Conventional radiography plays an essential diagnostic role in the primary evaluation of acute joint trauma. In complex fractures, however, computed tomography (CT) is an imaging modality often used second to radiography. As a result of technical breakthroughs in the field, multidetector CT (MDCT) allows faster imaging and better temporal, spatial, and contrast resolution compared with conventi...

OBJECTIVE Successful endodontic therapy depends on adequate mechanical and chemical debridement of the canal which requires knowledge of the canal morphology. Conventional radiography has been used to evaluate the canal type; however, direct digital radiography has recently been practiced for this purpose due to the shortcomings of conventional radiography. The aim of the present study was to c...

introduction: ultrasonography is currently being used as one of the diagnostic modalities in various medical emergencies for screening of trauma patients. the diagnostic value of this modality in detection of traumatic chest injuries has been evaluated by several studies but its diagnostic accuracy in diagnosis of pulmonary contusion is a matter of discussion. therefore, the present study aimed...

introduction: traumatic chest injuries (tci) are one of the most common causes of referring to the emergency departments, with high mortality and disability. this study was designed to evaluate the diagnostic accuracy of ultrasonography versus chest x ray (cxr) in detection of hemo-pneumothorax for patients suffering penetrating tci. methods: the present cross-sectional study was performed to e...

Background: A study has been conducted to assess two useful radiation protection indices, the annual per-capita effective dose equivalent (AED) and the genetically significant dose (GSD), from conventional diagnostic radiography in 10 counties with more than 1,886,000 inhabitants in Khorasan province in Iran. Materials and Methods: The health centre authorities of Khorasan province were asked t...

Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...

INTRODUCTION Endodontic diagnosis depends on accurate radiographic examination. Assessment of the location and extent of apical periodontitis (AP) can influence treatment planning and subsequent treatment outcomes. Therefore, this systematic review and meta-analysis assessed the diagnostic accuracy of conventional radiography and cone-beam computed tomographic (CBCT) imaging on the discriminati...

Diagnostic radiography is a leading cause of man-made radiation exposure to the population. Individual risk assessment and analytic epidemiologic studies likewise require retrospective assessment of lifelong exposure from medical sources. Typical schemes attempt to determine accumulated doses of specific „critical organs“. The organ dose to the red bone marrow is relevant in studies of diseases...

Osteoarthritis (OA) is a common degenerative musculoskeletal disease highly prevalent in aging societies worldwide. Traditionally, knee OA is diagnosed using conventional radiography. However, structural changes of articular cartilage or menisci cannot be directly evaluated using this method. On the other hand, ultrasound is a promising tool able to provide direct information on soft tissue deg...
