Abstract

Objective: Assessing the diagnostic significance of MR morphometry in determining the localization of focal cortical dysplasias (FCD).

Material and methods: The study included 13 children after surgery for drug-resistant epilepsy caused by FCD type II and stable postoperative remission of seizures (Engel class IA, median follow-up 56 months). We analyzed the results of independent expert assessment of native MR data by three radiologists (HARNESS protocol) and MR morphometry data regarding accuracy of FCD localization. We considered 2 indicators, i.e. local cortical thickening and gray-white matter blurring.

Results: FCD detection rate was higher after MR morphometry compared to visual analysis of native MR data using the HARNESS protocol. MR morphometry also makes it possible to more often identify gray-white matter blurring as a sign often missed by radiologists (p<0.05).

Conclusion: MR morphometry is an additional non-invasive method for assessing the localization of FCD.

[局灶性皮质发育不良：磁共振成像和磁共振形态测量数据的视觉评估]。

目的：评估磁共振形态学在确定局灶性皮质发育不良（FCD）定位方面的诊断意义：评估磁共振形态学在确定局灶性皮质发育不良（FCD）定位方面的诊断意义：研究对象包括13名因FCD II型引起的耐药性癫痫而接受手术治疗且术后癫痫发作稳定缓解（恩格尔分级IA，中位随访时间56个月）的患儿。我们分析了三位放射科专家对原始 MR 数据（HARNESS 协议）和 MR 形态测量数据进行独立专家评估后得出的有关 FCD 定位准确性的结果。我们考虑了两个指标，即局部皮质增厚和灰白色物质模糊：结果：与使用 HARNESS 协议对原始 MR 数据进行视觉分析相比，MR 形态测量法的 FCD 检测率更高。磁共振形态学还能更频繁地识别灰白色物质模糊，因为这是放射科医生经常忽略的一个征象（p结论：磁共振形态测量是评估 FCD 定位的另一种非侵入性方法。
