Abstract

Purpose : The purpose of this study was to describe arterial spin labeling MR image findings of status epilepticus. Materials and Methods: A retrospective chart review within our institute revealed six patients who had been clinically diagnosed as status epilepticus and had also undergone MR imaging that included ASL in addition to routine sequences. Results: Six patients with status epilepticus were studied by conventional MR and arterial spin labeling imaging. All patients showed increased regional CBF correlating with EEG pathology. Notably, in two patients, conventional MRI and DWI showed no abnormal findings whereas pCASL demonstrated regional increased CBF in both patients. Conclusion: Arterial spin labeling might offer additional diagnostic capabilities in the evaluation of patients with status epilepticus.

목적: 간질중첩증의 동맥 스핀 라벨링 자기공명영상 소견을 알아보고자 한다. 대상과 방법: 본 기관에 내원한 환자들을 대상으로 후향적으로 검색하여 중 간질중첩증으로 임상적으로 진단받았으면서 동맥 스핀 라벨링을 포함한 자기공명영상검사를 받은 환자들을 찾아 이미지를 분석 하였다. 결과: 총 여섯명의 간질중첩증 환자들이 검색되었으며 이 환자들은 모두 EEG에서 이상소견이 나타난 부위에 국소적 CBF증가 소견을 보였다. 특히 두 명의 환자에서는 DWI를 포함한 고식적 자기공명영상 시퀀스에서 모두 특이 소견 보이지 않았으나 동맥 스핀 라벨링 이미지에서만 국소적으로 증가된 CBF를 보였다. 결론: 간질중첩증 환자들의 진단에 있어서 동맥 스핀 라벨링은 기존 영상검사에 더하여 추가적인 역할을 할 수 있을 것으로 기대된다.
