We use very low-dose, high-speed CT scan imaging compared to conventional CT scanners. This lets us get the best image with the lowest possible radiation exposure. It also means your child needs to stay still for a shorter amount of time during the scan.
In a published study, we showed how we reduced the number of full-dose CT scans by 42% in a 1-year period. The low-dose scans used one-half or less radiation than a standard CT scan of the head. Even with less radiation, images were of a high enough quality to make the diagnosis.
With our high-speed scanner, CT exams that once took many minutes now take less than 10 seconds. This makes it less likely that your child will move during imaging so there is less need to:
- Give your child medicine to prevent them from moving
- Repeat imaging because of movement during the scan
The high-speed CT scanner also lets doctors capture activity in the body that lasts a very short time. One example is CT scanning that requires injecting a dye to highlight blood vessels as the dye passes through them. The dye remains in one place for only a few seconds before it flows away. Conventional CT technology is too slow to make a picture of the blood vessels before the dye disappears. By capturing 16 cross-sectional images (slices) per half-second, the high-speed scanner gets the job done.
