| non-ionic contrast media | <radiology> A class of radiographic contrast media which do not ionise in solution, thereby decreasing effective osmolarity and toxicity. (05 Mar 2000) |

| successive contrast | The visual effect caused by viewing a brightly coloured object and then a gray surface; the latter appears tinged with the complementary colour of the object. Viewing a surface coloured in the complementary colour of the object rather than in gray enhances the colour intensity of the surface. (05 Mar 2000) |
| differential interference contrast | <technique> A mode of contrast generation in microscopy that yields an image with a shadow relief. The relief reflects the gradient of optical path difference. Differential Interference Contrast, which is a form of interferenc microscopy that uses polarizing beam splitters, can be of the Smith or Nomarski type. Acronym: DIC (05 Aug 1998) |
| double contrast enema | After evacuation of a barium enema and injection of air into the rectum, radiographs show fine details of mucosa of the rectum and colon. (05 Mar 2000) |
| iodinated contrast | A substance that contains iodine that can be injected, swallowed or given as an enema for the purpose of diagnostics. Iodinated contrast is radiopaque. This means that conventional X-rays will highlight the course of the contrast in the body. (27 Sep 1997) |
