background and aims. while the use of x-ray is increasing, professional responsibility of dentists entitles them to have sufficient and correct knowledge of using radiographs. the aim of this study was to assess the level of knowledge of correct prescription of radiographs among dentists in yazd, iran. materials and methods. this was a descriptive cross-sectional study including 134 general den...

We present a case of a 53-year-old woman with subchondral insufficiency fracture (SIF) of the femoral head without history of severe osteoporosis or overexertion. Plain radiographs showed acetabular overcoverage with excessive lateralization of the acetabular rim. A diagnosis of SIF was made by typical MRI findings of SIF. The lesion occurred at the antipodes of the extended rim. Increased mech...

Rheumatoid arthritis (RA) leads to a progressive weakening of the skeleton which may result in bone fractures. However, spontaneous fractures (exclusive of stress fractures, vertebral collapse, and superficial articular fragmentation) in patients with rheumatoid arthritis have been only occasionally reported in the medical literature. A case of spontaneous talar and calcaneal fracture in rheuma...

The paper describes the contribution made to the understanding of the epidemiology of osteoarthritis by the Arthritis Research Campaign Epidemiology Unit. Kellgren and Lawrence defined the condition radiographically and produced the widely used Atlas of Standard Radiographs of Arthritis. They documented the age- and sex-specific prevalence of osteoarthritis. Based on studies in occupational gro...

chest radiography is a common diagnostic imaging test, which contains an enormous amount of information about a patient. however,its interpretation is highly challenging. the accuracy of the diagnostic process is greatly influenced by image processing algorithms;hence enhancement of the images is indispensable in order to improve visibility of the details. this paper aims at improving radiograp...

Objective: This first aim of this study was to determine whether there is a relationship between the presence Haller cells and Schneiderian membrane thickness (SMT) by considering factors such as age gender. The second investigate correlation visibility on cone beam computed tomography (CBCT) digital panoramic radiographs. Materials Methods: Seventy-eight edentulous patients were included in st...

The aim of this study was to evaluate the reject rate periapical and bitewing radiographs among dental undergraduate students Universiti Kebangsaan Malaysia (UKM), identify type radiographic errors which are frequently encountered compare rates between Year 3, 4 5 undergraduates. 118 rejected 27 were collected from UKM undergraduates’ polyclinics for a duration 10 months. These further evaluate...

the use of mammography film-screen is limited in general radiography. the purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). fourteen other radiographs were ...

Demonstration of small apical pneumothoraces is supposed to be facilitated by expiratory chest radiographs. This study aimed to analyse the assumed enhancement of visual contrast on expiratory chest radiographs in patients with small apical pneumothoraces. Optical densities (OD) were obtained with a densitometer (X-rite 3001) on 54 paired inspiratory and expiratory chest radiographs of 22 conse...
