An interventional study of Magnetic Resonance Elastography and Assessment and Recording in Spinal Cord Tumors, sponsored by Shengjing Hospital. Recruiting at 1 site in China. Open to participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-02-12.

In spinal cord tumors requiring surgical intervention, the resection difficulty is determined by two significant factors: tumor stiffness and adhesion to surrounding tissue.
The stiffness of the tumor dictates the complexity of removal, while strong adhesion presents additional challenges during the surgical procedure.
This clinical trial aims to assess the clinical utility of magnetic resonance elastography (MRE), in evaluating the stiffness and adhesion of spinal cord tumors and guiding surgical planning to selecting the most appropriate surgical approach for patients with spinal cord tumors.
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.
Exclusion Criteria:
Patients undergo a preoperative routine MRI scan and MRE the day before their scheduled surgery. During surgery, the tumor stiffness and adhesion are assessed and recorded by the surgeon according to established evaluation criteria. It is important to note that the surgeon does not have prior knowledge of the tumor's specific stiffness and adhesion before the surgery. This information is typically obtained through intraoperative assessment and observation.
Diagnostic Test: Magnetic Resonance Elastography · Procedure: Assessment and Recording
Undergo MRE and routine MRI
Also known as: MRE
Undergo grading and recording of tumor stiffness and adhesion during surgery
Surgical assessment of tumor stiffness
The surgeon will score the tumor stiffness in seven aspects, ranging from 1 to 5 points: Tumor size; Shape of tumor; Tumor texture; Stiffness of the tumor's capsule; Stiffness of the tumor's central region; Primary methods of tumor removal; Features of tumor's capsule.
Time frame: Baseline to 6 weeks
Surgical assessment of tumor adhesion
The surgeon will score the tumor's adhesion based on seven aspects, ranging from 1 to 4 points: Stripping instruments; Frequency of use of sharp instruments; Adhesion range; Degree of tumor resection; Cranial nerve anatomy preservation; Brain tissue anatomy preservation; Neurological function (compared with preoperative).
Time frame: Baseline to 6 weeks
