radiograph

 [ra´de-o-graf″]
an image or record produced on exposed or processed film by radiography.
Relative positions of x-ray tube, patient, and film necessary to make the radiograph shown. Bones tend to stop diagnostic x-rays, but soft tissue does not. This results in the light and dark regions that form the image. From Thompson et al., 1994.
bite-wing radiograph a type of dental radiograph that reveals the crowns, necks, and coronal thirds of the roots of both the upper and lower posterior teeth, as well as the dental arches, produced using bite-wing film.
cephalometric radiograph a radiograph of the head, including the mandible, in full lateral view; used to make measurements; called also cephalogram.
flat plate radiograph a radiograph that visualizes abdominal organs and some abnormalities. It is usually one of the first diagnostic studies performed in assessing a patient for gastrointestinal disorders; no special physical preparation of the patient is necessary.
panoramic radiograph a type of extraoral body-section radiograph on which the entire maxilla or mandible can be depicted on a single film.

The authors said their results showed that most children with negative chest radiograph would recover fully without needing antibiotics, and argued there was a place for chest radiography in the diagnostic process, to rule out bacterial pneumonia.
The ability of dental assistants to take quality radiographs is a great asset to the dental practice, saving time and cost and creating a less stressful work environment.
The study was carried out in the Medeniyet University Goztepe Training and Research Hospital Emergency Medicine Department using 100 chest radiographs collected from the Radiology Department's archive after obtaining approval from the Medeniyet University Goztepe Training and Research Hospita Ethics Committee (10.02.2015 /2015/0007).
Retrospective analysis of trauma patients at an urban Level I Pediatric Trauma Center revealed that there was no information gained with the additional diagnostic test of pelvic radiograph against CT interpretation, and plain digital pelvic radiographs had less than desirable sensitivity in picking up fractures/subluxations (see Figure 1).
A child is exposed to an estimated radiation dose of 0.05-0.005 mSv per single limb radiograph [13].
Consequently, the contribution of this revisited method is the ability to handle the drop-outs and unreliable parts of the prosthesis captured in radiographs. As the contour detection and a feature matching are not required by the intensity-based registration, the computation is much more simple in comparison with the previously published approaches.
(Correct dichotomized Strongly response) agree and % correct (1) Did the student match (140) 92.1% the correct original radiograph? (2) If a single rooted tooth (True) 74.3% (21) 13.8% had an endodontic procedure, is it possible to match ante and post-mortem radiographs.
Caption: Figure 1: (a) Pre-operative radiograph reveals incomplete obturation in 46 and 47 and an extra root in 46, (b) radiograph showing working length determination using electronic apex locator Root Zx, (c) radiograph showing master cone suitability of gutta-percha to canals, (d) post-operative radiograph showing endodontic restoration in 46 and 47 with amalgam
Several biologic indicators have been used to assess individual skeletal maturity, such as chronologic age, dental evaluations, secondary sexual characteristics, height increase, hand-wrist radiographs, and maturity of cervical vertebrae (6).
Results: In general, significantly more residual root-filling material was detected in the photographs of the split roots (gold standard) than in the radiographs. Comparing orthogonal and eccentric projections, only slight differences in cleanliness were found.
Radiographs with a high degree of clarity aid endodontists in determining the quality of root canal therapy and the presence or absence of periapical lesions [7].
