I have L5-S1 has anterolysthesis with foraminal encroachment bilaterally. I am fused from L1 -S1and now the doctor told me that the anterolysthesis is getting worse.
What does "a high signal in the central 3rd of the disk" mean?

Hello there, I saw the doctor today and he told me that a "high signal" can indicate inflammation, infection, and a diseased disk. So it can be either of the three. He doesn't want to do anything at this point.. unless it gets worse.

Hello there, thank you so much for your answer here. I went through over 20 different medical sites to find any information about this "high signal" and found no information at all. All they basically had was the degree of anterolysthesis.
I will be seeing my neurologist this Friday. So when I see him I will write here the information he gave me. Again, thank you so much for your reply.

I'm glad you found this information helpful!

I agree-it was difficult finding this information, and I will be interested to hear if your doctor confirms/denies that this "signal" information relates to the MRI imagining, or to the degree of anterolysthesis. Lab results are so difficult to interpret, and I am happy to hear that you will be seeing your doctor this week, and posting any additional information you receive.

Take care,

From my understanding of MRIs, the image results can be described as "high signal intensity" for areas that may (or may not) be problematic for the patient. Some disks may be "higher signal" than other disks, and it is important to ask your doctor to interpret your specific test results, as these results can differ from patient-to-patient, and even differ in meaning from lab-to-lab. Some differences with disk signal can even be caused by its water or fluid content, blood flow or inflammation, and not necessarily be a degenerative or other condition; other times, it may be indicate an area for further evaluation.

Please let us know what your doctor says, and we can offer more resources of information once you know what your specific lab results indicate.
