Early bone marrow edema pattern of osteoporotic vertebral compression (OVCF) is well correlated with vertebral deformity types on the follow up MRI. Upper figures show the different signal intensity of OVCF on T1WI according to the early bone marrow edema pattern. Right to left figures: diffuse low signal intensity of VCF; globular low signal intensity of VCF; band-like low signal intensity of VCF. Lower figures show the vertebral deformity types of the follow up MRI. Right to left figures: anterior wedge deformity; biconcave deformity; crush deformity which is defined as entire vertebral body collapse. The severe degree of vertebral height loss, vertebral osteonecrosis, and spinal stenosis were more frequent in patients with diffuse low SI pattern.
