STUDY DESIGN A variety of interbody implants were imaged by computed tomography and plain radiography within cadaveric spines to evaluate their basic imaging characteristics. OBJECTIVES Sources of interpretation error by both computed tomography and plain radiography of interbody implants were investigated. SUMMARY OF BACKGROUND DATA Lucencies have been reported around bone dowel implants i...

This article on digital radiography image acquisition is the first 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 processing and display. The articles were developed collaboratively by the ACR, the American Association of Physicists in Medicine, and the...

introduction: the purpose of this in vitro study was to compare the accuracy of working length determination using the apex locator versus conventional radiography in c-shaped canals. methods and materials: after confirming the actual c-shaped anatomy using cone-beam computed tomography (cbct), 22 extracted c-shaped mandibular second molars were selected and decoronated at the cemento-enamel ju...

Increasingly, veterinarians are using medical imaging to diagnose their patients. There is a corresponding tendency towards replacing conventional film-screen systems with digital medical imaging systems, such as computed radiography (CR) and direct radiography (DR). With these systems, many veterinarians around the world are enjoying considerable benefits, including time savings and optimal im...

Several studies have demonstrated that a diagnosis based solely on a patient's medical history, physical examination, and laboratory tests is not reliable enough, despite the fact that these aspects are essential parts of the workup of a patient presenting with acute abdominal pain. Traditionally, imaging workup starts with abdominal radiography. However, numerous studies have demonstrated low ...
