OBJECTIVES To compare the prevalence, clinical and radiographic characteristics of psoriatic spondyloarthritis (PsSpA) in psoriatic arthritis (PsA), with ankylosing spondylitis (AS). METHODS A prospective single-centre cross-sectional observational study recruited consecutive PsA and AS cases. Participants completed outcome measures, and underwent clinical examination, axial radiographic scor...

-The factors influencing imaging quality of industrial digital radiographic imaging system are analyzed detailedly. This imaging system is a new type industrial digital radiographic imaging system developed by author, The structure of ray conversion screen and its non-uniformity, the discordance analysis of scientific grade CCD and vignetting effect of the optical system are introduced. The cor...

CONTEXT Constipation is a distressing condition for advanced cancer patients and is frequently underdiagnosed. OBJECTIVES The primary objective of this study was to determine if a strong correlation existed between the use of the Constipation Assessment Scale (CAS) and a plain abdominal radiograph in the interpretation of constipation in patients with advanced cancer. The secondary aim of the...

INTRODUCTION AND PURPOSE Conventional x-ray films and radiochromic films have inherent challenges for high precision radiotherapy dosimetry. Here we have investigated basic characteristics of optically stimulated luminescence (OSL) of irradiated films containing carbon-doped aluminum oxide (Al2O3:C) for dosimetry in therapeutic photon and electron beams. MATERIALS AND METHODS The OSL films co...

PURPOSE To assess agreement between digital and film photography for research classification of diabetic retinopathy severity. METHODS Digital and film photographs from a 152-eye cohort with a full spectrum of Early Treatment Diabetic Retinopathy Study (ETDRS) severity levels were assessed for repeatability of grading within each image medium and for agreement on ETDRS discrete severity level...

this study was an attempt to identify the interlingual strategies employed to translate english subtitles into persian and to determine their frequency, as well. contrary to many countries, subtitling is a new field in iran. the study, a corpus-based, comparative, descriptive, non-judgmental analysis of an english-persian parallel corpus, comprised english audio scripts of five movies of differ...

background: conventional tomography used for evaluation of the small areas of the jaws provides acceptable information. it has some advantages of availability, less radiation dose and costin comparison to computed tomography (ct) and cone beam ct. double emulsion film usuallyused for taking tomograms requires less exposure than single emulsion film; on the other hand,the latter provides more sh...

OBJECTIVE to determine whether 3D reconstruction images from computed tomography (CT) increase the inter and intraobserver agreement of the Neer and Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification systems. METHODS radiographic images and tomographic images with 3D reconstruction were obtained in three shoulder positions and were analyzed on two occasions by four independent ob...
