Closely related to radiographic contrast is the concept of exposure latitude.
2.
Negative radiographic contrast agents are air and carbon dioxide ( CO 2 ).
3.
KVp controls the resulting photographic property called " radiographic contrast " of an x-ray image ( the amount of difference between the black / whites ).
4.
In order to image the body so that the maximum information will result, higher subject contrast areas require a higher kVp so as to result in a low radiographic contrast image and vice versa.
5.
Murphy's motor-driven, high-pressure angiographic injectors are used for injecting a small amount of radiographic contrast ( a solution containing iodine, which is easily visualized with x-ray images ) into select vessels in the body.
6.
It should be remembered that the test strip only measures cation concentration, it is therefore possible that urine with a high concentration of non-ionic solutes ( such as glucose or urea ) or with high molecular weight compounds ( such as the media used to provide radiographic contrast ) will yield a result that will be erroneously lower than that measured by densitometry.
