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.

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.

In this study, the authors developed automated motion correction and used deep learning to generate pseudo-CT cranial images from MR images. Compared with CT, pseudo-CT had 100% specificity and 100% sensitivity for suture closure and 100% specificity and 90% sensitivity for skull fractures.
