Radiogram

Following my usual custom, with some difficulty I removed the radiogram from the mount and found in the upper one half of the left border a radiopaque shadow in the area previously covered by the film mount frame. […] This indicated that another radiogram should be made, which revealed an impacted third molar in disto-oblique position.

The method I use is to outline the contour of the chest wall on an X-ray film and to transpose it on a sheet of paper. If the radiogram has been taken correctly, the outline of the chest will be clearly visible on the film, the edge of the ribs contrasting quite sharply against the shadow of less density given by soft parts covering the thorax.

[F]ractures in animals, which were on a diet that deranged their calcium and phosphorus metabolism healed normally as judged from histological sections. But when radiograms were taken of these fractures they revealed little callus and hence the radiograms would normally be interpreted as indicating non-union; that is, that a bony callus had not formed. […] Accordingly, radiograms do not always give an accurate indication of whether or not osteogenesis has occurred.
