Very good introduction to the topic, thanks!

Thanks for this description of CT. A high level view is great to provide. One clarification is that in the video you mention that each image i taken in CT is a different layer of the body. Each image taken is a different view of the body and the different layers are computed. Thanks again.

videos like this one or the one on mammography you did, would be so helpful on educating patients... if you only had them in different languages for local markets. Or even subtitles would do

I have very severe Asthma and will be doing this soon. I got told it's a chest CT Scan. I'm just curious to what it's capable of finding and what it can't do or find?
Let's just say someone has the world's deadliest disease, cancer, chickenpox, tumor or anything. Can it detect those?
To me, it can't because its about the chest area vs elsewhere?

Can it see things in the tissues? Eksempel parasits? Or bigger like tapeworms?

Ionized radiation from a CT scan is dangerous, isn’t it?
Isn’t low dose a misnomer? Because no amount of radiation expose is good for the body.
One x-ray is one thing, but there must be hundreds of x-ays taking during one of these CT scans.
The contrast medium substance contains iodine, correct?
