I have browsed through the board looking for other reports from imaging that have helped. This board has so much great information and positive support.

 

I'm still puzzled by one sentence in my kidney MRI report that I was hoping someone might explain for me.

 

There is a 6 mm T2 hyper-intense lesion which does not clearly displace low signal on contrast enhanced Imaging.

 

I go for follow up this coming week, so hoping for the best.

    Hi Redwe

    Hi Redwe

    For a start you can check out this brief overview answer to a similar question and click on the link in the answer to see the difference between T1 and T2 types of MRI scans.

    You might have to cut and paste that link let me know if you have trouble with it.

    The "hyper-intense" part refers to the intensity of the contrast the lesion projects in the MRI scan.

    Quote "Hyperintense (more intense): If an abnormality is bright (white) on MR, we describe it as hyperintense."

    There are some technical papers on this I will quote from one:

    Quote "The vast majority of focal liver lesions are hyperintense on T2-weighted magnetic resonance (MR) images."

    I hope this helps you begin to understand what was meant by the part of the report you referred to.

    If you'll copy and paste the impressions at the bottom of the report I might be able to make more sense of it. I'm a MRI Technologist but the part about "displace low signal on contrast enhanced imaging" has me confused. Most likely the tumor enhanced after contrast was administered.

    Hi Tesla1,

    Hi Tesla1,

    Thanks for your help.

    These were incidental findings on an MRI of the spine.

    "There is a 6 mm T2 hyperintense lesion in the left kidney, which does not

    clearly displace low signal on contrast-enhanced imaging. There is a 4 mm vague

    liver nodule present in the medial aspect of the left medial lobe, which

    displays enhancement, which may represent a hemangioma. 

    ...

    Impressions:

    ...

    T2 hyperintense lesion in the kidney, which does not display signal dropout on

    post contrast images. If clinically warranted, an ultrasound of the abdomen or

    MRI of the abdomen with and without contrast may be obtained. "

     

     

    I was trying to figure out if the mass on the kidney resembled a cyst. My guess from the language is that it did not have the aspect of a classic cyst. The liver mass was characterized but the kidney lesion was not.

     

    Again, I so appreciate your offer of help and any insights.

    Best,

    Redwe

    Lessons in MRIs

    Supersum,...

    Thanks for starting points.

    1.  T1 scans tend to highlight fatty tissue as white/bright, while water appears dark. T2 scans are the opposite--they highlight watery tissue as white/bright and fatty tissue as dark...

    So T2 hyperintense means bright in T2 view? As you quote "...If an abnormality is bright (white) on MR, we describe it as hyperintense."  I may need to hear this 6-7 times before I can remember it.

    The second link is especially helpful- written for someone about where I am now.

    Thanks!!
