Questions & Answers
Mri????????
I am going to get an MRI because for the past few months i have been having bad dizzy spells. What exactly is a MRI??
An MRI is a very strong magnet which aligns all of the hydrogen atoms in your body when a radio frequency is introduced. Then, as the frequency is removed, the atoms return to their natural state. The rate at which they do this provides information which is translated into images which represent your anatomy. The images are used for diagnostic purposes and are similar to CT (a.k.a. CAT) scan images, except that MRI visualizes soft tissue best while CT is very good for bone. All you need to know about having an MRI is that you will probably receive an injection (small needle stick) of a contrast material which will help differentiate blood vessels from other tissue; you may NOT enter the magnet area with anything metal in your pockets or on your body (if you have any metal surgical clips or have worked around metal or shrapnel, you may not be eligible for the study); and you will be required to lay perfectly still for at least 30 minutes while your body is placed into a narrow tube and the magnet rotates around you. You will hear loud banging noises, but most facilities provide earphones or earplugs to help with this. Also, you should be given a device to hold to alert the technologist if you have an emergency, and the tech will periodically ask you if you are okay. All in all, most people do really well with the study and it can provide a lot of valuable information to the radiologist. Good luck!
How does an MRI tell the difference between tumors and other masses?
My husband had another MRI. Now they said he has a mass in his colon. They also called it a tumor. How can they tell this with the MRI? The mass could be something else. According to what I have read, lung cancer does not go to the colon.
The word "tumor" really just means mass. That does not imply that it is "cancer", although most people associate tumor with cancer, which is what I think you are worried about. Although depending on the way it appears on the imaging, a tumor may look more cancerous than, say an infection or a benign growth does. A diagnosis depends on the rest of the clinical information (e.g. if there are other masses or metastatic looking lesions else where in the body) or a biopsy of this mass.
Hope this helps.
What is the difference between an MRI and a Cat Scan?
I know that one uses Computer and the other uses Radio waves. I did a cat scan without contrast and it showed liver enlarged. (Radiologist said) Doctor never seen it since it got lost. He sent me for another cat scan with contrast and it was normal. Liver enzymes were slightly elevated. I was still in pain so I went to the hospital and they did a songram which showed the liver enlarged. I want to know how come it didn't show up enlarged on the cat scan but on the sonogram it did? Liver tests showed normal. Would anything different show up if I took an abdominal MRI? I took an MRI of the spine because the doctor thinks it might be a pinched nerve and he is not worried about the liver because the cat scan came out normal. Who do I trust? The Cat Scan or Sonogram?
I'm not comfortable trying to evaluate your tests but I'll tell you the difference.
MRI is using radio waves where the protons are excited and give off energy which is detected external to the body where their signal is interpreted
Cat or CT(you'll hear both terms) are x-rays. The x ray source spins around you and based on the attenuation in the body. An image is reconstructed.
Sonograms are rather iffy since you need to remember, a lot of that stuff in the abdomen won't have any difference in their properties under US(sonogram) unless you're looking for something specific.
The major difference between CT and MR is in the soft tissue contrast. With CT, it's wonderful for its speed and for distinguishing problems due to emergent situations since the attenuation difference is great between tissue and bone. However, it sucks for differentiating soft tissues. It's not easy to see a noticeable difference between liver and stomach for example since they attenuate about the same in terms of x-rays.
MRI is slow so its not good in ER situations however it provides a wealth more information since there is a difference based on healthy versus patholoigal tissue. There WILL BE A DIFFERENCE IN WHAT CAN BE SEEN IN AN MRI DUE TO THE BETTER CONTRAST.
It's possible the liver enlarged in the interim between your tests. Additionally, there is some physiologcal variation based on diet, time of day, lots of factors....
Shoud you have the MRI?
Based on the fact that the doctors don't seem to have a clear picture on what's going on, the MRI will provide them with more information so it might be useful. Will it be definitive? Probably not, the best information for liver and kidney stuff still seems to be chemical rather than imaging.
