- Investigate the science behind how doctors use radioactive drugs and PET scans to detect and diagnose diseases like Alzheimer’s and cancer.
--
Is there a way to detect diseases like cancer and Alzheimer’s before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can detect the spread of diseases before they can be spotted with other types of imaging. So how exactly does this work, and is it safe? Pedro Brugarolas investigates.

*All the respect to people that work in Hospitals!*
YES!
BabunKing why did you say ,,yes,, yerdk so bad taste yrderrrrrr kho
Again you, go find some work dude.
(also the researchers and engineers that develop the technology)
But I dont respect the healthcare cost, ill cost you an arm an a leg or all your libs
Wait.... Hospitals have particle accelerators?
What's cooler is they are colliding electrons (matter) and positrons (anti-matter) and recording their energy trace. People are already finding application for antimatter in our lifetime!
I do amused
Soudamini Panda what
LOLOL that's what I said
Adithya Prakash Yeah, that's what I said
I wonder why these cyclotron was in hospital.. No body had patience to answer to my question... Now i got answer ted-ed.. Your way of explanation with crystal clear animation is very good.. Thanks for your video Ted-ed.. You people are educating us...😀
@LagiNaLangAko23 was that dark humor and a pun? Wow 😭
You're saying that of he waits, he'll get cancer soon enough...as 60% of people do.
And that if he's *PATIENT* enough....as in a hospital PATIENT waiting for their pet scan, you'll find out🤷♂️ or am i just looking in it too deep
Modern medicine never ceases to amaze me! Science is the true miracle.
Jesus believes in science!
Jesus you don't even need that.....
Thanks Jesus very cool
Hello, Jesus!
Nowadays, we have combined physics, chemistry, and medicine to save lives. We've gone so far. That's why I don't understand why there are flat earthers and anti vaxxers.
It may be a combination of unhealthy paranoia combined with lack of understanding.
@@razzvyberry4694 I agree with you. That's why we need to educate our people more.
@@FishoeShoe_da_great indeed, education is very much the solution, unfortunately, a lot of people refuse to look at thinks logically or accept that their point of view is wrong. It may be a bigger problem that we do take the time to try and teach people, but we hit a brick wall. I wish the word to be better, and being open minded is a quality that I feel is lacking on a general scale.
Don't live in past boys. Flat Earthers had long been dead. Now everyone knows science and let's engage in some serious stuff.
@@PrinceKashyap. I wish it where that way. While flat earthers are hard to find and they barely even exist, not everyone knows science per say. Nevertheless, finding reasonable people is possible and it's much more fun to speak to someone who has the ability to admit they may be wrong and are willing to listen and learn.
Because they need to heal them in a flash.
is this a reference to the tv show?
Get out
What a 'dad' joke
Hahaha!
You've out there buying cigarette for 12 years dad. Please come back.
Are you sure that's how Positron Emission Tomography works?
Yep. I'm positive.
Ok google
Can I delete someone's youtube account
Other Viewers: woah that's amazing... What is your opinion?
Me: yes
why do so many people on yt have your icon?
Of course something as cool as a particle accelerator would also have a badass name ending in -tron. You don't wanna mess with the Cyclotron.
It's got a younger brother called Synchrotron, which is even more badass! It is essentially what the LHC is, and enabled us to discover the Higgs boson!
sounds like something from transformers
Great animation! One addition. Why do Cancers take up radio contrast dye? because tumors have a rich blood supply and they consume more glucose/energy than normal cells as they divide fast.
But what if a normal cell consumes them up? A false positive?
@@PrinceKashyap. All cells can consume these glucose-based radiotracers but cancer cells do it in higher ammounts. You then look at the distribution of it in the body. If a region/spot is strangely "bright" in PET when it shouldn't be, that probably is wrong and you then you start thinking what it could be.
@@matheusribeiro8523 A'ight I got it. Btw, just checked out your channel, that's some amazing skill you got there.
Nice presentation.
O Allah keep me and the one who read this comment away from those virulent diseases, and help those who have it💔
Back to back videos.
Another reason not to do my homework.😁
I use this video as research for a school job
I've been doing a lot of research into particle physics and radiation (7th grade physics is boring) and I finally found a way to apply what I've learned. Watching a TED-Ed video always makes me feel great.
As a medical imaging technician, thank you for this highly informative video 😊👌💥
hello fellow medical imaging technician 👋🏼
@@aguuuung08 Hello colleague! 🙌
Hi Seniors!👋
All the respect to you and to the working team on these amazing videos..
