UNASSIGNED: Purpose. To determine the impact of intraoperative magnetic resonance imaging (iMRI) in @entity302 surgeries on the extent of surgical resection and @entity410 outcome along with its feasibility and limitations. Methods. @entity1 with pharmacoresistant @entity302 (PRE), who underwent surgeries in operating theater equipped with high-field 1.5-Tesla MRI, were evaluated for extent of resection, operative time, scanning time, pathologies, resultant extra resection, and @entity410 outcomes. Results. Thirty-nine @entity1 with mean age of 18 (range: 3-65) years with PRE underwent surgical intervention. Mean duration of @entity302 was 10.2 years. Surgical interventions included @entity5 resection (31%), resection of focal @entity6795 (28%), mesial temporal lobe surgeries (18%), and disconnection surgeries (23%). iMRI alone, apart from navigation and electrophysiology, improved resection rates in 13% (5 out of 39) of these @entity1 . In lesional group, iMRI modified operative strategy resulting in increased resections in 21% (5/23) @entity1 . Complete resection was observed in 87% of @entity1 . iMRI scanning time constituted 25% (mean: 72    21 min) of time spent under anesthesia by the @entity1 . Major and minor complications were observed in 2.5% and 7.5% of @entity1 , respectively. The mean follow-up was 14 months. Favorable postoperative @entity410 control (Engel Classes I and II) was achieved in 85% and complete @entity410 freedom was achieved in 77% of @entity1 (Engel Class IA) at 1-year follow-up. Conclusions. iMRI increases the extent of resection mainly in lesional @entity302 surgeries translating into good @entity410 outcomes but not found to be much beneficial in prototype mesial temporal @entity1463 surgeries and disconnection surgeries.
