In Brief Study Design. This study's design was a cross-cultural validation of the Neck Disability Index and Pain Scale. Objectives. objective to translate, culturally adapt, validate Brazilian Portuguese version (NDI-BR) Scale (NPDS-BR). Summary Background Data. Although several valid measures exist for measurement neck pain functional impairment, these have yet been validated in Portuguese. Successful linguistic cultural translation may allow appropriate comparison clinical laboratory...
The purpose of our study was to identify the spectrum MRI appearances untreated liver metastases from different primary origins.Over a period 52 months, we used clinical information system retrospectively first MRIs obtained in 165 consecutive patients who had metastases. All histologic confirmation tumor. Liver were confirmed at examination, on imaging, or follow-up. MR sequences included T1-weighted spoiled gradient-echo, T2-weighted half-Fourier acquisition single-shot turbo spin-echo,...
Purpose: To retrospectively determine the sensitivity and specificity of magnetic resonance (MR) imaging for differentiation between acute chronic cholecystitis, with histopathologic analysis as reference standard. Materials Methods: Institutional review board approval waived informed consent was obtained this HIPAA-compliant study. Four reviewers blinded to cholecystitis type but aware that present evaluated MR images predetermined findings in 32 patients (15 male, 17 female; mean age ±...
The objective of our study was to describe 10-year experience using MRI evaluate response local thermoablative interventions in the treatment malignant liver lesions.This retrospective conducted from 1998 2008. studies were performed at 1.5 and 3 T acquired < 4, 4-9, > 9 months after radiofrequency ablation (RFA), cryoablation, microwave ablation. MR features evaluated on basis signal intensity unenhanced T1-weighted images presence ill-defined perilesional enhancement, well-defined lesional...
To investigate the effect of a radioprotective oral agent containing formulation antioxidants and glutathione-elevating compounds on extent x-ray-induced γ-H2AX foci formation.The study was approved by local ethics committee informed consent obtained from each subject. In vitro experiments with blood lymphocytes 25 healthy volunteers were performed without added either before or immediately after irradiation (10 mGy). For in vivo/in tests, samples before, 15, 30, 60 minutes (n=17) after, 2,...
The purpose of this report is to describe the magnetic resonance (MR) imaging features hepatic inflammatory myofibroblastic tumor (IMT). Two observers retrospectively analyzed images from six MR examinations in four consecutive patients. Tumor location, size, extent, morphology, and number; signal intensity on nonenhanced images; enhancement pattern serial gadolinium-enhanced duct wall thickness; presence biliary dilatation, vascular invasion, lymphadenopathy were assessed. findings compared...
To evaluate the ability of MRI to identify intra- and extraintestinal findings celiac disease in an adult population.Forty-one subjects (18 men 23 women; mean age = 41.3 years; 31 with biopsy-proven disease, 10 healthy volunteers) underwent small bowel. MR studies were performed on a 1.5-T magnet using T2-weighted half-Fourier single-shot turbo spin-echo (HASTE) true fast imaging steady-state precession (True-FISP) sequences. The features sensitivity, specificity accuracy some these are...

Background. Few functional outcomes scales have used Item Response Theory (IRT) for validation. IRT allows individual line item validations and offers substantial advantages over classic methods of scale validation or the simplest from known as Rasch. Rasch analysis reduces data to dichotomous variables thus decreasing sensitivity Likert-type responses.
