بررسی ارزش Diffusion Weighted Imaging در تصاویر MRI برای تشخیص سرطان پروستات
Background: Prostate cancer is the third leading cause of death and is the most common cause of cancer in elderly men. Regarding to the low accuracy of screening methods such as prostate-specific antigen (PSA), Digital Rectal Examination (DRE) and trans rectal ultrasound (TRUS) in detection and localization of tumor, Magnetic Resonance Imaging (MRI) and Diffusion Weighted Imaging (DWI) attracte...
متن کاملCombined T2-weighted and diffusion-weighted MRI for localization of prostate cancer.
OBJECTIVE The objective of our study was to compare T2-weighted MRI alone and T2 combined with diffusion-weighted imaging (DWI) for the localization of prostate cancer. SUBJECTS AND METHODS T2-weighted imaging and DWI (b value = 600 s/mm2) were performed in 49 patients before radical prostatectomy using an endorectal coil at 1.5 T in this prospective trial. The peripheral zone of the prostate...
متن کاملValue of T1/T2-weighted magnetic resonance imaging registration to reduce the postbiopsy hemorrhage effect for prostate cancer localization
BACKGROUND The aim of this study was to evaluate the value of T1/T2-weighted imaging (T1/T2WI) registration to reduce the postbiopsy hemorrhage effect for prostate cancer localization on prostate magnetic resonance imaging (MRI). METHODS Twenty-one men with pathology-proven prostate cancer who underwent preoperative MRI in a single institution were selected. The zonal anatomy was divided into...
متن کاملProstate cancer detection in patients with total serum prostate-specific antigen levels of 4-10 ng/mL: diagnostic efficacy of diffusion-weighted imaging, dynamic contrast-enhanced MRI, and T2-weighted imaging.
OBJECTIVE The purpose of this study is to evaluate the utility of T2-weighted imaging, dynamic contrast-enhanced MRI (DCE-MRI), and diffusion-weighted imaging (DWI) for detecting prostate cancer in patients with total serum prostate-specific antigen (PSA) levels of 4-10 ng/mL, which is referred to as the "gray zone." MATERIALS AND METHODS Fifty patients with gray-zone PSA levels underwent MRI...
متن کاملSignal Intensity of High B-value Diffusion-weighted Imaging for the Detection of Prostate Cancer
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...
متن کاملEvaluation of the Potential of Dwi in Prostate Cancer Detection
Background: Conventional T2W imaging alone has a poor sensitivity for prostate cancer detection. This study therefore evaluated combined T2-W and diffusion weighted (DW)-MRI vs. T2-W MRI alone for identifying tumour in patients with prostate cancer. Material and Methods: 54 consecutive patients with prostate cancer (46 Stage 1 and 2, 8 stage 3) and sextant biopsies within the previous 3 months ...
