The study aimed to compare the sensitivity and specificity of digital radiographic systems for the diagnosis of proximal carious lesions. Extracted human teeth (3 canines, 3 premolars, and 3 molars) were submitted to one of three types of proximal lesions (demineralized area, cavity affecting the enamel alone, and cavity affecting enamel and dentin). Bitewing radiographs were obtained from each...

The introduction of digital imaging and diagnostics facilities has fundamentally changed radiology. Nevertheless, theory of digital image processing and analysis as well as their practical application are still only a subsidiary part in nowadays radiology technician curricula. This work focuses on the evaluation, to what extent the authors’ simplified and standardized process model for applying...

The use of digital imaging for the diagnostic purpose has been increased during last few years. This technique has brought advancement in the field of radiography. The effect of digital imaging on workflow has a direct relation with the performance of technologists. Aim: The predestined aim of this study was to analyze the use and influence of digital imaging on the workflow of the radiologists...

UNLABELLED This paper reports the design and implementation of an innovative and cost-effective imaging management infrastructure suitable for radiology centres in emerging countries. It was implemented in the main referring hospital of Bhutan equipped with a CT, an MRI, digital radiology, and a suite of several ultrasound units. They lacked the necessary informatics infrastructure for image ar...

Computed radiography (CR) systems are becoming prevalent in diagnostic radiology as the availability of lower cost devices and the increased emphasis on digital image networks in radiology occurs. Basic knowledge of the CR system and an understanding of system characteristics by the radiologist, physicist, and technologist are important for the installation and operation of these devices in the...

This paper on digital mammography image acquisition is 1 of 3 papers written as part of an intersociety effort to establish image quality standards for digital mammography. The information included in this paper is intended to support the development of an ACR guideline on image quality for digital mammography. The topics of the other 2 papers are digital mammography image display and digital m...

Three-dimensional (3D) computer modeling, simulation, and rendering techniques were used to redesign the diagnostic workstations and radiology reading rooms for a proposed hospital with particular attention given to lighting conditions, noise reduction, and optimal use of limited workspace. The results were presented to a panel of multidisciplinary experts and iteratively improved and redesigne...

The clinical efficacy and physicians' assessment of a medical image management system (MIMS) for chest images that involved the medical intensive care unit (MICU) and the radiology department were evaluated. A token-passing fiber-optic network was implemented to connect display stations in the MICU and in the chest reading area in the radiology department with a laser film digitizer and an arch...

STUDY OBJECTIVE To compare digital to conventional film-screen pulmonary angiography for the diagnosis of acute pulmonary embolism (PE) in a clinical population. DESIGN Retrospective review of patient data, ventilation/perfusion (V/Q) lung scintigraphy reports, and pulmonary angiographic reports. SETTING University hospital, division of interventional radiology. PATIENTS AND METHODS Patie...

Future radiology practices assume that the radiology reports should be uniform, comprehensive, and easily managed. This means that reports must be “readable” to humans and machines alike. In order to improve reporting practices in breast imaging, we allow the radiologist to write structured reports with a special pen on paper with an invisible dot pattern. In this way, we provide a knowledge ac...
