- Enhancing Lesion Detection in Inflammatory Myelopathies: A Deep Learning–Reconstructed Double Inversion Recovery MRI Approach
This observational study compared the acquisition time, image quality, diagnostic confidence, and lesion detection rates among sagittal T2WI, standard DIR, and DL-reconstructed DIR in patients with inflammatory myelopathies. It was found that DL-reconstructed DIR significantly reduced acquisition time and improved image quality. DL-reconstructed DIR also improved lesion detection, showing superior diagnostic performance in inflammatory myelopathies without compromising diagnostic confidence.
- Deep Medullary Vein Integrity and Relationships with Small Vessel Disease and Interstitial Diffusivity Measures in Patients with a Recent Small Subcortical Infarct
In this retrospective observational study, the authors assessed how DMV integrity relates to MRI-based SVD severity markers and glymphatic function assessed by DTI measures in patients with a recent small subcortical infarct. DMV disruption demonstrated a weak association with SVD, influenced by confounding factors, and a strong relationship with microstructural WM integrity and free water content, suggesting the potential involvement of extracellular fluid in mechanisms leading to vein disruption.
- A Review of Intracranial Aneurysm Imaging Modalities, from CT to State-of-the-Art MR
This review article covers the established imaging modalities (eg, CT, CTA, DSA, FLAIR, 3D TOF-MRA, contrast-enhanced MRA) and novel MR techniques (MR vessel wall imaging, dynamic contrast-enhanced MRI, computational fluid dynamics) of intracranial aneurysm evaluation. Artificial intelligence software and its integration into diagnostic and risk-stratification pipelines for intracranial aneurysms are also discussed.