All thanks to scientists and researchers who save our lives ❤️
We don't even know the name of scientists whose inventions made our day to day life luxurious, but we all know about useless historic political figures. General awareness should be based on basic sciences not based on who was whose father.
@@GAMEOVER-yy6zj I 100% agree ! Well said.
My questions have been answered by watching these videos, and I learn new information. Thank you Ted Ed!😀
I never heard of particle accelerators in hospitals until earlier today, so this was just on time!!
I love how ingenious this technology is. The sheer amount of time and effort required to create such a system must have been monumental. Well done, everyone involved.
How in the world did someone come up with this or even the CT scan machine??.... How!???😕😵
CRAZY RESPECT TO THEM!!🖖
CODM Aiden what’s crazy is the things that are possible that haven’t been invented yet.
Yes...It takes a lot of ingenuity to incorporate such high-energy phenomena into medical applications. Props to all the scientists that made such a revolutionary detection mechanism possible!
Personally, I think the animation is one of the best parts and pairs very well with what they teach in the videos.
In 1988 I was 12 years old and started volunteering at my local hospital. No one would explain these questions. Thank you so much. I have waited over 30 years for this very video
This animation is top notch! Truly amazing!
I have no idea about any of this but I Love The Relaxing Voice
*Plot Twist:* The accelerator is actually a Hulk serum.
Ohhhh... So that's how Ben Ten's watch works
Pew News.
@@azrafrahman8456 no seriously no
84÷6=14.
174×62=10788.
@@azrafrahman8456 ohh ohkayy
Last few videos were not as good. But this one is completely awesome. I was just waiting for a science video. Well done TED-Ed.👍
Excellent video, thanks TED-Ed!!
I was at the NYC concert too! It was iconic
Thank you Ted ed for keeping me uptdated on the latest technologies
This was very *illuminating!*
Wow, never thought hospital house a partial accerlator! Thanks for this, this is truly awesome.
I always wandered why, thanks for answering Ted Ed!
And in process of gaining wisdom from humans we develop more humane nature and methods. They in turn make us empathetic and compassionate. That’s why we have particle accelerators at hospitals; because of the wondrous curiosity that lies within the brains of wondrous beings called humans and their desire to do good for their fellow beings. Thank you Ted ♥️
Hey there
Awesome and informative video
What an interesting video covering a question I never knew I wanted to know.
Love this channel.
Ted ed I love this channel...
Awesome animation Ted ed
Wow...Proud of Science!
The Power of Science and Technology in Constructive Way... 🎆🎊🎉👍
0:21 that is so satisfying to watch
except the person who has cancer, of course.
Exactly! Mujahid Syed
I love how that doctor is smiling at that persons brain tumour like "Yeah this is fine."
Great animation. Adoooooooooro
The medical advance is simply amazing.
This is insanely cool.
Love those quotes at the beginning
Bob Stickman they really get you thinking and wondering, i enjoy them too.
Lovely educational video!! Can you make one on Parkinson's disease?
Today my physics teacher taught us about cyclotron and recommend us to see this video!
It's very interesting 👍
This is very Smart Chanel
wow thanks a lot
Luv ur vids!!!!!!!!!
Graciaaas!! me ayudaste con mi tarea
Oh finally I understand something about cyclotron.
This channel is beyond our education system.
It was help full ,love from India 🇮🇳
WOW! This is crazy!
Hi There! Have A Fun Time Scrolling😊😊
I've seen 3 tracer comments already, no i don't
But I am already tracer.
marvellous
This is the Juncture where Physics, Chemistry and Biology meet.
You explained PET even better than my Radiology teacher in college 😊
me too! i need to find lots of sources to fully understand how PET/SPECT works. worse thing is, i live in non-english speaking country and most of those sources are in english :| so glad this video exists
@@aguuuung08 yeah, entire radiation medicine is difficult, we medicos are not well versed most of the time with physics in detail and the principle of radiation medicine needs us to be good at that.
Try improving english because most of the sources are in English, in my country we have this coaching institute "DAMS" try their online app, their radiology teachers are good...
Thank you for uploading this video!
Btw, doesn’t oxygen-18 have 8 protons and 10 neutrons?
I'd never even thought of what other machines was needed for PET scans to work, I always just thought the necessary things were the computer and the chemicals within the room.
I had a newclear stress test in Dec 1 2020. It was a good time to get a new one who is a good idea to have a chance of getting into an option to make sure it is not a big deal of a dangerous at all times.
