Abstract The structure of five rare filigree spheres from a seventeenth century shipwreck was examined in order to unravel their condition, manufacturing process and function. This study focuses on the application non-invasive imaging techniques: optical microscopy, X-radiography, X-ray micro-computed tomography neutron computed tomography. A valuation different aspects applied techniques made,...

Background: Panoramic radiography creates distortion in teeth position and inclination especially lateral areas of the arches due to acquisition curved shape dental arch. The aim this study was evaluate panoramic compared cone-beam computed tomography. Methods: Mesiodistal angulations were measured on radiography. buccolingual inclinations determined tomography scans. previous measurements then...

We performed direct radiographic magnification (X3) using a 0.1-mm microfocal tube and computed radiography (CR) in air-barium double-contrast studies of the stomach and duodenum. To eliminate blurring of the image due to motion, we used the maximum kilovolt peak rate possible (102 kVp), the maximum milliampere second rate possible (64 mAs), the shortest possible exposure time (0.1 second), and...

introduction: rapid diagnosis of traumatic intrathoracic injuries leads to improvement in patient management. this study was designed to evaluate the diagnostic value of chest radiography (cxr) in comparison to chest computed tomography (ct) scan in diagnosis of traumatic intrathoracic injuries. methods: participants of this prospective diagnostic accuracy study included multiple trauma patient...

one of the main causes of endodontic treatment failure is the clinician’s inability to localize all the root canals. due to the complex anatomy of the root canal system, missed canals are not uncommon. there are several strategies to decrease the possibility of missed root canals starting with good pre-operative radiographies. in order to overcome the limitations of conventional radiographies, ...

A 51-year-old Japanese man presenting with acute abdomen was admitted to our hospital. Contrast-enhanced computed tomography (CT) led to a diagnosis of gastroenteritis on admission (Picture 1A). Contrast-induced oliguric acute kidney injury followed by septic shock developed, and the serum creatinine level rose from 0.98 mg/dL to 5.07 mg/dL, requiring temporary hemodialysis. Kidney-shaped enhan...

including the Navy’s Fleet Readiness Centers (FRC) are faced with replacing aging chemical and film-based radiographic imaging systems used for non-destructive testing (NDT) (or nondestructive inspection (NDI)) with systems that do not rely on such an approach—so called computed radiography (CR) systems. However there are benefits, requirements, concerns, and challenges associated with implemen...

Chronic dyspnea of pulmonary origin raises concern for chronic obstructive pulmonary disease or interstitial lung disease. A chest radiograph is recommended as the initial imaging study. When chest radiography is nonrevealing or provides no definitive diagnosis, a high-resolution chest computed tomography is indicated. The high-resolution chest computed tomography should include expiratory imag...
