background : a transrectal ultrasound-guided prostate biopsy is currently the gold standard procedure to detect prostatic adenocarcinoma. there is little information on the clinical utility of this technique for the detection of prostate adenocarcinoma in men with suspected prostate cancer in pakistan. this study seeks to determine the frequency of prostatic adenocarcinoma by using a transrecta...

At the present time, imaging guided renal biopsy is used to provide diagnoses in most types of primary and secondary renal diseases. It has been claimed that renal biopsy can provide a link between diagnosis of renal disease and its pathological conditions. However, sometimes there is a considerable mismatch between patient renal outcome and pathological findings in renal biopsy. This is the ti...

Early prostate cancers are best detected with transrectal ultrasound (TRUS)-guided core biopsy of the prostate. Due to increased longevity and improved prostate cancer screening, more men are now subjected to TRUS-guided biopsy. To improve the detection rate of early prostate cancer, the current trend is to increase the number of cores obtained. The significant pain associated with the biopsy p...

Background and study aims  Evaluation of longitudinal tumor extent is indispensable for curative surgical treatment of extrahepatic cholangiocarcinoma. The aim of this study was to evaluate the usefulness and feasibility of cholangioscopic-guided mapping biopsy using a newly developed peroral digital cholangioscope, SpyGlass DS (SpyDS), for preoperative evaluation of extrahepatic cholangiocarci...

Background: Diffusion-weighted imaging (DWI) is a main component of multiparametric MRI for prostate cancer detection. Recently, high b value DWI has gained more attention because of its capability for tumor characterization. Objective: To assess based on histopathological findings of transrectal ultrasound (TRUS)-guided prostate biopsy as a reference, an...

Background: To develop a new method for synovial biopsy with ultrasound (US) guidance and a semi-automatic SuperCore biopsy instrument. Materials and Methods: Twenty-two patients (8 men and 14 women, median age 57 years (range 22–79 years)) with active arthritis or tenosynovitis were enrolled from April 2012 through October 2012. Each patient had one joint or tendon biopsied. US examination was...

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...
