BACKGROUND Upper respiratory tract problems, eg, acute sinusitis are frequently occurring illnesses in returned travelers. The most accurate and cost-effective method for diagnosing these upper respiratory tract illnesses in hospital-based settings remains an area of uncertainty. In the present retrospective cohort study, the usefulness of routine sinus radiography in the diagnostic work-up of ...

This article on digital radiography image processing and display is the second of two articles written as part of an intersociety effort to establish image quality standards for digital and computed radiography. The topic of the other paper is digital radiography image acquisition. The articles were developed collaboratively by the ACR, the American Association of Physicists in Medicine, and th...

In 52 patients we compared the accuracy of standard anteroposterior (AP) radiography, mortise radiography and MRI with arthroscopy of the ankle for the diagnosis of a tear of the tibiofibular syndesmosis. In comparison with arthroscopy, the sensitivity, specificity and accuracy were 44.1%, 100% and 63.5% for standard AP radiography and 58.3%, 100% and 71.2% for mortise radiography. For MRI they...

Neutron radiography systems based on Gd, Dy and In metallic foils and X-ray films have been used at this centre since early seventies for various NDT and R&D work in nuclear, defense and aerospace industries. In recent years use of digital detection systems such as neutron scintillator and CCD based imaging systems and photostimulated luminescence based phosphor imaging plate systems have been ...

Welded constructions play a vital role in power plant components. Power industry utilization of radiography for integrity of welds is a common practice in the vessel manufacturing industry. Recent developments in the field of ultrasonic utilize Time of Flight Diffraction Technique (ToFD) for evaluation of welds with respect to Engineering Critical Assessment approach for evaluation of welds. Re...

conclusions despite close concordance between ultrasonography and chest radiography, ceus is not a suitable alternative for standard chest radiography in detecting cvc location; however, considering its high sensitivity and acceptable specificity in our study, its usefulness as a triage method for detecting cvc location on a real-time basis in the operating room cannot be ignored. results chest...

BACKGROUND With soaring advances in the field of medicine, the place of older radiologic imaging modalities is being reduced to basic screening tools. Yet the modern imaging modalities like computerized tomography (CT), magnetic resonance imaging (MRI), ultrasound and nuclear medicine are hardly available. STUDY OBJECTIVES To study the frequency of various indications of plain chest radiograp...

Digital radiography has become the norm in U.S. hospitals. The ability to view images, postprocess, and transmit the images systemwide immediately are distinct advantages. Yet, these technical advances create challenges for the radiology community, including the need to re-educate the workforce and prevent unnecessary radiation exposure. This education process is even more important for those w...

Fundamental and clinical evaluation of chest CT imaging in detectability of pulmonary nodules was carried out in comparison with projection chest radiography including conventional screen-film system, advanced multiple beam equalization radiography (AMBER System), and computed radiography with imaging plate (CR). Detectability of simulated nodules in the fundamental study and of metastatic pulm...

PURPOSE Rib fractures are the most common skeletal thoracic injuries resulting from blunt chest trauma. Half of the rib fractures are not detected upon a precise physical evaluation and radiographs. Recently ultrasonography (USG) has been investigated to detect rib fractures. But based on literature the usefulness of USG varies widely. This study was conducted to investigate the role of USG in ...
