Heterogeneous abnormal marrow signal is what oncologists look for on a magnetic resonance image of a patient's bone as a possible indication of a malignancy, says the American Society of Clinical Oncology. Oncologists often receive consults for workup of "abnormal marrow signal." It is a non-specific, yet important finding usually indicating the presence of underlying pathology.

At birth there is dark T1 signal in the vertebral body ossification centers compared to the more hyperintense disks owing to red marrow and trabecular bone ().The vertebral bodies have thin layers of cartilage at both endplates with brighter T1 signal adjacent to the relatively hyperintense intervertebral disks. Heterogeneous abnormal marrow signal is what oncologists look for on a magnetic resonance image of a patient's bone as a possible indication of a malignancy, says the American Society of Clinical Oncology.
