• Scatter radiation.

What is radiographic contrast?

Contrast is the difference in density or difference in the degree of grayness between areas of the radiographic image.

What are different types of contrast?

What kinds of contrast are available? There are three broad kinds of contrast available: IV, PO, and PR (rectal). IV contrast is either gadolinium for MRI or iodinated contrast for CT. PO contrast for all ER and inpatient CT scans is dilute iodinated contrast (same agent used for IV contrast in CT).

How many types of contrast are there?

The two main types of iodine-based contrast media are ionic and nonionic. The development of ionic contrast media in the 1920s and 1930s allowed radiologists to visualize vessels and organs on various imaging studies.
