- Radiologic Classification of Hippocampal Sclerosis in Epilepsy
This review explores how the International League Against Epilepsy (ILAE) subtypes of hippocampal sclerosis correlate with MRI findings. Hippocampal anatomy is reviewed in detail. The pathophysiology of hippocampal sclerosis is discussed. A radiologic classification scheme is proposed that aligns with the ILAE pathology classification, aiming to improve clinical communication and decision-making.
- Temporal Changes on Postgadolinium MR Vessel Wall Imaging Captures Enhancement Kinetics of Intracranial Atherosclerotic Plaques and Aneurysms
MR VWI in patients with symptomatic intracranial atherosclerotic disease plaques and aneurysms showed contrast accumulation beyond the early-phase (5–15 min) into the delayed phase (20–30 min). This nonspecific enhancement may indicate focal inflammation, neoangiogenesis, and/or increased permeability. The authors advocate postcontrast imaging soon after contrast administration to optimize diagnostic accuracy.
