BACKGROUND Radiography, typically the first-line imaging study for diagnosis of craniosynostosis, exposes infants to ionizing radiation. We aimed to compare the accuracy of cranial ultrasound (CUS) with radiography for the diagnosis or exclusion of craniosynostosis. METHODS Children aged 0 to 12 months who were assessed for craniosynostosis during 2011-2013 by using 4-view skull radiography a...

BACKGROUND Public health authorities worldwide discourage the use of chest radiography as a screening modality, as the diagnostic performance of chest radiography does not justify its application for screening and may even be harmful, since people with false positive results may experience anxiety and concern. Despite the accumulated evidence, various reports suggest that primary care physician...

In the spring of 2002, a mail survey was conducted to determine the use of individualized radiographic examinations (selective radiography) for comprehensive care patients at all sixty-four U.S. and Canadian dental schools. Results from previous surveys were used to evaluate the long-term longitudinal trends. Among sixty-two schools (97 percent response rate), selective radiography was used by ...

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 ...

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...

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...
