Hi there my dad has a MRI scan Friday and a CT scan Wednesday,whats the difference,he has a Malignant Rectal Tumor?
Have a look at this link which will take you to the cancer research area which lists all scans:
Cheers Tony.Do you think they are a bit quick getting all these appointments though.He has MRI on Friday and CT on Wednesday,Just wondered if they are classing it as urgent xxx
To be honest they generally class all 'suspected' cancers as urgent....That is good timings for the scans as some on here have waited several weeks, but you should be happy that they are taking it seriously...It is better whether it is or isn't cancer you will get the news in a relatively quick time.
Hello there styphmyster, to answer your question,
I have had both, and they vary slightly, I do know the exact technical differences, it's a bit scientific for me, so I'll tell what the experience is like instead.
The CT scan was a process where there was a fluid administered into your body by an injection. Then you are passed through a doughnut type scanner about 30cm thick on a moving bed, I was never completely enclosed. One little point, when you are given the fluid you will experience a strange little sensation in your body. I was told that everyone experiences this in different ways. I had a warm sensation at the back of my head and in my bum (sorry can't think of a better word!). It was all over very quickly, for this scan I was taken into hospital at very short notice and saw the consultant shortly afterwards.
The MRI scan is the one most people think of when told they have to go into hospital for a scan. This is the one where you go into a body length cylinder, (It is open on both ends though). Basically the tube is a series of large magnets. MRI is based on changing the magnetic rotation of the atoms in your body so they align, when the magnetic field is switched off, the atoms return to their original rotations and the scanner creates a picture of your organs by monitoring this movement of atoms and and the speed they return to their original position. It's something to do with the density of the make up of your body, ie flesh, bone, muscle etc and the the different speed that each of these atoms return to their original oscillation, phew, enough of the science!
I was having my torso scanned so before I entered the scanner I was asked to remove all metal objects (although I did forget there was a metal zipper on my jeans. I did remember to take my jeans off for the second time I had a MRI and wore pyjama bottoms!). And a device was strapped to my chest, it was like a rigid life jacked or motorcycle body armour, and this was plugged into the machine. Then I was given a rubber ball type thing, that I was told to squeeze if I wanted the process to stop at any time, and then headphones were put on. From now on all communication was through the headphone set. The bed is then entered into the tube and the scanning begins.
I am not claustrophobic, but can understand that a lot of people are. When I was first was told that I might have cancer, I started listening to anti-stress CD's, and I think this helped me a lot at the time and now. So when I entered the MRI scanner I was quite calm. What I did not expect was how noisy it was going to be, and this might come as a surprise to you also, so be prepared. You can go online and listen to a MRI working, I think it's on youtube, I went there to explain the noise to my wife.
For me the scan consisted of several short little scans where I was asked to hold my breath, and then a longer one between 6-10min (which I didn't have to hold my breath!). I might be imagining this, but for the first scan I was very still and it seemed to go quicker, the second time I was a bit fidgity and it took longer?
By now your father has probably experienced these types of scans this for himself, but I hope it will be of some help to anyone else who might have the same question.
Just read you post about the difference between CT scans and MRI scans abd found this very interesting and helpful.
I had an MRI scan when first diagnosed and found the experience and the noise quite stressful. I also felt very claustrophobic so anxious if I need to have this procedure again in the future. Therefore I would be grateful if you could tell me about the stress tapes you listened to and where I could buy them?
Looking forward to hearing from you.
Hope all is going well for you.

all is well with me, just a bit of the paranoia about my future health.
The book and CD, they come together, I used was called Control Stress (stop worrying and feel good now!),by Paul McKenna. ISBN 978-0-593-05629-5. www.rbooks.co.uk or perhaps you could get it from amazon. It was on offer when my wife bought it from a local bookstore, on the off chance I would use it.
I used to think all this stuff was mumbo-jumbo, but it really works for me!
I fly quite a bit, and not being the best of flyers, use it for the time spent in the departure lounge, but keep an eye on the time as it can get away from you.
I also have a forward thinking (New Age?) doctor here in Denmark, when I told him I have issues with stress, and especially before my operation I told him I was terrified of the anaesthesia, he tried a few things out on me, like hypnotherapy and something called a breakthrough, I think? Dealing with problems when I was a child and trying to resolve them now. When he asked me how far I wanted to back, he kind of intimated to previous lives, I think, which I raised an eyebrow to, but I went along with it and found it all rather good to be honest. I was a bit confused after, but was all right after an afternoon nap!
Hope that has been of some help to you Susan,
