CLINICAL SCIENCE Clinically low-risk prostate cancer: evaluation with transrectal doppler ultrasound and functional magnetic resonance imaging

چکیده
METHODS: From 2005 to 2006, magnetic resonance imaging was performed in 42 patients, and transrectal ultrasound in 26 of these patients. Seven patients were excluded from the study. Mean patient age was 64.94 years and mean serum PSA was 6.05 ng/ml. The examinations were analyzed for tumor identification and location in prostate sextants, detection of extracapsular extension, and seminal vesicle invasion, using surgical pathology findings as the gold standard.

Clinically low‐risk prostate cancer: evaluation with transrectal doppler ultrasound and functional magnetic resonance imaging
OBJECTIVES To evaluate transrectal ultrasound, amplitude Doppler ultrasound, conventional T2-weighted magnetic resonance imaging, spectroscopy and dynamic contrast-enhanced magnetic resonance imaging in localizing and locally staging low-risk prostate cancer. INTRODUCTION Prostate cancer has been diagnosed at earlier stages and the most accepted classification for low-risk prostate cancer is ...
متن کاملMRI-directed cognitive fusion-guided biopsy of the anterior prostate tumors.
PURPOSE We aimed to evaluate the efficacy of magnetic resonance imaging (MRI)-directed cognitive fusion transrectal ultrasonography (TRUS)-guided anterior prostate biopsy for diagnosis of anterior prostate tumors and to illustrate this technique. METHODS A total of 39 patients with previous negative TRUS biopsy, but high clinical suspicion of occult prostate cancer, prospectively underwent pr...
متن کاملMultiparametric magnetic resonance imaging: Current role in prostate cancer management.
Digital rectal examination, serum prostate-specific antigen screening and transrectal ultrasound-guided biopsy are conventionally used as screening, diagnostic and surveillance tools for prostate cancer. However, they have limited sensitivity and specificity. In recent years, the role of multiparametric magnetic resonance imaging has steadily grown, and is now part of the standard clinical mana...
متن کاملMR-Guided Biopsies of the Prostate in Supine Patient Position
Prompted by elevated PSA levels, more than a million men in the United States alone have to undergo transrectal ultrasound (TRUS)-guided prostate biopsy to clarify suspicion for prostate cancer per year [1]. Unlike pathways for other malignancies, biopsy of the prostate is performed by standardized, systematic but essentially random sampling [2]. The major limitation of this approach is that cl...
متن کاملRepeat transrectal ultrasound biopsies with additional targeted cores according to results of functional prostate MRI detects high-risk prostate cancer in patients with previous negative biopsy and increased PSA - a pilot study.
BACKGROUND/AIM Patients with previous negative transrectal ultrasound-guided biopsy (TRUS-GB) and persistently increased prostate-specific antigen (PSA) value represent a great diagnostic problem. Magnetic resonance imaging (MRI)-guided biopsy demonstrates high prostate cancer detection rates in these patients if functional MRI is suspicious for prostate cancer. However, MRI-guided biopsy is no...
