Tumor consistency is an important factor in determining the resectability and surgical outcome of meningiomas. This study investigated the use of magnetic resonance fingerprinting (MRF) to distinguish between meningiomas characterized as soft or hard based on intraoperative patient records. Mann-Whitney U tests were used to compare longitudinal relaxation time (T1) and transverse relaxation time (T2) values derived from MRF. Soft meningiomas had significantly higher T1 and T2 values than hard meningiomas. Both T1 and T2 showed good diagnostic performance, suggesting that MRF may provide valuable information for preoperative differentiation of meningioma consistency and help guide the treatment plan.
