BACKGROUND Chest radiography after central venous catheter (CVC) insertion is the main method of verifying the catheter location. Despite the widespread use of radiography for detecting catheter position, x-ray may not always be readily available, especially in the operating room. OBJECTIVES We aimed to compare contrast-enhanced ultrasonography (CEUS) and chest radiography for detecting the c...

The incidence of osteoporotic fractures increases with age. Osteoporosis could, consequently, become a significant social/healthcare problem in developed countries where the population is aging. An early diagnosis of osteoporosis is fundamental to preventing complications and unnecessary suffering. This is now possible using precise imaging methods. The two main aims of imaging are to identify ...

This in vivo study evaluated the dissociation quality of maxillary premolar roots combining variations of vertical and horizontal angulations by using X-ray holders (Rinn -XCP), and made a comparison between two types of intraoral radiography systems - conventional film (Kodak Insight, Rochester, USA) and digital radiography (Kodak RVG 6100, Kodak, Rochester, USA). The study sample was comprise...

Shear coaxial injectors are a common injector type for liquid-rocket-propulsion applications and can be found in many oxygen/hydrogen engines. These injectors rely on the shear between an outer lower-density, high-velocity annulus and a higher-density, low-velocity inner jet to atomize and mix the propellants. Because of the dense-jet core, the optical densities of these sprays are high, partic...

Electron Beam welding is becoming more important in Indian industries due to the growing automation of the process and superior weld quality, resulting from virtually zero heat affected zone (HAZ). Two main types of defects are often encountered in EB welding joints viz void type defects and crack type. EB welding joints must be radiographically inspected for all these types of defects and it i...

Introduction: The clinical techniques utilized in the assessment of the health status of articular cartilage of synovial joints include x-ray radiography, magnetic resonance imaging and ultrasound (1). Conventional radiography provides the highest spatial resolution (2) and is the most commonly used technique. However, because cartilage is not visible with standard x-rays, the radiographic eval...

BACKGROUND The aim of this study was to evaluate the usefulness of noise reduction procedure (NRP), a function in the new image processing for chest radiography. METHODS A CXDI-50G Portable Digital Radiography System (Canon) was used for X-ray detection. Image noise was analyzed with a noise power spectrum (NPS) and a burger phantom was used for evaluation of density resolution. The usefulnes...

The purpose of this pictorial review is to illustrate chest imaging findings of cystic fibrosis (CF) using tomosynthesis (digital tomography), in comparison to radiography and computed tomography (CT). CF is a chronic systemic disease where imaging has long been used for monitoring chest status. CT exposes the patient to a substantially higher radiation dose than radiography, rendering it unsui...

OBJECTIVE To assess whether accident and emergency (A&E) nurses using the Ottawa Ankle Rules could detect all ankle fractures. DESIGN Prospective observational study. SETTING A&E department of a university teaching hospital. SUBJECTS All patients who presented with ankle injuries who were initially assessed by a nurse taught the Ottawa Ankle Rules. OUTCOME MEASURES (1) The numbers of pa...
