Aims Chest radiography is the first choice for the investigation of cardiovascular and respiratory disease. Radiographer technologists are responsible for managing the radiation exposure to patients and providing adequate image quality according to the ALARA concept. The knowledge and experience of radiographers in performing chest radiography helps to improve the diagnosis of diseases. The aim...

Background & Aims: Conventional radiography is used for the diagnosis of problems such as dental caries and failure in root canal therapy. The diagnosis accuracy of conventional radiography is acceptable in the evaluation of anatomical and pathological structures. However, it seems that by using digital radiography we can obtain more information in this field. The aim of this study is to compar...

background and aims. in periapical radiographic technique, the changes will be visible only after considerable deposition or resorption while digital subtraction technique visualizes slight density changes. this study was aimed to compare visualization of density changes in conventional periapical radiographs and digital subtraction technique with or without image enhancement. materials and met...

introduction: although proximal dental caries are very common, clinical examinations cannot detect them all. panoramic radiography has been widely used in dentistry for both diagnosis and screening. this study aimed to investigate and compare the efficacy of two digital panoramic radiography techniques in the diagnosis of proximal caries. methods: a total number of 60 patients referred to a den...

background and aims. the aim of the present study was to compare the effect of application of an image processing mode of a colorizer on the efficacy of the detection of interproximal carious lesions viewed in direct digital radiography. materials and methods. a total of 102 proximal surfaces of extracted human premolars on direct digital images were evaluated by three observers with and withou...

introdouction: canal length measurement is essential for proper endodontic treatment. any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. digital radiography has enabled accurate measurement of curved canal length. in this study, we evaluated the accuracy of calibration of a complementary met...

introdouction: the purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (pmi), mandibular cortical width (mcw), and antegonial notch depth (ad), in digital panoramic radiographs. materials and methods: pmi, mcw, and ad were calculated in digital panoramic radiographs of ...

objective: after introduction of digital radiography into dentistry several methods of image acquisition were accessible in the field of dentistry. in many instances it is necessary to digitize analog images. there is no overall acceptable method for image digitization so all different types of images can be comparable. the objective of this study was to compare the diagnostic accuracy of diffe...

OBJECTIVES To compare the differences between conventional radiography and digital computerized radiography (CR) in patients presenting to the emergency department. METHODS The study enrolled consecutive patients presenting to the emergency department who needed chest radiography. Quality score of the radiogram was assessed with visual analogue score (VAS-100 mm), measured in terms of millime...
