3D MRE-Based Evaluation of Meningioma Mechanical Properties and Histological Features
Evaluation of Meningioma Mechanical Properties and Histological Features Using Three-Dimensional Magnetic Resonance Elastography
Shengjing Hospital

INTERVENTIONAL
Conditions
Summary
This prospective single-center study aims to evaluate the feasibility and clinical utility of three-dimensional magnetic resonance elastography (3D MRE) in assessing tumor stiffness and adhesion in patients with meningioma undergoing surgical resection. By correlating preoperative MRE-derived stiffness and adhesion maps with intraoperative findings and histopathological features, the study seeks to determine whether MRE can serve as a noninvasive imaging biomarker for surgical planning, risk stratification, and prediction of tumor behavior.
Eligibility
Inclusion Criteria1
- All patients undergoing meningeoma resection surgery are eligible for inclusion in the study cohort.
Exclusion Criteria7
- Patients with metallic implants or foreign bodies in their bodies (pacemakers, artificial metallic heart valves, metal joints, metal implants, and those who can not remove dentures, insulin pumps, or contraceptive rings)
- Pregnant women in the first trimester (within three months)
- Patients with severe claustrophobia or anxiety
- Patients with severe fever
- Patients who can not tolerate MRE
- Patients with vascular malformations and aneurysms.
- Patients who do not sign an informed consent

Interventions
Participants will undergo preoperative 3D MRE to quantify tumor stiffness and generate adhesion maps. MRE is performed as an adjunct to standard brain MRI, using 60 Hz vibration frequency and specialized elastogram processing software. The resulting stiffness and adhesion data are made available to the neurosurgical team for surgical planning.
During surgical resection, the neurosurgical team will systematically assess and record tumor stiffness, adhesion to surrounding structures, vascularity, resection time, and technical difficulty using a standardized intraoperative scale. These intraoperative findings will be compared to preoperative MRE parameters to evaluate the diagnostic and predictive value of MRE.
