An M R I scan image of the spine of a female patient with spinal cord hemangioblastoma on treatment day. The tumor and its surrounding areas are encircled.
An M R I scan image of the spine of a female patient at 12 months post-surgery for spinal cord hemangioblastoma. There is a small change in the size of the arrow-marked tumor.
An M R I scan image of the spine of a female patient at 24 months post-surgery for spinal cord hemangioblastoma. The arrow-marked tumor exhibits a significant change in size compared to 2 years prior.
A set of 3 M R I scan images of the spine of a female patient on treatment day and at 12-and 24-months post-surgery for spinal cord hemangioblastoma. The sequence of a shrinking tumor is observed.
