Peri-ictal imaging abnormalities in non-convulsive status epilepticus: A systematic review and meta-analysis comparing magnetic resonance imaging and computed tomography perfusion.

Although ASL exhibited a higher pooled estimate for identifying peri‐ictal abnormalities, the difference between ASL and CTP did not reach statistical significance ( χ 2 = 0.22, p = 0.636), suggesting that both perfusion‐based modalities demonstrated similarly high detection rates for peri‐ictal abnormalities in NCSE.

Although the latter result narrowly missed statistical significance, the consistency between analyses suggests that CTP was associated with a higher detection rate of peri‐ictal abnormalities compared to MRI.
