Alongside the paint range, you can buy a couple of “technical” paints, two of which I haven’t used yet, the third, the Contrast Medium, I’ve used loads of. So much that when painting the Warcry scenery, I’ve had to buy a second bottle. There are a couple of reasons for this. Timing Phase of Contrast Media for CT. The timing of image acquisition, relative to the time of injection of the contrast agent, can impact which anatomic structures harbour the greatest concentration of the administered contrast. This phenomenon is most important for CT. Five phases of contrast enhancement for CT imaging are discussed below. Iodinated and gadolinium-based contrast media are used on a daily basis in most radiology practices.
