BACKGROUND Conventional radiography is insufficient for diagnosis in a small but not unimportant number of hip fractures, and secondary imaging with computed tomography (CT) or magnetic resonance imaging (MRI) is warranted. There are no convincing observer variation studies performed for conventional radiography or CT in occult fractures, and no large materials for MRI. PURPOSE To assess obse...

OBJECTIVE In this study we compared cardiothoracic ratio on chest radiography and left ventricular dimensions from echocardiography in patients with left heart valvular regurgitation. METHODS The studied population consisted of 107 patients (55 male, 52 female) aged 7 to 25 years (11.6+/-4.7 years) with isolated mitral or aortic regurgitation. Chest radiography and echocardiographic examinati...

BACKGROUND Management of acute respiratory tract infection varies substantially despite this being a condition frequently encountered in pediatric emergency departments. Previous studies have suggested that the use of antibiotics was higher when chest radiography was performed. However none of these analyses had considered the inherent indication bias of observational studies. OBJECTIVE The a...

introduction: the aim of this study was to compare the diagnostic value of cone-beam computed tomography (cbct) and periapical (pa) radiography in detecting internal root resorption. methods and materials: eighty single rooted human teeth with visible pulps in pa radiography were split mesiodistally along the coronal plane. internal resorption like lesions were created in three areas (cervical,...

o bjectives: early diagnosis of incipient and non cavitated carious lesions is crucial for performing preventive treatments. the aim of this study was to compare the effi- ciency of three diagnostic methods of bite-wing radiography, diagnodent, and visu- al examination in diagnosing the incipient occlusal caries of permanent first molars. materials and methods:  in this diagnostic cross-section...

Background: Radiography as a concept has mainly been associated with the functional role of the radiographer. The concept has been studied from a theoretical point of view. However, there is a lack of a theoretical foundation and research on the actual substance of the term radiography used in education. It is therefore important to undertake an investigation in order to determine how students ...

It is difficult to take intraoral radiographs in some patients who are intolerable to place the film in their mouth. For these patients, Newman and Friedman recommended a new technique of extraoral film placement. Here we report various cases that diagnostic imaging was performed in patients using the extraoral periapical technique. This technique was used to obtain the radiographs for the pati...
