Brain
- Cerebral Microbleeds: Different Prevalence, Topography, and Risk Factors Depending on Dementia Diagnosis—The Karolinska Imaging Dementia Study
MR studies in more than 1500 patients with dementia revealed that 22% had microbleedsthat were predominantly lobar and occipital in cases of Alzheimer disease. Patients with microbleeds were older, male, and hypertensive. Prevalence, location, and risk factors of microbleeds varied depending on dementia diagnosis and may be taken into account when anticoagulating such patients.
- Imaging the Intracranial Atherosclerotic Vessel Wall Using 7T MRI: Initial Comparison with Histopathology
In this preliminary study, 7T imaging was capable of identifying not only intracranial wall thickening but different plaque components such as foamy macrophages and collagen. Signal heterogeneity was typical of advanced atherosclerotic disease.
Interventional
- The Maze-Making and Solving Technique for Coil Embolization of Large and Giant Aneurysms
These authors describe the use of 2 intra-aneurysmal catheters to deploy first large coils and then smaller, more traditional coils that ultimately fill the interstices left by the larger coils until aneurysms are tightly packed. When this technique was used to occlude large/giant aneurysms, follow-up angiography revealed no recurrences compared with nearly 40% in a group of similar lesions treated in conventional fashion.

- Open-Angle Glaucoma and Paraoptic Cyst: First Description of a Series of 11 Patients
MR imaging in 11 patients with severe glaucoma and paraoptic cysts is reported. The cysts showed high T2 and variable T1 signal. The authors suggest that these cysts work as valves and may serve to preserve vision.
Pediatrics
- Susceptibility-Weighted Imaging in Pediatric Arterial Ischemic Stroke: A Valuable Alternative for the Noninvasive Evaluation of Altered Cerebral Hemodynamics
Based on imaging findings in 24 pediatric patients,the authors conclude that SWI-DTI mismatch predicts progression in pediatric arterial ischemic stroke. SWI-hyperintense signal is not useful for predicting the development of malignant edemabut SWI should be routinely added to the neuroimaging diagnostic protocol of pediatric arterial ischemic stroke.
Spine
- Systematic Literature Review of Imaging Features of Spinal Degeneration in Asymptomatic Populations
This meta-analysis of the literature reveals that imaging findings of spine degeneration are present in high proportions of asymptomatic individuals, increasing with age. Many imaging-based degenerative features are likely part of normal aging and unassociated with pain.
