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...
In the context of imaging, heterogeneous signal intensity refers to variations in signal strength within a specific region or structure. This variability can be due to different tissue compositions, pathologies, or artifacts, leading to a mixed or irregular appearance on the image.
What does heterogeneous signal mean within pancreas
What does loss of signal intensity and disc space height mean
what does it mean heterogeneous signal in the thyroid gland and a left lobe nodule meawsuring approximately 6mm.

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.

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.

What does this mean: The ACL demonstrates swelling and some slight increased signal in the area of attachment to the distal femur. in knee injury report.
The signal is encoded as light; the light changes intensity, for example a higher intensity for a one, or a lower intensity for a zero. (In practice, more complicated encoding schemes are used.)
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.
Proton density within the tissue will affect the signal intensity on an MRI. The thicker the tissue, the more intense the return signal will be upon detection.
Signal intensity is directly related to relative amounts of fat, water, and cells in the marrow. The words nonspecific mean that it is not pointing towards any specific medical abnormality. The mild edema means that the muscle and other tissues around this area has some water built up (edema). Your doctor should explain it to you in words you can understand.