Hello Ted-ed, I am a native Arabic speaker, and am looking forward to enhance my language support onto any of your videos; unfortunately and for some reason these aren't enabled for community contribution ,any reply about that? thanks in advance.
My mom was having a PETscan while I was watching this. She has traveled melanoma under her right armpit and they're trying to find the original tumour. Thankfully, survival rates for traveled melanoma are above 90%
Because they watch Rick and Morty
Stop
Please make Arabic captions on videos ....there are very good and useful 🌸
Can't resist on clicking a new Ted ed notification
Like if you also cannot resist
Um, to "accelerate particles" amirite?
AYYY Cyclotrons. UBC student here! We got the biggest one! Gotta represent!
Great explanation and animations are awesome ..keep it up.. 😇
Could you do a video of hyperhidrosis?
In fact, hospitals have another type of particle accelerators... a linear accelerators (LINAC), in an Radiation Oncology area.
With a LINAC, they could obtain electrons and photons... and then treat cancer. 😊😊😊
Fun fact that you can also use FDG to find osteomyelitis in the body because the body uses a lot of resources to fight the infection and heal the bone I needed that injected into me over the summer because I had acute osteomyelitis
A TED ad had also came with this video
Fascinating to see the utility of cyclotron.Just appeared for physics boards 2019 which was very tough as quoted by everyone hahahhahahahahaha.Cyclotron derivation was there.
Particle accelerator? Dr. Wells we would like to know your location! Barry? Cisco? Caitlin ya there?
Should Have Built A Time Machine.....
Meh ,
My local hospitals don't have these equipments yet.
Yes I am from a underdeveloped location.
Hospital are pretty mysterious....
Nice vídeo. Just one caveat, it is a serious misconception that no amount of ionizing radiation is completely safe, and it is not based on scientific evidence.
It is also relevant to know that aside of F-18, produced with accelerators, the most widely used radioisotope for this kind of diagnostics (with tens of millions of procedures per year) is Technetium-99m, which is produced in nuclear reactors.
It's nice to see someone memtion 99mTc.PET imaging is better but is only a fraction of what nuclear medicine can do and, on it's own, faces numerous issues with widespread use.
This is my job :3. Well said Ted-Ed
How can you cure a phobia or to be specific claustrophobia? Due to this I’m always afraid to go to hospitals. I always get a dark feeling going to elevators and always thinking about how Ironic a hospital can be hell to people with phobias.
Whenever this narrator says "the clock is ticking", I get a micro panic attack.
In my hospital us radiographers do the injecting and imaging.
Had stress test in nuclear images on my heart scans, and she accidentally took a picture of my vertebrae were I dislocated vertebrae in L1 L2 and then they saw a fractures behind the 2 vertebrae that had a fracture by mistake was a good thing.
My previous job at producing FDG and maintaining Cyclotrons ^^
Hello !
Sending admirations to our beloved Radiologic Technologist, who specializes in nuclear medicine (nuclear medicine technologist) 💉💉💊💊. ☺️☺️☺️ .. underrated but visceral.. 💓💓💓💓💓
You missed that cancer centers use linear accelerators to treat cancer.
Wow
Cool
Roses are red
Violets are blue
Im not first
Neither are you
mangesh kolvankar
you are not the first but do you really care ?
What's that's mean🤷
2019 Medical student 🙏
Wow...humans and their huge brains.
Yeah except the people here complaining about radiation and how positrons and electrons "aren't even real"
The particle accelerator in STAR labs seems more cooler
My concern is wd all Flu-18 leave the body system eventually, though low, still is remains.
So if I understood correctly, we can determine if there's a tumor when a certain area has accumulated FDG? Wouldn't it be possible to see it when blood has accumulated on that area? (Since the tumor has blocked the blood flow)
The scan doesn't detect blood, and i don't think cancer doesn't stop the blood flow really, just sucks up the nutriens and other stuff that it's carrying(feel free to correct me)
Watch the video how the scan detects the radiation off the accumulated stuff inside the cancer please :)
Matter-antimatter anihlation emits a gamma ray, not "something like an x-ray." Right?
Ive undergone a pet scan like this. I got scared shitless when i saw the radiation symbol on the huge metal syringe before i got injected lmao. I had to lay still for a while afterwards. I could swear i felt the radiation soar trough my body(obviously just some placebo going on lmao).
it's not a placebo effect...
What do you do for a living? "I diagnose cancer and other diseases with radioactive decay into antimatter" Radiologists definitely have the coolest job description
