Spinal cord tumors are a common condition in neurosurgery, including neurofibroma, spinal meningioma, ependymoma, glioma, spinal lipoma, and so on.

Magnetic resonance imaging (MRI) plays a crucial role in the preoperative evaluation and planning of spinal cord tumor surgery. It provides detailed information about the tumor's location, size, and relationship to adjacent structures.

However, routine MRI may not always provide sufficient information about the tumor's stiffness or adhesion, which can impact surgical planning and postoperative outcomes. Magnetic resonance elastography and slip interface imaging can help measure the mechanical properties of tissues, including their stiffness or adhesion.

By combining the above methods, surgeons can identify areas of potential tumor adherence or invasion into surrounding structures, allowing for more precise surgical resection and minimizing the risk of damage to critical neural tissue.
