Talar Dome MRI Case Study

Images/Data:

3.0 T Coronal PDFS pre and post injection MRI’s of the medial ankle and an OCD in the talardome. The images on the right are 15 months after the injection of adult stem cells into the osteochondraldefect (OCD).

For orientation, the yellow lines point to the dark bony cortex (thick outside of the bone) and the normal grey cartilage.

The white dashed circle is around the OCD and the area of swelling in the bone (marrow edema-the area of light color in the bone). Note that the small white arrow is pointing to a defect in the cartilage (the white horizontal line breaking the grey) that is filled in with grey cartilage again by the time of the post-op images. Note that the dark horizontalbone cortex line is darker, indicating stronger bone under the defect.
