background and aims. radiography is used to diagnose the demineralization process and carious lesions; however, conventional radiography and direct digital images do not show these lesions when the amount of demineralization is less than 40%. digital subtraction radiography has recently been used to improve the diagnostic quality of these lesions. the purpose of this study was to compare the ca...

Belma Muhamedagic, Lejla Muhamedagic Faculty of Medicine, University of Sarajevo, Bosnia and Herzegovina ography-RVG, Trophy Radiologie, Croissy Beaubourg, France [now Trophy, A Kodak Company, Rochester, N.Y.]). RVG is modern diagnostic method based on use of digital roentgen. Principle is use of so called CCD chip in RVG sensor (Figure 1) that put in patient’s mouth (3). The first dental digit...

IntroductionThe radiography profession is challenged by greater responsibilities and shortage of educated radiographers. Implementation task shifting one strategy to deal with the current situation in health care. The aim this studiy was evaluate radiographers’ perception assistant nurses carrying out tasks that traditionally were undertaken within a Swedish context.MethodsAn electronic questio...

Background: One of uncommon complications in patients with peritoneal catheter is colon rupture which usually occurs during catheter insertion. In this paper, we present a case of delayed perforated colon following insertion of peritoneal catheter. Case presentation: A 37-year-old man was suffering from chronic renal failure (CRF). Nine months after peritoneal catheterization, peritoneal dialy...

Purpose: Root fracture is a clinical problem which often is difficult to detect and diagnose. As the root fracture detection is based on demonstration of a fracture line or lines, radiographic examination is important. The aim of this study was to compare diagnostic efficacy of direct digital radiography with conventional radiography for detecting experimental root fractures. Materials & Method...

Differential phase contrast imaging using grating interferometer is a promising alternative to conventional X-ray radiographic methods. It provides the absorption, differential phase and scattering information of the underlying sample simultaneously. Phase retrieval from the differential phase signal is an essential problem for quantitative analysis in medical imaging. In this paper, we formali...

THE use of contrast media in the orbit dates from 1927, when Staunig and Herrenschwand injected air into the episcleral space, and since that time various media have been used. The ideal medium should provide good contrast in small quantities, be non-irritant, and have suitable qualities of permeation and absorption. The following media will be considered: (1) Air or other gas, (2) Oily media, ...

The purpose of this investigation is to quantify and evaluate the diagnostic image quality dental panoramic radiography with without post-processing visualization. 72 photos were analyzed split into two groups: post processing image. Each picture was given a score based on subject's perception anatomical zone features, as well density contrast According these specifications, digital system that...

mediastinal lymphangioma is primarily a benign lesion and the majority of the cases are found incidentally. these lesions account for approximately 1% of all mediastinal tumors. here we present a giant mediastinal cystic mass in a 35-year-old female who was presented with severe respiratory distress. on the plain chest radiography and ct scan, a massive left pleural effusion with large paraster...

abstract background: the radiographic image accuracy depends on the x-ray film information visibility. good visibility is found by good contrast. radiation exposure parameters (kvp, mas) and film processing conditions have impact on contrast. in dentistry radiography machines, exposure time and processing procedure are set by radiographer. no optimized exposure time and processing conditions ma...
