    MRI and CT ?!? one versus the other

    okay, I got my CT report and films today. I am confused, is the CT just another version of the MRI, almost to confirm what the MRI said previously?
    For those out there who are somewhat familiar with the lingo, I will type what the MRI said (I know, AGAIN), and then the CT.

    MRI:

    L4-5: Minimal diffuse disc bulge is seen with significant central canal and neural foraminal stenosis (though my NS doesn't seem to see it??)

    L5-S1: Diffuse disc bulge is seen as well as a posterior annular tear without significant central canal or neural foraminal stenosis. Post contrast study demonstrates no definite areas of abnormal enhancement.

    1. Degenerative disc changes seen at L4-5 and L5-S1, predominantly L5-S1 where there is a disc bulge and posterior annular tear.

    I already of course knew pretty much what all this means.

    Now the CT:

    Findings: At l5-S1 there is some contrast in the disc space which is ill-defined and there does appear to be a central disc protrusion which correlates with what seen on the MRI from 08-03-04.

    There is some effacement of the fat medial to the traversing S1 nerve roots bilaterally.

    At L4-5 there is contrast centrally in the disc space, extending to the posterior vertebral body margin in the midline compatible with an annular tear. There is a diffuse disc bulge.

    At L3-4 there is contrast present centrally in the disc space. No annular tear or disc herniation is seen.


    Some of the words I have no idea what they mean-and one odd thing-the annular tear used to be at L5-S1, not L4-5 now it is switched. KINDA ODD????
    Anyway, I would appreciate any feedback, suggestions and what not. THANK YOU!!!!!

    Re: MRI and CT ?!? one versus the other

    some terms I am not familiar with: "ill-defined", "effacement of the fat medial....", "transversing S1 roots bilaterally". Does the last one mean nerve impingement that the EMG did not pick up??? Now I am confused actually when comparing the two tests (MRI/CT)

    I guess no one has anything to add?? well, no biggie. I figured out what most of the terms meant and was able to deduct what was being said. So, off I go at 0930 tomorrow and I will let you know what is said!!!!

    Re: MRI and CT ?!? one versus the other

    Mel,
    When I was having such a problem with claustraphobia (sp?) that I couldnt go into the MRI I asked about a CT scan instead. This was an MRI of the brain to look for tumors. My PCP said that the MRI is more detailed. He said he checked with a specialist, & for what they were looking for the MRI would be best. I dont know if that helps you out much or not. Anway, they tried valium a couple times & I was still not able to do it. Finally they gave me 4 valium & it was a breeze. I have not been that relaxed in years! lol They had to do the same for the MRI of my neck. I had no tumors either. I think that was adding to the stress of the whole thing as well....not knowing for sure what they would find.

    Also, as far as the medical terms. I did not know what some of the terms on my report were so I went on Ask Jeeves.com. I hope its ok that I posted that. It is a good search engine for when you cant find what you are looking for on others. Anyway it brought up some good sites where I could look up the terminology & also find out info regarding my different conditions.

    Take care & good uck tomorrow!

    Breny

    From what the rad tech told me the other day when I was getting a bone density test, the MRI uses magnetic field and the CT scan uses radiation, nukes you. There was an article in this month's Readers Digest, I believe, that stated that the CT scan is not good for you and is actually worse for you than the results that you might obtain. I didn't finish the article but I think that it was pushing the MRI versus the CT scan. I had the MRI scan but am now going to get the CT scan to look for soft tissue damage.

    The tech also said something about the way that the MRI takes slices as opposed to the way that the CT takes slices. Also, the machines are totally different.

    I saw what you were concerned about with the different readings. Were they done by the same radiologist? I would have a convern on these. Have you talked to your doctor and told him that you are *greatly* concerned about the readings? It looks like they may have counted incorrectly or the typist who did the transciption could have been wrong. With one keystroke my lympoma went from benign cyst to cancer, lymphoma. They make mistakes which they need to be called on.

    Have you gotten this straightened out yet? I would have the tests in front of me and have the doctor look at them on the light box and count the discs for you and have him show you where the actual tears are. One of my doctors had to count from the bottom up to get the right disc.

    Are you considering surgery for this problem? The tears are not good. The stenosis is not good. Are you going to have fusion? The reports indicate conditions which have to be causing you a lot of pain. Once those discs tear, in a person your age, the stuff leaks out and causes nerve pain. Ouch!

    My heart goes out to you.
