OBJECTIVE To investigate radiation doses in pediatric chest radiography in a national survey and to analyze the factors that affect radiation doses. MATERIALS AND METHODS The study was based on the results of 149 chest radiography machines in 135 hospitals nationwide. For each machine, a chest radiograph was obtained by using a phantom representing a 5-year-old child (ATOM® dosimetry phantom,...

Introduction Digital dental radiography was introduced in 1987, and many thought this technology would quickly take over as the standard in dental radiology. However, this has not been the case as only 7% to 8% of dental professionals currently use digital imaging systems (1). Many dentists have been resistant to change as the diagnostic quality of digital radiography has been questionable when...

Introduction: The aim of this study was to determine the accuracy of digital panoramic radiography in estimating the crestal width of implant fixtures after surgery. Materials and Methods:We selected 241 digital panoramic images after implant insertion which had documented information of their actual size. The crestal width was measured on radiographs. We compared two measuring methods in diff...

Introduction The aspiration to ensure early diagnosis for all people with tuberculosis (TB) [1], combined with recent advancements in digital technology, has brought chest radiography back to the forefront for TB detection. Once a mainstay for TB control in the community, but discouraged once bacteriology became the standard for TB diagnosis, chest radiography has recently come back into favour...

Carestream has implemented companion views in its digital radiography systems. A companion view is designed to complement the standard processed radiographic image delivered from the digital radiography capture modality to PACS, to provide an additional rendering tailored for the visual interpretation needed for a specific diagnostic or clinical purpose. Two companion views are available in Car...

To the Editor: I am writing in response to a recent article published in the June issue of Imaging Science in Dentistry by Demirturk Kocasarac and Celenk titled “Effectiveness of digital subtraction radiography in detecting artificially created osteophytes and erosions in the temporomandibular joint.” The authors compared the diagnostic efficacy of panoramic radiography and panoramic digital su...

Background and Aim: Secondary caries are a common challenge for dentists. Many researchers have evaluated the accuracy of digital radiographic systems in the detection of secondary caries and have reported controversial results. Therefore, the aim of this in vivo study was to determine the diagnostic accuracy of digital radiography in the detection of secondary caries in anterior teeth. Mate...

introduction: vertical root fracture (vrf) is a common failure in endodontically treated teeth. due to vrf’s poor prognosis, a reliable and valid detection method is critical for treatment planning. conventional and digital radiographs are limited in vrf detection. recently, cone beam ct (cbct) system has been introduced. this study aimed to compare the diagnostic accuracy of these three imagin...

Secondary caries is the most common cause of dental restoration failures. This study aimed to compare the diagnostic accuracy of conventional and digital intraoral radiography and cone beam computed tomography (CBCT) for detection of recurrent caries around composite restorations. mesio-occluso-distal (MOD) cavities were prepared using bur on 45 extracted sound human molar teeth. The teeth were...

Dear Editor, The selection of appropriate diagnostic techniques is an important step in the treatment of disease. An optimal diagnostic method can provide essential information, while minimizing cost and harm to patients. In dental radiography , attempts have been made to reduce patient exposure to radiation. Cone-beam computed tomography (CBCT) and digital radiography were developed to achieve...
