Magnetic resonance elastography and slip interface imaging can help measure the mechanical properties of tissues, including their stiffness or adhesion.\n\nBy 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.",[25],{"label":26,"type":27,"description":28,"interventionNames":29},"Diagnostic（MRE, tumor grading of stiffness and adhesion）","EXPERIMENTAL","Patients undergo a preoperative routine MRI scan and MRE the day before their scheduled surgery.
