modern medical imaging technology is absolutely amazing
And lethal
@@randomyoutuber8249 if you or someone you know has suffered an injury or died at the hands of a CT scanner, you may be entitled to money damages. Please contact our law firm.
@@Shlooomth I will definitely be doing that
@@Shlooomth how do I contact this law firm?
Thanks for the explanation
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.
the video is amazing is underrated
a very useful video to share with the starter of radiography.
It's great to know
Thank you so much, it is soo helpful ❤
Thanks your video I understand what I Don,t understand teachers of university so thanks your video
非常實用的科普知識. Useful knowledge.
Amazing
Perfect just perfect explanation!
Thanks
Nice animation
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
You can use subtitles
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?
The video comes in hand coz I connect it via skyworth with added cameras
Colon or large intestine ulcers can be seen in ct scan?
Please understand that we cannot answer individual questions about indications here. We recommend that you ask your doctor for details about diagnostic imaging with computed tomography.
Can it see things in the tissues? Eksempel parasits? Or bigger like tapeworms?
With CT such parasites can rarely be seen directly within the pictures but often signs of such an infection like liver cysts in case of Echinococcosis.
Thank you Simens

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?
yes it’s dangerous but it’s used to help diagnose fairly fast.
You’re on the right track. Yes it’s dangerous to get a bunch of CT scans a year, that’s why we check prior exams to make sure the patient is not getting more than what they need. There are safety protocols that need to be followed.
As for all radiation is bad, the diagnostic importance of man made radiation outweighs the risk of radiation-related pathologies, like a Chloe said. So most times it’s necessary.
There is also a theory called radiation hormesis that argues that low dose radiation can help stimulate the body’s ability to repair itself. However that’s all it is, a theory.
In addition, did you know you absorb radiation on a daily basis from the sun and from radioactive substances found in the very walls of your home? You also absorb a lot of radiation when you’re on an airplane (you are technically closer to the sun, therefore the UV rays are more intense).
There’s no escape 😂
@@Outsayeed Risk versus reward. Perhaps the information obtained is worth the risk of DNA destruction during a scan. But, CT scans beam x-rays through the body. That is radiation expose and not really safe.
@@Outsayeed CT SCAN IS EXTREMELY DANGEROUS!!
worse than getting radiation naturally (all at once rather than over years)?
Radiation from x-ray photon energy is not cumulative, the damage is.
Natural Background Radiation is average if 1.5 - 3 mGy per year. Divide that by 365 days then the by 24 hours.
That is radiation dose that does not penetrate your body.
1 CT scan of the chest and Deposits directly inside your body over 1000 mGy in 15 seconds.
I leave the calculations and decision making to you.
Now how do we know the dose?
Average radiation dose is measured and calculated by the CT scanner based on having a pencil type Geiger counter in a centre of a phantom.
based on that measurement the CT Scanner calculates the dose length product which is the total dose went inside the patient, for example from top of the brain to the end of the cerebellum.
that dose is recorded automatically in the patient file. And in some places with no conflict of interest like ours the total dose is displayed on the digital image or printed on the film.
I call it deposited because that’s the real dose that reached the centre of the body part exposed.
Google average DLP in Australia from the ARPANSA website.
And next time you get a CT scan ask the Radiographer or Technologist, what was the DLP you received. It is your right to know.
I have seen on the CT scanner, some patients receiving over 1.5 Gy in a single CT scan of the brain.
there are many beneficiaries who will try anything to lure patients and hide the truth from people and lure them to have a scan. It’s all about the money and not you. You are just dollars in their bank.
And there many ignorant people who learnt nothing from their studies and they become teachers with PhD, teaching the new generation deceptive gobbledygook science. They didn’t even bother reading the dose displayed on the CT scanner.
you want to know the risks? Read Prof John Matthews research conducted at the Melbourne university and published in the British Medical Journal (2013). There are few other studies at that magnitude done in other countries publishing similar outcomes.
the risk of developing cancer from a single CT scan examination is 24% higher than the unexposed general population, and then additional 16% for every additional CT scan.
@@Outsayeed the only true fix for radiation is the discovery of Cancer kill drug, that you take once and you never again get cancer
please reply my question i am 22 yrs and i get only 1 ct scan of appendix and ct scan reports are normal but i am very stressed and worried about that ct scan cause cancer in future please tell me how do i detox my body and keep safe from ct scan side effects
Thank you for reaching out. It's important to consult a doctor for information and guidance regarding your specific condition. They can provide personalized advice and address your concerns.
Dude....As soon as you get it, you got the radiation. There is no going back. If you needed it, then I hope it was worth while. I just denied a PA at a hospital giving me a contrast one over a tooth infection because it didn't make any sense to me.
I would rather have an MRI.
This can help find pancreatic cancer I think everyone should get this
I like how little you know about this haha
👋
😋
kat scan ⁉️
Blessings in an abundance of the faith. I salute you. 😘🙏Grace and peace be unto you and to this place. God bless you. 🤍Thank you. Will you believe and receive Jesus Christ as your LORD and personal saviour??? I do. 😊
Tooo many test too many scan technology not good
Nice animation
