Abstract：Objective To explore the clinical value of combined application of dual-compartment intraoperative magnetic resonance imaging (iMRI) in surgical and general clinical scanning. Methods From March 1, 2019 to December 31, 2019, this study recruited
the 110 patients who underwent intraoperative scanning under the guidance of dual-compartment iMRI device and 4154 in-patients who underwent ordinary MRI scans in iMRI system. Then the benefits and outputs of iMRI equipment under the combined scanning
mode were calculated. And the preoperative, intraoperative and postoperative multi-mode scanning scheme for patients in the dual-compartment iMRI system was formulated, and then the advantages of the scheme were analyzed. Results The combined
scanning approach resulted in a 72.9% increase in revenue for the iMRI device, and no adverse events occurred. The preoperative, intraoperative and postoperative scanning in the dual-compartment iMRI system reduced the waiting time of patients undergoing
surgery，and the results of multi-mode imaging scanning showed that 60.9% of the patients met the surgical requirements in the first intraoperatively imaging, then increased to 91.8% after the second imaging. Conclusion The combined application of 3.0T twocompartment high-field iMRI in surgery and routine clinical scanning greatly improves the use efficiency of the equipment, and multi-mode imaging scheme for intracranial tumors is of great value in guiding surgery.
