Hierarchical Image Registration for Improved Sampling during 3T MRI-guided Transperineal Targeted Prostate Biopsy
Introduction Prostate cancer (PCa) is one of the most common cancer types in men in the USA. Diagnosis and staging of PCa relies on the histological analysis of biopsied prostate tissue samples. Joint use of multi-parametric MRI (mpMRI) (T2, DWI, DCE) results in improved detection of prostate cancer, while the use of MRI for biopsy guidance leads to superior accuracy of needle targeting. A chal...
متن کاملNon-rigid MRI-TRUS registration in targeted prostate biopsy
A non-rigid registration method is presented for the alignment of pre-procedural magnetic resonance (MR) images with delineated suspicious regions to intra-procedural 3D transrectal ultrasound (TRUS) images in TRUSguided prostate biopsy. In the first step, 3D MR and TRUS images are aligned rigidly using six pairs of manually identified approximate matching points on the boundary of the prostate...
متن کاملStereotactic transperineal prostate biopsy.
This study investigates the detection rate of nonpalpable, isoechoic occult prostate malignancy using a stereotactic transperineal prostate biopsy (STPB) technique in patients with a previously negative transrectal ultrasound-guided prostate biopsy.
متن کاملEvaluation of MRI/Ultrasound Fusion-Guided Prostate Biopsy Using Transrectal and Transperineal Approaches
Purpose To evaluate transrectal (TR) and transperineal (TP) approaches for MRI/ultrasound (MRI/US) fusion-guided biopsy to detect prostate cancer (PCa). Materials and Methods 154 men underwent multiparametric MRI and MRI/US fusion-guided biopsy between July 2012 and October 2016. 79/154 patients were biopsied with a TR approach and 75/154 with a TP approach. MRI was retrospectively analyzed a...
متن کاملMRI and ultrasound-guided prostate biopsy using soft image fusion.
OBJECTIVES Transrectal ultrasound (TRUS)-guided random biopsies is the gold standard when diagnosing prostate cancer. A new 3D system with organ tracking, allows accurate targeted biopsies using magnetic resonance imaging (MRI) and TRUS soft image fusion. The aim of the study was to evaluate the accuracy of targeted biopsies. MATERIALS AND METHODS Retrospective study of 90 consecutive patient...
