To analyze the diffusion and perfusion parameters of central gland (CG) prostate cancer, stromal hyperplasia (SH), glandular (GH) to determine role these in differentiation CG cancer from benign hyperplasia.In this institutional review board-approved (with waiver informed consent), HIPAA-compliant study, 38 foci carcinoma, SH nodules, GH nodules were analyzed 49 patients (26 with carcinoma) who underwent preoperative endorectal magnetic resonance (MR) imaging radical prostatectomy. All...
The objective of our study was to investigate whether quantitative parameters derived from diffusion-weighted imaging (DWI) and dynamic contrast-enhanced MRI (DCE-MRI) correlate with Gleason score angiogenesis prostate cancer.Seventy-three patients who underwent preoperative radical prostatectomy were included in study. A radiologist pathologist located the dominant tumor on MR images based histopathologic correlation. For each tumor, apparent diffusion coefficient (ADC) value DCE-MRI (i.e.,...
Abstract Purpose To determine relative diagnostic value of MR diffusion and perfusion parameters in detection active small bowel inflammation patients with Crohn's disease (CD). Materials Methods We reviewed 18 CD terminal ileum (TI) who underwent enterography (MRE; including dynamic contrast enhanced MRI diffusion‐weighted MRI). Conventional findings TI were recorded. Regions interest drawn over normal to calculate apparent coefficient (ADC), the volume transfer constant (K trans ) media...
The aim of this study was to investigate and compare the therapeutic effect three different combinations in conservative treatment carpal tunnel syndrome (CTS) by means clinical electrophysiological studies. included tendon- nerve-gliding exercises combination with splinting, ultrasound splinting ultrasound, exercises. A total 28 female patients (56 wrists) electrophysiologic evidence bilateral CTS were studied. In all patient groups, significantly effective immediately 8 weeks after...
Presents a novel estimator for the time-dependent spectrum of nonstationary signal. By modeling signal, at any given frequency, as having time-varying amplitude accurately represented by an orthonormal basis expansion, authors are able to compute minimum mean-squared error estimate this amplitude. Repeating process over all frequencies, they obtain power distribution function time and frequency that is consistent with Wold-Cramer evolutionary spectrum. Based on model assumptions, develop...
Magnetic resonance (MR) imaging has been established as the best modality for detection, localization, and staging of uterine cancers. Recently, usefulness diffusion-weighted (DWI) in diagnosis cancers reported several studies.To calculate apparent diffusion coefficient (ADC) values normal zones well benign malignant diseases, to determine a cut-off ADC value quantitative detection malignancies with DWI.Eighty-seven patients (mean age 53 years) 107 pathologies 50 healthy controls 38 were...
Magnetic resonance (MR) imaging has been increasingly used in the evaluation of prostate cancer. As studies have suggested that majority cancers arise from peripheral zone (PZ), MR focused on PZ gland thus far. However, a considerable number (up to 30%) originate transition (TZ), substantially contributing morbidity and mortality. Therefore, research is needed TZ gland. Recently, advanced techniques gaining acceptance TZ. In this article, features cancers, role cancer detection staging,...
Crohn's disease (CD) is a chronic autoimmune disorder that affects mainly young people.The clinical management based on the Disease Activity Index and especially biologic parameters with or without additional endoscopic imaging procedures, such as barium computed tomography examinations.Recently, magnetic resonance (MR) has been promising diagnostic radiologic technique lack of ionizing radiation, enabling superior tissue contrast resolution due to new pulse-sequence developments.Therefore,...
We present a novel data-adaptive estimator for the evolutionary spectrum of nonstationary signals. model signal at frequency interest as sinusoid with time-varying amplitude, which is accurately represented by an orthonormal basis expansion. then compute minimum mean-squared error estimate this amplitude and use it to that frequency, all while minimizing interference from components other frequencies. Repeating process over frequencies, we obtain power distribution consistent Wold-Cramer...

We used the results from first three screening rounds of Bahcesehir Mammography Screening Project (BMSP), a 10-year (2009-2019) and organized population-based program implemented in county Istanbul, Turkey, to assess potential cost-effectiveness mammography Turkey.Two strategies were compared: BMSP (includes biennial screens for women between 40-69) Turkish National Breast Cancer Registry Program (TNBCRP) which includes no screening. Costs estimated using direct data project reimbursement...
The purpose of this study was to prospectively investigate the effect sonographically guided corticosteroid injection on clinical and radiologic responses in patients with proximal plantar fasciosis.Thirty-one consecutive unilateral fasciosis were enrolled. A 4-cm 21-gauge needle positioned a caudocranial oblique manner, withdrawn near edge fascia so that solution dispersed around edge. Two milliliters (20 mg/mL) lignocaine/prilocaine, 1%, 0.5 mL mg) methylprednisolone acetate solutions...
Background: The Bahcesehir Breast Cancer Screening Project is the first organized population based breast cancer mammographic screening project in Turkey. objective of this prospective observational study was to demonstrate feasibility a program developing country and determine appropriate age (40 or 50 years old) start with Turkish women. Materials Methods: Between January 2009 December 2010, total 3,758 women aged 40-69 were recruited study. conducted biannually, five rounds planned. After...
