Abstract:
The spine is the most common location for skeletal metastases, and the incidence of spinal metastasis shows an increasing tendency. Because metastatic spinal tumors progress from an anterior element to a posterior element resulting in continuing destruction of the pedicles, epidural extension and involvement of neural structures of the metastatic tumor are eventually visible. Therefore, it is clinically significant for radiologists to understand the pathophysiology of spinal metastasis and to assess the involvement of neural structures and the disintegration of spinal instability related to the pathophysiology. As MRI is also the best imaging modality for diagnosing spinal metastasis, radiologists should accurately assess spinal metastasis and provide practical information to physicians. Therefore, we will describe some analysis points focusing on the understanding of pathophysiology of spinal metastasis and the next step toward a more extensive clinical approach using MR imaging.
