That just means that there are different degrees of intensity in the signal. Look at it like the different degrees of contrast in a picture...
What does heterogeneous signal mean within pancreas
what does it mean heterogeneous signal in the thyroid gland and a left lobe nodule meawsuring approximately 6mm.
What does loss of signal intensity and disc space height mean
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.
I have added a link to a resource and I in answering your question
A heterogeneous T2 signal means that there are areas within a tissue or structure that have different levels of signal intensity on a T2-weighted MRI image. This can indicate a mix of different tissue types, such as fluid-filled spaces, fibrosis, or inflammation. It may suggest underlying pathology or a mix of normal and abnormal tissue.
The T2 signal is used by MRI machines to help identify different characteristics of tissues within the brain. For example, the T2 signal can help identify if the tissue contains too much water.
I just had an MRI done and one of the comments was that an area of the scan showed a low signal intensity...as in, something is wrong with the tissue.

Signal intensity refers to the brightness of an image on a magnetic resonance imaging (MRI) scan. When evaluating the medial meniscus, signal intensity can help identify abnormalities such as tears or degeneration. Changes in signal intensity of the medial meniscus can indicate injury or pathology.
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.
A fudge i give
Increased signal intensity in an ACL (anterior cruciate ligament) on an MRI image typically indicates injury or pathology, such as a tear or inflammation. This abnormal signal intensity may suggest ligamentous disruption or degeneration, and further evaluation is usually necessary to determine the extent and significance of the findings.
