Degenerative marrow signal change refers to alterations observed in bone marrow, typically seen on imaging studies like MRI, due to degenerative processes such as osteoarthritis or disc degeneration. These changes often manifest as variations in signal intensity, indicating the presence of edema, fatty replacement, or other structural changes in the marrow. Such findings can help in diagnosing conditions related to joint and spine degeneration, providing insights into underlying pathology. It's important to correlate these imaging findings with clinical symptoms for accurate diagnosis and management.

What is Modic-2 degenerative endplate changes?
Modic changes, a common observation in MR imaging, are signal intensity changes in vertebral body marrow, adjacent to the endplates of degenerative discs.Michael T. Modic, MD, professor of radiology and neurology at Case Western in Cleveland, wrote about these changes in the journal Radiology in 1988, and his name has been associated with these changes ever since.Modic changes take 3 main forms:Type I· Decreased signal on T1, and increased signal on T2.· Represents marrow edema.· Associated with an acute process.· Histological examination shows disruption and fissuring of the endplate and vascularized fibrous tissues within the adjacent marrowType II - the most common type· Increased signal on T1, and isointense or slightly hyperintense signal on T2.· Represents fatty degeneration of subchondral marrow.· Associated with a chronic process.· Histological examination shows endplate disruption with yellow marrow replacement in the adjacent vertebral body.Type I changes convert to Type II changes with time, while Type II changes seem to remain stable.Type III· Decreased signal on both T1 and T2.· Correlate with extensive bony sclerosis on plain radiographs.· Histological examination shows dense woven bone; hence, no marrow to produce MRI signal.MODIC CHANGES on MRIT1T2SignificanceTYPE 1¯­EdemaTYPE II­® (or slight­)Fatty DegenerationTYPE III¯¯Bony Sclerosis
What is an heterogeneous marrow signal?
Heterogeneous marrow signal refers to the appearance of bone marrow on MRI imaging that is not uniform in signal intensity. It can result from a variety of causes, such as inflammation, infection, bone marrow edema, or infiltrative diseases. Further evaluation is often required to determine the underlying cause.
What is Heterogeneous marrow signal?
Well, darling, "heterogeneous marrow signal" simply means that the appearance of the bone marrow on a medical imaging study, like an MRI, is not uniform. It can be caused by various factors like inflammation, infection, or even certain types of cancer. So, if your doctor mentions this, it's time to have a little chat about what's going on in your bones.
What does marrow signal unremarkable mean on a MRI?
It means nothing to worry about.
What is heterogenous marrow?
Heterogeneous marrow signal indicates that the bone marrow lacks uniformity. The cause of this may be a fracture, cancer, tumor, or it may just be nothing to worry about at all.
What does the small focus of marrow signal alternation mean?
The small focus of marrow signal alteration could indicate a localized change in the bone marrow tissue, which might be due to different factors such as inflammation, infection, trauma, or a benign lesion. Further imaging studies or clinical evaluation may be needed to determine the specific cause and potential implications.

What does abnormal bone marrow signal mean?
When an mri shows abnormal bone marrow signals in the hip, there could be a number of causes. The causes vary based on whether the abnormality is in the red or yellow marrow. You will need to consult a physician to discuss the possible reasons for the abnormality.
What does abnormal marrow signal mean?
Abnormal marrow signal typically refers to changes seen on an MRI or other imaging studies that suggest abnormalities in the bone marrow, such as inflammation, infection, trauma, or cancer. Further evaluation and possibly a biopsy may be needed to determine the specific cause of the abnormal signal.
What is discogenic marrow endplate at C5-6?
Discogenic marrow endplate changes at C5-6 refer to degenerative alterations in the vertebral endplate at that specific level of the cervical spine, likely due to wear and tear over time. This can lead to decreased disc height, altered biomechanics, and potentially contribute to symptoms such as neck pain or radiculopathy. Treatment may involve conservative measures like physical therapy, pain management, or in some cases, surgery.
What does unremarkable bone marrow signal mean?
"Unremarkable bone marrow signal" typically indicates that the bone marrow appears normal without any significant abnormalities or abnormalities detected on imaging studies such as magnetic resonance imaging (MRI) or computed tomography (CT). This finding suggests that there are no signs of infection, inflammation, or tumor infiltration in the bone marrow.
