The Relationship Between Quantitative T2 Relaxometry and Memory in Nonlesional Temporal Lobe Epilepsy

Summary:  Purpose: We investigated the relationship between preoperative quantitative magnetic resonance imaging (MRI) T2 relaxometry and volumetry of the hippocampi and pre‐ and postoperative verbal memory in temporal lobectomy patients who had nonlesional temporal lobe epilepsy.
