Hi, Ineed tohave an mri scan can anyone tell me what happens!!?/?

Question

I was involved in a car crash 4months ago have seen a specialist now need this scan please explain what happens

Answer 1

you lie in a big white tube for between 15 and 45 minutes they will pay music for you but there are lots of loud bangs and things, but dont worry im not even an adult yet and ive had LOADS of the things, they arent scary just take your fave cd!
if your really scared close your eyes it helped me the first time!!!
lol

Answer 2

Read what has been posted for you. Most everyone (with the notable exception of one idiot) has described what you will experience. It is painless. Just a little noisy and you've been told you may have eardefenders to block out the noise. The technician can hear you at all times and can speak to you through the eardefenders. Claustrophobia has also been brought up. If this is a problem, in lieu of a mild sedative that your doctor would prescribe and that you would take prior to the MRI, there are also open MRIs that don't utilize a chamber/tube.

Metal was mentioned. No metal can be worn on the body. No jewelry, no body piercings, no pacemakers or other metal or battery-operated implants (includes hearing aids), no metal dental appliances including braces (these must be removed for the procedure). No makeup should be worn even metallic nail polish. If there is a metal or a battery-operated device that cannot be removed, no MRI can be done.

You will be fine. Consider this an adventure and try to enjoy it.

You have to lie on a bed which can move you into the centre of a doughnut shaped machine. It is about your body length in the tunnel. So it's hard to see out. If you are having your head scanned it has to be put into a coil. That's something akin to a helmet. It has to be close to you a it has to pick up very weak signals that will come off you, to form an image in the machine. It's fairly noisey due to the way it works. Not quite as noisy as a road side drill but close. I can assure you there's nothing to worry about as I have had a scan for my head. While I was in there they played a CD for me and only intterupted when they wanted to give me instructions. The MRI is a big magent that lines up you atoms in one direction, as they are like mini magents(the N & S on a magnet Line up when brought together for example). The scanner then emits pulses of radio waves that causes your atoms to turn. When they turn back into alignment, due to the magnet, they emit energy which the scanner detects. It then forms an image. MRI is very good for soft tissue detail, not so hot for boney detail. There is nothing to worry about as the staff can hear you all the time. The staff should explain everything before you have it but don't wear anything metal as this will be drawn into the magnet and can cause some harm if it came loose. The metal will also affect the images making them no good. Also try not to move as that also ruins the images. Apart from that you get a lie down for an hour.

On July 3, 1977, an event took place that would forever alter the landscape of modern medicine. Outside the medical research community, this event made scarcely a ripple at first. This event was the first MRI exam ever performed on a human being.

It took almost five hours to produce one image. The images were, by today's standards, quite ugly. Dr. Raymond Damadian, a physician and scientist, along with colleagues Dr. Larry Minkoff and Dr. Michael Goldsmith, labored tirelessly for seven long years to reach this point. They named their original machine "Indomitable" to capture the spirit of their struggle to do what many said could not be done.

This machine is now in the Smithsonian Institution. As late as 1982, there were but a handful of MRI scanners in the entire United States. Today there are thousands. We can image in seconds what used to take hours.

MRI is a very complicated technology not well understood by many. In this article, you'll learn all about how a huge, noisy MRI machine actually works. What is happening to your body while you are in the machine? What can we see with an MRI and why do you have to hold so still during your exam? These questions and many more are answered here, so let's get started!

The Basic Idea
If you have ever seen an MRI machine, you know that the basic design used in most is a giant cube. The cube in a typical system might be 7 feet tall by 7 feet wide by 10 feet long (2 m by 2 m by 3 m), although new models are rapidly shrinking. There is a horizontal tube running through the magnet from front to back. This tube is known as the bore of the magnet. The patient, lying on his or her back, slides into the bore on a special table. Whether or not the patient goes in head first or feet first, as well as how far in the magnet they will go, is determined by the type of exam to be performed. MRI scanners vary in size and shape, and newer models have some degree of openness around the sides, but the basic design is the same. Once the body part to be scanned is in the exact center or isocenter of the magnetic field, the scan can begin.

In conjunction with radio wave pulses of energy, the MRI scanner can pick out a very small point inside the patient's body and ask it, essentially, "What type of tissue are you?" The point might be a cube that is half a millimeter on each side. The MRI system goes through the patient's body point by point, building up a 2-D or 3-D map of tissue types. It then integrates all of this information together to create 2-D images or 3-D models.

MRI provides an unparalleled view inside the human body. The level of detail we can see is extraordinary compared with any other imaging modality. MRI is the method of choice for the diagnosis of many types of injuries and conditions because of the incredible ability to tailor the exam to the particular medical question being asked. By changing exam parameters, the MRI system can cause tissues in the body to take on different appearances. This is very helpful to the radiologist (who reads the MRI) in determining if something seen is normal or not. We know that when we do "A," normal tissue will look like "B" -- if it doesn't, there might be an abnormality. MRI systems can also image flowing blood in virtually any part of the body. This allows us to perform studies that show the arterial system in the body, but not the tissue around it. In many cases, the MRI system can do this without a contrast injection, which is required in vascular radiology.

Answer 5

I had an MRI a few years ago. It's not scary and does not hurt. An MRI scan enables the doctors to see inside you in greater detail than an x-ray. MRI stands for Magnetic Resonance Imaging; you lie inside a big tube which contains the magnet. You just wear a hospital gown. The magnet is noisy but often they will play music to you while you are in there. I took a favourite CD in to listen to. You have to keep still (they sedate little kids) so the best thing is to try to meditate, listen to the music & chill....It's over sooner than you think.

Answer 6

For a MRI Scan you don't have to worry at all, I had one of these scans myself as did my 12 year old daughter. The radiographer will take you to where the scan is then they will help you up onto the bed, they will give you earplugs to put in as the machine can be quite noisy. They will then go behind a screen and the bed you are lying on will move slowly into the scanner don't worry you will have a panic button in case you feel slightly claustrophobic. When I went into the machine I closed my eyes and thought of my kids, my scan was over in approximately twenty to thirty minutes, please don't be nervous as it is not invasive I actually fell over to sleep to the drone of the machine.


I hope this is helpful but please please don't worry.
All the best with your scan.

Answer 7

You lie on a bed and get slid into a tube in the middle of the biggest magnet you've probably ever seen.

It takes about 30-45 mins normally, it makes a load of noise and stops, nothing to be worried about- you'll be fine :D

Answer 8

Don't worry, it won't hurt you at all. You lie on a table that takes you into a machine. They'll ask you to lie still. You'll hear some knocks and clicks untill the test is over and you come out. Very simple.

Answer 9

I've had four MRI's in the last few years and they're a breeze. you get to lay down for about 30-40 mins and chill out. the machine is very noisy and you get ear defenders for them but sometimes if you're lucky, and i only had this once, they had the radio playing thru them! also you have to remove all jewellery as the MRI is magnetic. everytime i've been i've had to put a plastic stud in my tongue!! but nothing to worry about. lay back, chill out and doze off if you like!

Answer 10

You are put inside of a metal "tube". They slide you in and out. It can be noisy. If you have claustrophobia they might give you a sedative/Valium/some other benzo to make you relax. It takes anywhere from 30 minutes to 1 hour. Try to go in sleepy and fall asleep.
