Radiography is a familiar and available imaging modality for the evaluation of patients with acute abdominal distress. Potential causes for acute abdominal distress include the hepatobiliary system, spleen, urogenital tract, and gastrointestinal tract. Radiographic signs associated with specific conditions are described, including gastric-dilation volvulus, urinary bladder rupture, ureteral rup...

Abstract Aims: Detection of marginal gaps at the implant-impression coping interface before impression-making is a common clinical task in prosthodontic treatment. Dental radiography is the most commonly used method for intraoral detection of gaps. The objective of this study was to assess the effect of implant connection design on the detection of experimentally-created marginal gaps at the im...

OBJECTIVE To compare nurse practitioners with senior house officers (SHOs) for their ability to request and interpret correctly a limited range of x ray views of patients attending a minor injuries unit. DESIGN Retrospective analysis of case records. METHODS 150 accident and emergency (A&E) records with x ray requests were randomly selected from the SHOs' first, second, and third 2-month pe...

Radiographic images can provide quantitative as well as quantitative information if they are subjected to densitometric analysis. Digital radiography consists of four major steps which include X-ray detection, digitization, image processing and display. The digitization process varies from device to device and may suffer variations even when the same digital equipment is used throughout time. A...

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

UNLABELLED Radiographic arthrography and bone scintigraphy are common diagnostic procedures used for evaluating total hip prostheses. In this study, both techniques are combined, and nuclear contrast imaging (nuclear arthrography) is added. The efficacy of the procedures is evaluated. METHODS After intravenous injection of 99mTc-methylene diphosphonate (MDP), standard radiographic arthrograph...

Pulmonary function abnormalities after exercise are suggestive of pulmonary edema; however, radiographic evidence is lacking. Well-trained cyclists were studied to determine whether there is radiographic evidence of pulmonary edema after endurance exercise (cycling distance 5.3-131.5 km) at altitude. Chest radiographs obtained before exercise were coded for later interpretation. Films obtained ...

Several agents show an effect on reducing radiographic progression in rheumatoid arthritis. It is tempting to retrospectively compare the effects of these agents on radiographic progression across clinical trials. However, there are several limitations in interpreting and comparing radiographic results across clinical trials. These limitations, including study designs, patient characteristics, ...
