- 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.
- MR Cranial Bone Imaging: Evaluation of Both Motion-Corrected and Automated Deep Learning Pseudo-CT Estimated MR Images
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.
