic intervention between 10/2012 and 05/2016. MRI was reported following PI-RADS criteria. 236 patients had 18-24 systematic transperineal biopsies only, and 571 patients underwent additional targeted biopsies either by MRI-fusion or cognitive targeting if PI-RADS ≥3 lesions were present...
