Hello, I know a little of topic and without boring you all with why im asking i would like to ask peoples views on these types of scans.
Thanks
I've had over 40 in the last 5 years, and I wouldn't be here without them so I guess they're good. Or at very least better than the
alternative that Lymphoma offers
I know folk have reservations about radiation and x rays but for me I didn't have a choice.
Feel free to U2U if you want to know any more.
I've also had PET scans too btw

Noisy but nice! Never had one but watched hundreds!
+1
I (and my wife) would rather have the/A CT scan. Without them my wife would possibly not be here now as the (28.4mm) lump would probably NOT have
shown up on an X-ray.
Edit bit
Oh and the medico boys on the front line in you know where, are, after doing it them selves, trying to get medical practise changed in the UK so that
anyone who presents at a hospital with possible trauma or other medical conditions gets a CAT scan first, as this has speeded up ALL susequent
diagnosis of complaints. Its more expensive but cheaper and more cost effective in the long term than messing around with Xrays.

Also goes for my younger brother!
Both my wife and I had one at New Year after an RTA. Very quick - possibly a little disconcerting if you don't like enclosed spaces but ours
were over pretty quickly. The results were available very quickly. Having seen the results later the images are extremely clear and capable of
magnification to a high degree. The images are in electronic format (as opposed to X-rays etc) so are easily transferable - my wife's images
were sent from Kent to a London hospital for a specialist to view before her neck brace etc could be taken off - was very quick in the circs.

i work for a company that makes radiotherapy machines (linear Particle Accelerators). all our new machines have built in ct scanners, we use them to
verify that the patient is in the correct position before we radiate the tumor. the kind of radiation we use for ct is fractionally worse than what
you would be exposed to at the dentist when they do an xray of your head.
just to put it into perspective to take a ct image you need about 100-120 thousand volts. To create the kind of radiation that can kill/damage cells
you need about 6 millionvolts
this is one of our machines up at the National Physics Laboratory near hampton court. this machine is capable of producing from 6 to 25million volts
of radiation energy out of the top part where as the ct scanner tube (far right at 3pm) will max out at around 130kilovolts
lucky cancer patients will get a ct scan every day they have treatment to verify they are in the correct position before treatment, meaning most have
a ct every day for 2-4weeks. even still all of those scans added together isnt even a fraction of one radiation treatment they receive to kill of
their cancer.
so if you want an opinion of someone that works with radiation every day.............. dont even worry about it the dose is very very minimal and the
benefit of the resulting images outstrips the risk by a million fold.
My toys. 7tonne comes in kit form believe it or not
the table in the picture is an engineering version not a normal patient table. its accurate to 0.001mm that took a bit of doing, built all in the
aim of holding a device that can measure gray in absolute. one measurement can take several weeks to complete.
Wow , that's going to cost a bit more than £250
@ashg awesome pics. Love seeing the things that you'd never normally see!
I've have a few, though nowhere near 40, for similar if less serious reasons to Liam.
Not as noisy or claustrophobic as an MRI machine (just like being pushed through the hole of a really big donut.
The contrast squash you get given tastes horrible (orange is the least worst).
If you need to have the high contrast injection (don't look at the automatic syringe as it's huge) it feels like you've p*ss*d yourself
for a few seconds, but it otherwise nothing to be worried about.
Saved my life so I'm not complaining.
Hope everything turns out ok.
2 million euros if you want one with all the toys on, then there is the cost of the bunker with over 1m thick concrete walls. if you go for a high
power 25mv version you need to cover the walls in 15mm thick boron impregnated nylon to stop free neutrons getting through. those little beggers are
nasty as they are the same little bleeders that are used to start nuclear chain reactions in power plants.
if you like i can try and stick a few more pictures up. i have to be a bit careful what i put on the net as i work in r&d and our competitors
would love to see what we are up to behind closed doors
Thank you for your replys
I understand that they are life savers in certain situation. But for doctors to use them as a risk assessment tool? with the higter radiation dose
involved.
Take the cardiac ct scan will have a radiation dose of 10msv or higher and they have to scan the patient before that to find where things are, yes at
a lower dose but it all adds up.
Natural background radiation is about 2.4msv a year higher in some places, so a cadiac cta will give you about five years worth in 3-4minutes.
What do you think? please tell me if you think i wrong.
ashg, great pictures, do you get tested for radiation?
thanks

I recently went to hospital for chest pains, and the doctor told me that a CT scan was the last option in terms of diagnosis. Apparently the stats suggest that about 1 in 1000 people develop cancer as a result of a CT scan so the risk isn't huge, but neither is it negligible.

Ashg, that was very well said and i here what your saying
Boy what a job you have
