The best use of CEA is as a tumor marker, especially for cancers of the gastrointestinal tract. When the CEA level is abnormally high before surgery or other treatment, it is expected to fall to normal following successful surgery to remove all of the cancer.he most frequent cancer which causes an increased CEA is cancer of the colon and rectum. Others include cancers of the pancreas, stomach, breast, lung, and medullary carcinoma of the thyroid and ovarian cancer.
Screen refresh rate is the number of times an image on any type of monitor or television is reconstructed per second. This is measured in hertz.. (Hz) For example, a TV witâ¦h a refresh rate 60Hz, reconstructs the image you're seeing 60 times every second. Basically, the higher the refresh rate on a tv, the representation of motion will be smoother, and the image will flicker less.
The refresh rate is the number of frames per second the television can display. Its unit is a Hertz, which is equal to 1/second. 120Hz means it can draw 120 images per second.The refresh rate of televisions is a bit misleading and is mixed with a few marketing gimmicks.The increased refresh rate (120Hz and higher) was introduced by manufacturers as an indirect way to find a solution to the motion blur problem of LCDs and LEDs. television supporting 24p playback does not have this issue. For a LCD/LED display, this means a refresh rate of either 120Hz or 240Hz. 24 frames fits exactly in 120 frames per second. 120/24=5, so each frame is displayed 5 times.
